Spec Clutch SZ153H Stage 2 Plus Performance Clutch Kit

The SPEC SZ153H 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 the Stage 2 and Stage 3, this kit provides a 15–20% higher torque capacity while preserving the smooth, street-friendly engagement feel that the Stage 2 is known for.

At the core of the Stage 2 Plus is a multi-friction composite disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction design delivers excellent wear characteristics, consistent bite, and reliable performance across a wide range of demanding driving conditions.

Key Features:

• High-clamp performance pressure plate for increased clamping force
• Full-faced composite multi-friction disc — carbon semi-metallic on one side, Kevlar on the other
• Double-sprung hub with spring cover reliefs for flexibility and heat-treated components for strength and durability
• High-torque sprung hub and disc assembly
• SFI approved clutch kit and flywheel
• Bearing and installation tool kit included

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