Spec Clutch SU003H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SU003H Stage 2 Plus Clutch Kit is engineered for modified engines that have surpassed the torque threshold of a standard Stage 2 clutch. Bridging the gap between the Stage 2 and Stage 3, this kit delivers the familiar, street-friendly engagement feel of the Stage 2 while providing a 15–20% higher torque capacity — rated up to 440 ft-lbs — for builds that demand more.

Key Features:

• Multi-friction disc in a full-face configuration with carbon semi-metallic material on one side and Kevlar on the other for optimized grip and wear resistance
• High-clamp pressure plate for increased clamping force on modified applications
• Double-sprung hub with spring cover reliefs for drivetrain flexibility and smooth daily engagement
• Heat-treated hub components for long-term strength and durability
• High-torque sprung hub and disc assembly included
• Release bearing and installation tool kit included

The Stage 2 Plus retains excellent daily drivability and wear characteristics, making it a practical choice for street-driven vehicles that also see occasional track, drag strip, autocross, or rally use. Suitable driving applications include: Street, Drag, Road Race, Rally, Pulling, and Autocross.
