Product Description

This is the only completed performance Clutch Cartridge on the market, consisting of all parts to complete the assembly, including;
  • bearings
  • clutch shaft
  • clutch pressure plate
  • springs
  • pins and ball
  • keyway
  • m14 nut 
  • all related bolts washers and hardware 
  • pads
  • large clutch gear
 Advanced features include:
  • sealed inner bearings with plain thrust bearing
  • Ultra low profile external spring layout
  • simplified installation and adjustment 
  • slotted and drilled pressure plate and flywheel


  1. Clean and degrease the surfaces where the clutch pads ride for optimal performance.
  2. Stack one small black spacer and 5 disc springs (alternate direction on each spring) on each of the 4 spring posts on the spring carrier (part with the RDM logo on the front).
  3. Assemble the Clutch plate onto the spring carrier, the springs go into the 4 pockets.
  4. Assemble the large washer with 4 holes in the face onto the spring carrier, the lip faces away from the springs.
  5. Place the thin bearing into the clutch shaft/flywheel followed by the large ring gear and clutch pads.
  6. Bolt the two assemblies together using the M5 Bolt, notice only 4 holes are tapped the others are spares but are not pre tapped.
  7. Feed a yellow bolt into the center of the clutch plate, feed the ball bearing and pin into the clutch shaft with some grease.
  8. Feed bearings in, in some cases the large thin washer is used to space out the bearing on the clutch flywheel side, it would go in before the bearing.
  9. Insert clutch assembly, Install Key, Sprocket, and tighten the M14 nut with a 19mm or ¾” sprocket.
  10. To adjust spring preload, install more “bolt shortening shims” under the spring stacks, also adjust pin length with these same shims under the yellow bolt in the clutch plate.
