Spec Clutch SR063H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SR063H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 kit can deliver. Bridging the gap between the Stage 2 and Stage 3, this kit provides 15–20% higher torque capacity while preserving the smooth, street-friendly engagement feel the Stage 2 is known for — making it an ideal upgrade for high-performance builds that still see daily use.

At the heart of the kit is a composite multi-friction disc in a full-faced configuration, featuring carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction design delivers excellent wear characteristics, consistent pedal feel, and strong bite across a wide range of driving conditions.

Key Features:

• High-clamp pressure plate for increased clamping force on modified engines
• Composite multi-friction disc — carbon semi-metallic on one side, Kevlar on the other
• Double-sprung hub with spring cover reliefs for drivetrain flexibility and smooth engagement
• Heat-treated hub components for long-term strength and durability
• High-torque sprung hub and disc assembly designed to handle elevated power levels
• Bearing and tool kit included for complete installation
• Designed and hand-built in the U.S.A.

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

The SR063H Stage 2 Plus is the go-to choice for drivers who need more holding capacity than a Stage 2 can offer but want to avoid the aggressive engagement characteristics of a Stage 3. It delivers the best of both worlds — enhanced torque handling with everyday drivability.
