Description

SPEC Stage 2 clutch kits are designed for street, drag race, pulling, and autocross use. They feature segmented or full-faced Kevlar® discs with steel backings. These linings deliver excellent drivability like SPEC Stage 1 clutches, but with slightly longer life and higher torque capacity. The hubs are double-sprung with spring cover reliefs for flexibility and heat-treated components for strength and durability. Nearly a thousand models are available; order the kits recommended for your vehicle.

Additional features of SPEC Stage 1 clutch kits:

* High-clamp pressure plate
* Pure Kevlar® friction material
* High-torque sprung hub and disc assembly
* Bearing and tool kit included (where applicable)
