Spec Clutch SB283H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SB283H 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 the street-friendly engagement and smooth drivability of the Stage 2 while offering a 15–20% higher torque capacity — making it an ideal upgrade for performance builds that haven't fully crossed into race-only territory.

The Stage 2 Plus disc uses a full-faced, multi-friction composite design with carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction surface delivers strong bite and excellent wear resistance across a wide range of operating conditions. The hub is double-sprung with spring cover reliefs for flexibility, while heat-treated internal components ensure long-term strength and durability under high-load driving.

Key Features:

• High-clamp performance pressure plate for increased torque holding
• Full-faced multi-friction disc — carbon semi-metallic on one side, Kevlar on the other
