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

Sonnax multi-plate clutch kit BW-RK-2A improves holding capacity in the BorgWarner 310mm converter without sacrificing stock shift action. Clear instructions, minimal setup and easy assembly make these foolproof upgrades. All-new kit components eliminate the rework and limitations associated with salvaged parts.

Enhanced design features include:

  • Fully-machined, forged piston and custom damper rivets won’t bend under extreme lockup pressure.
  • Piston is tested and proven to withstand bending up to 400 psi.
  • Spring end caps limit how far springs compress under load to prevent breakage.
  • Increased oil flow improves cooling and lubrication of clutch plates.
  • Patented piston/damper assembly absorbs up to 1,250 ft-lbs. of torque.
  • Three solid, non-segmented, high-thermal, high-torque capacity friction elements.

  • Patent No. 7,770,704
