When full-size GM 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 AL-RK-2A improves holding capacity in Allison 1000/2000/2400 converters 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.
NOTE:

Additional parts are required for installation of AL-RK-2A in 2006-later units:

  • For 2006 and 2007 units, the OE stator cap must be replaced with AL-WA-3.
  • For 2008-later units, measure the combined height of the OE stator cap and bearing race.
  • Units with a combined height of .482” will require replacing the OE stator cap and bearing with AL-WA-3 and AL-N-2.
  • Units with a combined height of .513” will require replacing the OE stator cap and bearing with AL-WA-4 and AL-N-2.
  • Patent No. 7,770,704
