Performance Converter Kit
Part No. FD-RK-16A

View Instructions

When Ford 6.4 liter diesel engines 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 performance converter kit FD-RK-16A improves holding capacity in the Ford 5R110W 8-stud 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-lb of torque, nearly twice the stock capacity of the Ford 5R110W damper
  • Three solid, non-segmented, high-thermal, high-torque capacity friction elements
  • Front Cover
  • Clutch Plate with Internal Splines
  • Clutch Plate with External Splines
  • Damper Assembly
  • Thrust Bearing
  • Seal PTFE
