STM Dry Clutch Conversion Kit
STM, an Italian company renowned for high-performance racing clutches, offers a dry slipper clutch conversion kit (model KTT‑3500) that converts from a conventional wet clutch system to a lightweight, dry clutch system for Harley-Davidson Milwaukee Eight Engine (all models). Slipper clutch reduces rear-wheel hop on aggressive downshifting, improves performance, shift feel, and engine-brake control. Equipping your bike with any of the STM clutches allows an overall improvement of the vehicle's performance, also extending the life of the engine.
Precisely machined, lightweight materials (high-strength aluminum) and strong craftsmanship
The kit includes:
- CNC-machined engine cover conversion parts
- A dry slipper clutch assembly
- STM-manufactured 48‑tooth basket (Z48) and matching clutch plate set
- STM Slipper Clutch Tool (121 and 125mm Spring) for proper torquing
