Harddrive Cush Drive Chain Conversion Kit Black - Harley & Indian V-Twin
About Harddrive
Harddrive is the house performance and replacement line built for American V-twins, covering everything from engine hardware and electrical to controls, lighting and chassis parts. The range is aimed squarely at Harley-Davidson and Indian riders who want a direct-fit part without dealer pricing, and it spans decades of model years — from Evolution-era Softails to current Milwaukee-Eight baggers.
Unlock the full potential of your V-twin motorcycle with the Harddrive black cush drive chain conversion kit. This high-performance upgrade replaces your belt drive with a robust chain system, delivering a lower gear ratio for increased torque and usable power.
Why riders pick this
- Converts belt drive to chain for improved power
- Black billet aluminum hub adapter
- Durable heat-treated steel 51T rear and 24T transmission sprockets
- Lower gear ratio for increased torque
- Includes spacer and bearing assembly
- Designed for V-twin motorcycles with cush drive hubs
This Harddrive cush drive chain conversion kit is designed for V-twin motorcycles, providing a critical upgrade for riders looking to maximize their bike's performance. By converting from a factory belt drive to a chain, you gain a lower gear ratio that translates directly into more aggressive acceleration and a stronger pull throughout the RPM range. It's a proven modification for both custom builders and performance enthusiasts.
Engineered for Performance and Style
- CNC-machined billet aluminum hub adapter plate for a precise fit
- Heat-treated steel sprockets (51T rear, 24T transmission) for long-lasting durability
- Lower gearing than stock 6-speed for a significant boost in usable power
- Includes spacer and bearing assembly for a complete driveline conversion
The Foundation for a Powerful Build
The sleek black finish of this kit offers a stealthy, custom look while delivering the functional benefits of a chain drive. This upgrade is ideal for riders who demand more from their V-twin, whether for aggressive riding, track performance, or simply a more direct and responsive feel. Remember, a 530x130 link chain is required and sold separately; ensure it is accurately measured and cut to fit your specific V-twin model for optimal performance.

Common questions
What chain size is compatible with this conversion kit?
You will need a 530x130 link chain, which is sold separately. It's essential to have the chain properly measured and cut to the specific length required for your V-twin motorcycle.
Will this kit require a dyno tune after installation?
While this kit changes your gearing, a dyno tune is typically not required solely for a chain conversion. However, if this is part of a larger performance build, a tune is always recommended to optimize your engine's output.
How can I confirm if this kit fits my V-twin?
This kit is designed for V-twin motorcycles with cush drive rear hub systems. We recommend using the Shop by Bike feature on our website to verify compatibility with your specific year and model before making a purchase.
