Description

SPEC Stage 4 clutch kits are solid hub versions of their Stage 3 clutches. Each hub is solid with eight rivets and the assembly is heat-treated for strength and durability. They are available in a 3, 4, and 6-puck configurations. Use a 3-puck for the lightest option or a 6-puck for the smoothest engagement. The 4-puck kit is a good compromise for both. Street-drivable in 6-puck configuration, but not street friendly due to the rigid hub.

Additional features of SPEC Stage 4 clutch kits:

* High-clamp pressure plate
* Carbon-graphite friction material
* High-torque solid hub and disc assembly
* Bearing and tool kit included
* Great for road racing, rally, drag racing, drifting, and pulling
