Spec Clutch SF053H Stage 2 Plus Performance Clutch Kit

The SPEC SF053H Stage 2 Plus Clutch Kit is engineered for modified engines that have outgrown the torque capacity of a standard Stage 2 clutch. Bridging the gap between Stage 2 and Stage 3, this kit delivers the street-friendly engagement feel and smooth drivability of the Stage 2 while offering a 15–20% higher torque capacity — rated at up to 425 ft-lbs — making it the ideal upgrade for high-performance builds that still see regular street use.

At the heart of this kit is a composite multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction material delivers excellent wear characteristics, consistent engagement, and the higher clamping force needed for boosted or heavily modified powerplants. The double-sprung hub features spring cover relieves for added flexibility and heat-treated components for long-term strength and durability.

Key Features:

• High-clamp performance pressure plate for increased torque holding
• Composite multi-friction disc — carbon semi-metallic / Kevlar full-faced configuration
• 15–20% higher torque capacity over the standard Stage 2 kit
• Double-sprung hub with heat-treated components for strength and durability
• Excellent wear characteristics for extended service life
• Includes bearing and tool kit for installation
• Designed and hand-built in the U.S.A.

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

The SPEC SF053H is the go-to solution for enthusiasts who need more than a Stage 2 can offer but want to preserve daily drivability without stepping up to the harsher engagement of a full Stage 3 clutch.
