Spec Clutch SA403H Stage 2 Plus Performance Clutch Kit

The SPEC SA403H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than the standard Stage 2 can deliver. Bridging the gap between Stage 2 and Stage 3, this kit delivers a 15–20% higher torque capacity while preserving the smooth, street-friendly engagement feel that Stage 2 is known for. Whether you're running a modified daily driver, hitting the drag strip, or competing in autocross, the Stage 2 Plus is built to keep up.

Key Features:

• Multi-friction composite disc in a full-faced configuration — carbon semi-metallic material on one side, Kevlar on the other — for enhanced grip and excellent wear characteristics
• High-clamp pressure plate for increased clamping force to handle elevated torque output
• Double-sprung hub with spring cover reliefs for flexibility; heat-treated components for strength and long-term durability
• 15–20% higher torque capacity over the standard Stage 2 while maintaining comparable pedal feel and daily drivability
• SFI approved — meets strict safety standards for performance clutch applications
• Designed, hand-built, and tested in the U.S.A.

Kit Includes: High-clamp pressure plate, composite multi-friction carbon-Kevlar disc, high-torque sprung hub and disc assembly, release bearing, and installation tool kit.

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

The SPEC Stage 2 Plus is the ideal choice for enthusiasts who have outgrown their Stage 2 clutch but want to retain excellent street manners without jumping to the more aggressive Stage 3. Note: Some applications may require a SPEC billet flywheel — confirm compatibility before installation.
