Spec Clutch SC073-2 Stage 3 Performance Clutch Kit - Street/Strip

The Spec Clutch SC073-2 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand serious torque capacity without sacrificing everyday drivability. Rated up to 495 ft-lbs of torque, this kit strikes the ideal balance between aggressive performance and a comfortable, streetable pedal feel with quick, confident engagement.

At the heart of the Stage 3 kit is a carbon semi-metallic puck disc — available in 4-puck or 6-puck configurations (6-puck is standard on most applications; 4-puck available by request). The high-torque sprung hub features a double-sprung design with spring cover reliefs for added flexibility, while heat-treated components ensure strength and durability under both low and high-stress conditions. A high-clamp billet pressure plate delivers consistent clamping force across the full range of RPM and load.

• High-clamp performance pressure plate
• Carbon semi-metallic 4 or 6-puck sprung hub disc assembly
• Release bearing
• Alignment tool

The Spec Stage 3 sits within SPEC's street/strip lineup (Stages 1–3+) and is the top recommended street-legal stage before crossing into race-only territory (Stages 4–5). It is an ideal upgrade for forced induction and high-output builds that require a clutch capable of handling serious power while remaining livable in daily driving conditions.
