Spec Clutch SC553F Stage 3 Plus Clutch Kit

The SPEC SC553F Stage 3 Plus Clutch Kit is engineered for heavily modified street and race engines that have exceeded the torque threshold of the standard Stage 3. As SPEC's flagship performance clutch stage, the Stage 3 Plus delivers a rare combination of high torque capacity and daily drivability — offering a more manageable and forgiving engagement than a full race clutch while still handling the demands of serious power builds.

At the core of the Stage 3 Plus is a full-faced carbon semi-metallic friction disc, which provides an excellent balance of friction coefficient, wear life, and drivability in a single package. The hub is double-sprung with spring cover reliefs for added flexibility, while heat-treated internal components deliver long-term strength and durability under extreme loads. All SPEC clutch assemblies are designed, hand-built, and tested in the USA.

Key Features:

• High-clamp pressure plate for increased torque holding capacity
• Full-faced carbon semi-metallic friction material for superior wear life and friction coefficient
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement
• Heat-treated hub components for strength and long-term durability
• Complete kit includes pressure plate, disc, bearing, and installation tool kit
• Designed, hand-built, and tested in the USA

Intended Use: Street, Drag Racing, Drift, Road Racing, Autocross, Pulling, Rally

The SPEC Stage 3 Plus is the ideal upgrade for high-powered builds that demand race-level torque capacity without sacrificing the street manners needed for everyday driving.
