Spec Clutch SP153H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SP153H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can provide. Bridging the gap between the Stage 2 and Stage 3, this kit delivers a 15–20% higher torque capacity while preserving the smooth, familiar engagement feel of the Stage 2 — making it an ideal upgrade for high-output street and track builds that still require daily drivability.

Friction Disc: The Stage 2 Plus features a multi-friction disc in a full-faced configuration with carbon semi-metallic material on one side and Kevlar® on the other, providing strong holding power, excellent wear characteristics, and progressive engagement.

Key Features:

• Multi-friction disc — full-faced carbon semi-metallic / Kevlar® composite construction
• High-clamp pressure plate — increased clamping force for higher torque loads
• Double-sprung hub — spring cover reliefs for flexibility; heat-treated components for strength and durability
• High-torque sprung hub and disc assembly — designed for modified, high-output powerplants
• Bearing and tool kit included — everything needed for a complete installation
• SFI approved — meets SFI safety standards
• Designed, hand-built, and tested in the U.S.A.

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

The SP153H is part of SPEC's proven lineup of single-disc performance clutch kits, developed and refined through real-world motorsports competition. For drivers who have outgrown their Stage 2 clutch but want to retain streetable drivability, the Stage 2 Plus delivers the ideal balance of performance and everyday usability.
