More Details on Our Top Picks
Twin Cam Extra Clutch Plates Friction Steel Clutch Kit for Harley Softail Touring Dyna Trike 1998-2017
This kit stands out for its combination of durability and smooth shifting, making it an excellent upgrade for riders seeking reliability under demanding conditions. Compared to the Energy One® Btx-11 kit, it offers enhanced control thanks to its composite friction plates that reduce clutch noise and improve feel. However, it excludes models with slipper or assist clutches, which could be a drawback for some. The inclusion of high-quality steel and composite materials ensures longevity and heat resistance, translating into better performance during aggressive riding. Its straightforward installation process and detailed instructions make it accessible for most experienced DIY enthusiasts. While it may not suit riders with slipper clutch setups, it’s a dependable choice for those wanting a durable, high-performance upgrade.
Pros:- Enhances shifting smoothness and responsiveness
- Constructed with durable steel and composite materials
- Easy to install with included instructions
- Reduces clunking and improves neutral engagement
Cons:- Excludes models with slipper or assist clutch mechanisms
- Requires soaking plates in oil before installation
- Compatibility limited to specific Harley models

Extra Plate Sportster Friction Steel Clutch Disc Kit for Harley Davidson and Buell Models
Compared with the Twin Cam kit, this option offers a broader compatibility range from 1990 to 2017, making it a versatile choice for many Harley and Buell owners. Its segmented design and high-quality steel and composite plates improve heat dissipation, which helps prevent clutch fade during extended or aggressive riding. The installation process is straightforward, but it does require soaking friction plates in oil beforehand—similar to the Twin Cam kit—adding a small prep step. While it’s more expensive than stock parts, its enhanced heat management and durability justify the cost for riders pushing their bikes harder. This kit makes the most sense for those who want a reliable upgrade across multiple models without sacrificing performance or needing frequent replacements.
Pros:- Improves shifting smoothness and responsiveness
- Enhanced heat dissipation prolongs plate life
- Highly compatible across Harley and Buell models

Cons:- Requires soaking friction plates in oil before installation

Not ideal for: Budget-conscious riders or those with models outside the specified years who seek a cheaper, stock replacement
- Compatibility:Harley Davidson 1990-2017, Buell 1991-2002
- Number of Plates:17 pieces (9 friction, 8 steel)
- Material:Steel and composite paper
- Design:Segmented for heat dissipation
- Replaces:HD P/N 37911-90, Kevlar P/N 307-30-10011

Energy One® Btx-11 Big Twin Sportster XL Buell Performance Extra Plate Kit
This kit is tailored for performance-minded riders who appreciate precise pre-measured stacks and American manufacturing quality. Unlike the other options, it eliminates double riveted steel plates, which can help reduce clutch drag and improve response. Its pre-measured friction ring simplifies installation, but the lack of detailed instructions may require professional help for some users. While it’s limited to certain years and models, the USA-made friction material ensures a high standard of quality and performance. Compared to the other kits, it’s especially suited for enthusiasts who want a straightforward, American-made upgrade that emphasizes performance over raw durability. It’s best for experienced riders comfortable with professional installation if needed.
Pros:- Pre-measured stack height simplifies installation
- Made in the USA with high-quality materials
- Eliminates double riveted steel plates for better response
- Suitable for multiple Harley and Buell models
Cons:- Limited to certain years and models
- No detailed installation instructions provided
- May require professional installation for best results
Best for: Performance-focused riders with 1990-1997 Big Twin, Sportster, or Buell bikes seeking a high-quality, USA-made clutch kit

Our verdict“This performance kit is ideal for experienced enthusiasts who want a precise, American-made upgrade for select Harley and Buell bikes.”
All Balls Racing Big Twin Starter Drive for Harley-Davidson (2007+)
While this product doesn’t directly impact clutch performance like the other kits, it plays a key role in clutch longevity during hard starting conditions. Compared with clutch-focused kits like the TOFR Extra Clutch Plate & Spring Kit, this upgrade targets clutch life under stress, making it suitable for riders who frequently start their bikes in tough conditions. It’s a reliable aftermarket replacement that meets OEM standards, but it’s limited to models from 2007 onward, and installation may require some mechanical skill. This drive improves clutch engagement reliability rather than outright performance, but for riders seeking durability under demanding start-up scenarios, it’s a sensible addition. Its main tradeoff is that it doesn’t enhance clutch feel or responsiveness directly.
Pros:- Improves clutch life during hard starting conditions
- Meets or exceeds OEM specifications
- Includes 1-year warranty
- Reliable aftermarket replacement
Cons:- Limited to specific Harley models from 2007+
- No detailed installation instructions
- Does not directly influence clutch performance
Best for: Harley Big Twin owners needing a durable starter drive to withstand frequent or tough starts from 2007 and later
Not ideal for: Riders seeking direct clutch performance upgrades or with models outside 2007+ range
- Type:Starter Drive
- Compatibility:Harley Big Twin 2007+
- Warranty:1 year
Our verdict“This starter drive is best for Harley owners prioritizing clutch longevity under tough starting conditions on models from 2007 onward.”
TOFR Extra Clutch Plate & Spring Kit for Harley Big Twin 1998-2016
This kit makes a strong case for riders seeking enhanced torque transfer and heat dissipation. Its inclusion of a stronger diaphragm spring—10% more robust than stock—delivers better torque handling, especially during aggressive riding. Compared to the Energy One® Btx-11 kit, it emphasizes increased spring strength to improve clutch engagement under load. However, it might require professional installation due to the spring change and is limited to Harley Big Twins from 1998 to 2016. While it excels in durability and torque capacity, its focus on spring strength could lead to a slightly harsher clutch feel. For riders demanding more torque capacity and heat management, this kit delivers solid performance, but it’s less suited for those wanting the lightest clutch pull.
Pros:- Stronger diaphragm spring improves torque transfer
- Better heat dissipation enhances clutch lifespan
- Reliable and durable for aggressive riding
- Includes friction plates, drive plates, and spring
Cons:- May require professional installation due to spring change
- Potential for increased clutch pull effort
- Specific to Harley Big Twins 1998-2016
Best for: Harley Big Twin riders needing increased torque capacity and better heat dissipation for demanding riding conditions
Not ideal for: Casual riders or those seeking the lightest clutch pull or simple OEM replacement
- Fits:Harley Big Twin 1998-2016
- Includes:9 friction plates, 8 steel drive plates, 1 diaphragm spring
- Spring Strength:10% stronger than stock
Our verdict“This kit is ideal for riders who need increased torque capacity and better heat management in their Harley Big Twin, accepting a slightly firmer clutch feel.”
Twin Cam Extra Plate Steel Clutch Kit for Harley Davidson Touring, Softail, Dyna, Trike 1998-2017, Evolution 1340 1998-1999
This kit stands out for combining high-quality steel and composite friction plates to deliver noticeably smoother shifting and better grip, especially when compared to standard OEM components. It’s well-suited for riders seeking a reliable upgrade that reduces clutch slippage and noise, making it ideal for daily riders and long-distance cruisers. The inclusion of durable materials ensures longevity, but it’s incompatible with models featuring slipper or assist clutch systems, which could limit its applicability. Installation is straightforward with clear instructions, though the plates require soaking in oil beforehand to ensure proper function. Compared to the TOFR Harley Big Twin Clutch Plate & Spring Kit, this offers a more comprehensive set of friction and steel plates, making it a versatile choice for most Harley Big Twins from 1998-2017. It balances performance enhancement with ease of installation, making it the best overall pick for riders wanting a durable, smooth-operating clutch upgrade.
Pros:- Improves shifting smoothness and clutch grip
- Constructed with durable, high-quality steel and composite plates
- Easy to install with detailed instructions
- Reduces clutch noise and slippage
Cons:- Not compatible with models featuring slipper or assist clutches
- Requires soaking in oil prior to installation for optimal performance

This kit is tailored for Harley Big Twins from 1999 to 2016, offering a full set of friction and steel plates along with a heavy-duty spring to enhance engagement and heat management. Unlike the Twin Cam Extra Plate Steel Clutch Kit, it emphasizes a complete rebuild, making it better suited for riders needing to restore or upgrade their clutch system for demanding riding conditions. Its OEM fitment and easy installation make it a straightforward upgrade, but it’s limited to models within the specified years and won’t suit newer or non-standard setups. The inclusion of a heavy-duty spring helps prevent clutch fade during aggressive riding, though it may require mechanical expertise for proper installation. Compared to the Mofun Extra Plate Friction Steel Clutch Kit, this option provides a more complete set with spring upgrades, making it ideal for riders seeking durability and heat dissipation. It’s a solid choice for those who want a comprehensive rebuild kit for mid-2000s Harley Big Twins.
Pros:- Includes friction plates, steel drive plates, and a heavy-duty spring

Mofun Extra Plate Friction Steel Clutch Kit for Harley Twin Cam
This kit offers a balance of durability and performance for Harley Twin Cam models from 1998 to 2017, with steel and composite materials designed specifically for high heat resistance. Compared to the Twin Cam Extra Plate Steel Clutch Kit, it emphasizes increased surface area to improve responsiveness and shifting smoothness. Its compatibility with a wide range of models makes it versatile, but it requires soaking in oil before installation, which adds a step that may be inconvenient for some. The inclusion of durable materials ensures long-term performance, though it lacks specific warranty information, raising questions about longevity. The focus on high heat resistance makes it suitable for riders pushing their bikes hard, such as those doing spirited riding or touring. If you value a high-performance clutch that resists fade, this is a solid choice, though it’s limited to certain Harley models and requires careful prep.
Pros:- High heat resistance with durable materials
- Increased surface area for improved responsiveness
- Designed for a wide range of Twin Cam models
- Easy to install with included instructions
Cons:- Requires soaking plates in oil before installation

This kit offers a comprehensive set of 19 plates, including high-quality, heat-resistant steel and friction components, making it one of the most versatile options for Harley Twin Cam models from 1999 to 2017. Compared to the other kits, it provides a large surface area that promotes smoother shifts and longer lifespan, suitable for riders who want a straightforward upgrade with broad model compatibility. It’s easy to install with clear instructions, but the thicker fiber plate needs careful handling to ensure proper fit, and soaking in fluid for 8 hours is required before installation. Unlike the TOFR kit, which emphasizes heat dissipation, this option focuses on broad compatibility and durability, fitting a wide array of models. If your goal is a reliable, long-lasting clutch with minimal fuss, this kit delivers excellent value.
Pros:- Wide compatibility across 1999-2017 Harley Twin Cams

This conversion kit is tailored for Harley Big Twins from 1999 to 2017, excluding the narrow primary models from 2013-2017, offering a complete package that includes a clutch spring conversion and multiple plates. Its main advantage over the others is the ability to fine-tune clutch engagement through a diaphragm spring to six coil springs conversion, providing a more precise, smoother operation. Compared with the TOFR Harley Big Twin Clutch Plate & Spring Kit, it offers more flexibility in adjustment, especially for riders wanting a more customized clutch feel. The installation may require some mechanical skill, particularly with the spring conversion, and it’s not compatible with models outside the specified years. This kit is best suited for enthusiasts looking to optimize clutch feel and response, especially during spirited riding or heavy-duty use.
Pros:- Allows fine-tuning of clutch engagement
- Includes comprehensive plates and conversion components
- Enhances clutch smoothness and responsiveness
- Suitable for a broad range of Harley Big Twins

- Includes:Clutch spring conversion kit, 9 friction plates, 8 steel plates
- Conversion Type:Diaphragm spring to six coil springs

Our verdict“This kit is best suited for riders seeking a finely adjustable clutch system with smoother operation and precise control.”

This comprehensive kit from ENERGY ONE offers a well-rounded upgrade for 1990-2002 Harley Big Twin, Sportster, and Buell models, making it ideal for riders seeking a reliable, high-performance clutch with simplified installation. It stands out for including friction plates, drive plates, and a stronger diaphragm spring, which together boost heat dissipation and durability. Compared to the Barnett Kevlar Clutch Kit, this set provides a more complete solution with a pre-set stack height, reducing installation guesswork, but it is limited to specific models and requires some mechanical skill. Its 15% stronger spring enhances clutch longevity without sacrificing smooth engagement, perfect for riders pushing their bikes harder. However, it lacks extensive user feedback, which might make some hesitant. Overall, this kit makes the most sense for experienced enthusiasts wanting an all-in-one performance upgrade for select Harley models.
Pros:- Includes a complete set of friction and drive plates for high performance
- Pre-set stack height simplifies installation
- 15% stronger diaphragm spring enhances durability

- Manufacturer:ENERGY ONE
- Item Weight:5 pounds
- Manufacturer Part Number:BTX-11Combo
- Applicable Models:1990-1997 Big Twin, 1991 & later Sportster, 1991-2002 Buell

Big Twin 91-17 Sportster Extra Clutch Friction Steel Plate 17pcs Clutch Kit
This kit is designed for a broad range of Harley Sportster models from 1991 to 2017 and Buell models, making it a top choice for riders prioritizing longevity and consistent performance. Its combination of high-quality steel and friction plates improves clutch engagement and reduces slipping, especially under high heat conditions—an area where the Barnett Kevlar Clutch Kit might fall short due to its Kevlar plates’ wear characteristics. The included 17 plates (8 steel, 9 friction) facilitate smoother shifts and increased surface area for better heat dissipation. However, installation involves primary fluid drainage and disassembly, which could be daunting for less experienced mechanics. Its compatibility is limited to specific models, and professional installation might be recommended for best results. This kit suits riders who want a durable, high-performance clutch upgrade that emphasizes longevity and smooth operation.
Pros:- Enhances clutch engagement and shifting smoothness
- High-quality steel and friction materials resist heat and wear
- Includes enough plates for increased surface area and durability
Cons:- Installation requires primary fluid drainage and disassembly, potentially complex

- Material:High-quality durable steel and premium friction material
- Replacement Part Numbers:HD P/N 37911-90, Kevlar P/N 307-30-10011
Our verdict“This kit is best suited for riders wanting a durable, high-performance clutch upgrade tailored to Sportster and Buell models with a focus on longevity.”
Barnett Extra Plate Clutch Kit for Harley 98-13 Big Twin, Kevlar
The Barnett Extra Plate Clutch Kit offers a durable Kevlar solution for Harley Big Twins from 1998 to 2013, making it a reliable choice for riders seeking increased heat resistance and longevity. Unlike the ENERGY ONE kit, which is more comprehensive but model-specific, this set focuses on durability with Kevlar friction plates and a heavy-duty diaphragm spring, ideal for riders who demand consistent performance over time. Its compatibility across a wide range of Big Twins enhances its appeal, but installation may require mechanical skill, especially when replacing worn components. The exclusion of certain 2013-2016 models limits its scope, and availability of parts can be a concern. Overall, this kit offers a solid balance of durability and performance for riders who want a straightforward upgrade with proven materials.
Pros:- Durable Kevlar friction plates resist heat and wear
- Heavy-duty diaphragm spring enhances clutch lifespan
- Compatible with multiple Harley Big Twin models
Cons:- Excludes some later 2013-2016 models, limiting applicability

- Includes:10 Kevlar friction plates, 9 steel drive plates, heavy-duty diaphragm spring

This set caters specifically to Harley Sportster models from 1991 to 2003, including XL1200 and XL883 variants, and provides a balanced mix of steel and friction plates designed for high heat resistance. Compared with the Big Twin 91-17 Sportster Kit, this set emphasizes sealing with a high-quality gasket, which can prevent leaks during aggressive riding. Its inclusion of extra plates (one more friction and steel) boosts clutch surface area, translating into more reliable engagement and longer service life. Installation might be more involved, especially for those unfamiliar with clutch disassembly, but the extensive model coverage makes it worthwhile for classic Sportster riders. It’s less suited for riders with later models or those seeking a universal kit, but perfect for those maintaining vintage Harley Sportsters.
Pros:- Compatible with a wide range of Sportster models from 1991-2003

Its focus on Kevlar materials ensures longer-lasting performance compared to standard organic plates, especially under aggressive riding conditions. The included heavy-duty diaphragm spring enhances the clutch’s overall resilience, similar to the ENERGY ONE kit but with a more straightforward, single-application focus. Its exclusion of certain 2013-2016 models limits its applicability, and installation may require mechanical skill, especially for those unfamiliar with clutch work. This kit is best for riders who want a reliable, Kevlar-based upgrade that delivers consistent performance without fuss.

Choosing the right high performance clutch kit for your Harley Big Twin involves understanding several key factors. Beyond raw power, consider how the kit affects rideability, longevity, and compatibility. The wrong choice can lead to premature wear, difficult installation, or even damage to your transmission. By examining these critical aspects, you can make an informed decision that enhances your riding experience and aligns with your budget and skill level.Material Quality and Durability
High performance clutch kits often use materials like Kevlar, reinforced steel, or specialty composites. These materials impact how well the clutch resists heat and wear, especially under aggressive riding or long-distance touring. Investing in higher-grade materials generally means a longer-lasting clutch and better grip, but it also tends to increase the cost. Consider your riding style—if you frequently ride hard or tow heavy loads, durability should be a top priority.
Compatibility and Fitment
Harley Big Twin models vary across years and configurations, so verifying compatibility is essential. A clutch kit that fits perfectly ensures smooth operation and reduces the risk of slipping or uneven engagement. Many kits specify the exact Harley model and year range they support. Fitting issues can lead to installation headaches or compromised performance, so double-checking this aspect saves time and money.
Performance Gains vs. Ease of Installation
Some high performance kits require advanced mechanical skills or special tools, while others are designed for easier installation by DIY enthusiasts. Kits with complex assembly might offer marginally better grip but can be frustrating for those without experience. Conversely, simpler kits might deliver good performance with less setup hassle. Balance your skill level with your performance expectations to find the right fit.
Cost and Long-Term Value
Higher-end kits often cost more upfront but can provide superior longevity and performance, saving money over time. Cheaper options may seem attractive initially but tend to wear out faster or provide less consistent grip. Assess your budget against your riding ambitions—if you ride aggressively or plan to keep your bike for years, investing in a premium kit might be more cost-effective in the long run.
Maintenance and Longevity
High performance clutch kits generally require periodic inspection and maintenance to sustain peak performance. Materials like Kevlar or high-grade steel resist wear but still need adjustment and occasional replacement of springs or friction plates. Proper maintenance extends the life of the clutch and maintains consistent engagement, especially important for riders who push their bikes regularly.
Frequently Asked Questions
Will a high performance clutch kit fit my specific Harley Big Twin model?
Most high performance clutch kits specify compatible Harley Big Twin years and models. It’s essential to check the product details and verify fitment before purchasing. Many brands provide compatibility charts or consultative support to ensure the kit matches your bike’s specifications. Proper fitment not only guarantees performance but also prevents installation issues and potential damage.
How much of a performance improvement can I expect from a high performance clutch kit?
The improvement varies depending on the kit and your existing setup, but generally, you can expect better grip, smoother engagement, and more consistent performance under stress. Some kits enhance the clutch’s ability to handle high horsepower or torque, which is especially beneficial for modified bikes or aggressive riding. Keep in mind that the perceived upgrade depends also on your current clutch condition and riding style.
Are high performance clutch kits suitable for everyday riding or only for racing and aggressive use?
Many high performance clutch kits are designed to improve daily riding as well as aggressive use, provided they are selected appropriately. Kits with Kevlar or reinforced steel tend to offer durability for regular use, while more aggressive options may prioritize grip at the expense of some smoothness. Consider your typical riding conditions and choose a kit that balances performance with comfort for everyday riding needs.
What maintenance is required after installing a high performance clutch kit?
Post-installation, regular inspection of clutch components is important to maintain performance. This includes checking for wear on friction plates, springs, and other hardware, as well as ensuring proper adjustment of clutch cable or hydraulic systems. Periodic replacement of worn parts extends the clutch’s lifespan and keeps engagement smooth. Following the manufacturer’s maintenance recommendations helps prevent issues and preserves performance.
Is it worth investing in a high performance clutch kit if I don’t plan to modify my bike further?
Investing in a high performance clutch kit can still offer benefits like smoother operation, better heat resistance, and improved durability, even if you don’t plan additional modifications. It can enhance your riding experience by providing more consistent engagement and potentially extending the life of your clutch assembly. However, if your stock clutch is functioning well and your riding style is moderate, a less expensive, stock-compatible kit might suffice.
