Spec Clutch SB333H Stage 2 Plus Performance Clutch Kit

The SPEC SB333H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can deliver. Bridging the gap between the Stage 2 and Stage 3, this kit offers the familiar daily-drivable engagement feel of the Stage 2 while delivering a 15–20% higher torque capacity — making it the ideal step up for street-driven vehicles with performance modifications.

At the heart of the kit is a composite multi-friction disc in a full-faced configuration, featuring carbon semi-metallic material on one side and Kevlar® on the other. This dual-material design provides excellent wear resistance, smooth engagement, and consistent performance across a wide range of driving conditions.

Key Features:

• High-clamp pressure plate for increased clamping force and torque holding capacity
• Hybrid carbon-graphite and Kevlar® friction material for durability and smooth engagement
• Double-sprung hub with spring cover reliefs for added flexibility and vibration damping
• Heat-treated components for long-term strength and durability
• High-torque sprung hub and disc assembly for reliable power transfer
• Bearing and tool kit included for a complete installation

Intended Use: Street, Drag Racing, Road Racing, Rally, Autocross, Pulling, and Drifting

The SPEC Stage 2 Plus is the go-to clutch upgrade for enthusiasts who want real performance gains without sacrificing the drivability and pedal feel of a stock-like clutch system.
