Spec Clutch SF203 Stage 3 Performance Clutch Kit

The SPEC SF203 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand high torque capacity without sacrificing everyday drivability. Designed for drivers who need an aggressive yet streetable engagement, this kit strikes a balance between performance and comfort with a relatively comfortable pedal feel and quick, confident engagement.

At the heart of this kit is a carbon semi-metallic puck disc — available in a 4-puck or 6-puck configuration (6-puck is standard on most applications; 4-puck available upon request). The sprung hub is double-sprung with spring cover reliefs for added flexibility, while heat-treated internal components deliver the strength and durability required for both street and race use.

Key Features:

• High-clamp performance pressure plate for increased torque capacity
• Carbon semi-metallic friction material — 6-puck sprung hub disc (4-puck available)
• Double-sprung hub with spring cover reliefs for flex and NVH reduction
• Heat-treated components for long-term strength and durability
• High-torque sprung hub and disc assembly
• Bearing and installation tool kit included

Intended Driving Applications:

• Street / Daily Driven
• Drag Racing
• Road Racing
• Drifting
• Rallye
• Pulling
• Autocross

The SPEC Stage 3 is positioned as a high-performance street and competition clutch — suited for modified vehicles that need more than a stock or mild upgrade can offer, but still require reliable daily driveability. It is part of SPEC's street/strip lineup, which spans Stage 1 through Stage 3+, before stepping into dedicated race-only Stage 4 and Stage 5 configurations.
