68RFE, 68RFE Multi-Plate Performance Converter

Performance Converter Kit
Part No. CH-RK-6

View Instructions

When diesel trucks are modified for either racing or street use, OE clutch plates slip and just do not hold. Upgrading to an aftermarket multi-plate converter is the only solution.

Sonnax offers heavy duty, performance converter kit CH-RK-6 for 68RFE converters. The damperless Sonnax kit pairs the salvaged OE fluid coupling parts (impeller, stator and turbine) with a 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.

  • Fully-machined, forged chromoly damperless piston features heat treated splines and won't bend under extreme lockup pressure.
