Spec Clutch SD363F-2 Stage 3 Plus Performance Clutch Kit

The SPEC SD363F-2 Stage 3 Plus Clutch Kit is SPEC's flagship single-disc performance clutch solution, engineered for heavily modified street machines and motorsport applications that demand more torque capacity than the standard Stage 3 can provide. It delivers the ideal balance of high torque handling and everyday drivability — a combination rarely achieved at this performance level.

At the heart of the Stage 3 Plus is a full-faced carbon semi-metallic friction disc, which provides superior friction coefficient, outstanding wear life, and excellent drivability characteristics in a single package. Unlike puck-style Stage 3 discs, the full-faced design offers smoother engagement and better manageability under demanding conditions.

Key Features:

• High-clamp pressure plate for maximum clamping force and torque transfer
• Full-faced carbon semi-metallic friction disc for unparalleled life and drivability
• High-torque double-sprung hub with spring cover reliefs for flexibility and heat-treated components for strength and durability
• Bearing and alignment tool kit included for complete installation
• SFI Approved construction for added safety and confidence
• Made in the U.S.A.

Intended Driving Applications: Street, Drag Racing, Drift, Road Racing, Pulling, Autocross, Rally

The SPEC Stage 3 Plus is the go-to upgrade for high-powered builds that require a clutch capable of handling serious torque without sacrificing the pedal feel and engagement manageability needed for street use. It steps beyond the Stage 3 in both torque capacity and wear characteristics, making it the preferred choice for modified engines that have outgrown standard performance clutch options.
