Spec Clutch SN463H Stage 2 Plus Performance Clutch Kit

The SPEC SN463H Stage 2 Plus Clutch Kit is engineered for modified engines that have outgrown the torque capacity of the standard Stage 2, but don't require the full aggression of a Stage 3. Bridging the gap between these two stages, the Stage 2 Plus delivers the smooth daily-drivability and familiar engagement feel of the Stage 2 while offering a 15–20% higher torque capacity.

At the heart of the kit is a full-faced, multi-friction composite disc combining carbon semi-metallic material on one side and Kevlar® on the other — a configuration that balances grip, longevity, and streetability. The hub is double-sprung with spring cover reliefs for added flexibility, and all critical components are heat-treated for long-term strength and durability.

Key Features:

• High-clamp pressure plate for increased clamping force
• Full-faced multi-friction disc — carbon semi-metallic / Kevlar® composite material
• Double-sprung high-torque hub with spring cover reliefs for flexibility
• Heat-treated components for strength and durability
• Bearing and installation tool kit included
• 15–20% higher torque capacity over the standard Stage 2

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

The SPEC SN463H is a bolt-in performance upgrade for drivers seeking a meaningful torque capacity increase without sacrificing the street manners that make a clutch livable day to day.
