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.
Unleash more usable power from your Milwaukee-Eight Touring machine with this Harddrive cush drive chain conversion kit. Engineered to swap your factory belt drive for a robust chain setup, it delivers a noticeable boost in torque.
Why riders pick this
- Converts belt drive to chain for improved power delivery
- CNC-machined billet aluminum hub adapter
- Heat-treated steel 51T rear and 24T transmission sprockets
- Lower gearing for enhanced torque response
- Integrated cush drive dampening
- Designed for 2017-up Harley Milwaukee-Eight Touring models
This Harddrive cush drive chain conversion kit is specifically designed for 2017-up Harley-Davidson Touring models. By replacing your stock belt drive with a chain, you gain a lower gear ratio that translates directly into more grunt off the line and stronger pull through the RPMs. It's a critical upgrade for riders pushing their Milwaukee-Eight bikes harder.
Enhanced Durability and Power Transfer
- CNC-machined billet aluminum hub adapter ensures a precise fit
- Heat-treated steel sprockets (51T rear, 24T transmission) for long-lasting performance
- Lower gearing optimizes power delivery for a more aggressive ride
- Cush drive dampening helps smooth out power pulses and protect your driveline
Ready for the Road Ahead
Converting to a chain drive is a popular modification for performance-oriented riders looking for maximum power transfer and the ability to easily change gearing. This kit provides the core components needed for the swap. You will need to source a 530x130 link chain separately and have it cut to the correct length for your specific setup.
