Product Description

SPEC clutch kits for the MS3 are some of the highest quality performance clutch kits on the market. SPEC makes a high performance clutch option for you; whether your MS3 is a bone stock daily driver or a fully modified track beast.

Important Note: These kits are a SPEC proprietary non self-ratcheting design and must be used with a SPEC billet flywheel SZ03A-2, these will not work with any other flywheel! Advantages of these units over a factory based self-ratcheting clutch upgrade are: improved pedal feel, higher clamp load options, higher rpm capability, race-proven reliability. Installation is direct bolt-in with no other modifications necessary. If you are looking to reuse your stock or any other flywheel, check out our selection of other clutches.

These clutch kits are often built to order which usually takes 1-3 days.

SPEC Clutch Kits Include:
High clamp pressure plate
High torque hub and disc assembly
*Replacement bearings
*Alignment tool
