This unit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub. Best for drag racing, road racing, pulling, rallye and drift.
- High clamp pressure plate
- Carbon-Graphite Friction Material
- High torque solid hub and disc assembly
- Bearing and tool kit (varies by kit)
Some of these clutch kits must be used with the Spec flywheel. Please contact us or Spec to see if the kit you are interested in needs the use of their flywheel.
