Damperless Multi-Plate Converter Clutch Kit
Part No. BW-RK-3

View Instructions

When diesel trucks are modified for racing or street use, OE clutch plates slip and fail to hold. Upgrading to an aftermarket multi-plate converter is the only solution.

Sonnax heavy duty, damperless multi-plate converter clutch kit BW-RK-3 is available for BorgWarner 310mm converters. The Sonnax kit pairs the salvaged OE fluid coupling parts (impeller, stator and turbine) with new heavy duty front cover, clutch plates, piston and turbine hub to increase overall converter capacity. Clear instructions, minimal setup and easy assembly make these foolproof upgrades. All-new kit components eliminate the rework and limitations associated with salvaged parts.
