Spec Clutch SZ943 Stage 3 High-Performance Clutch Kit

The SPEC SZ943 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand serious torque capacity without sacrificing daily drivability. Featuring a comfortable pedal feel and quick, precise engagement, the Stage 3 delivers an aggressive but streetable performance upgrade over stock and entry-level aftermarket clutches.

At the heart of the kit is a carbon semi-metallic puck disc — available in either a 4-puck or 6-puck configuration (6-puck is standard on most applications; 4-puck can be specified at time of ordering) — paired with a high-torque sprung hub and disc assembly that has established itself as the benchmark in puck clutch drivability, longevity, and torque capacity. The high-clamp pressure plate ensures maximum clamping force for consistent, confident power transfer under both street and race conditions.

Kit Includes:

• High-clamp performance pressure plate
• Carbon semi-metallic 4 or 6-puck sprung hub disc assembly (6-puck standard)
• Release bearing
• Installation tool kit

Key Features:

• Carbon semi-metallic friction material for excellent bite, wear resistance, and torque capacity
• High-torque sprung hub design for smooth power transfer and reduced driveline shock
• Good wear characteristics under both low and high stress usage cycles
• Designed to handle street, strip, and track abuse
• Made in the U.S.A.

Ideal Driving Applications: Street, Drag Racing, Drift, Road Racing, Rallye, Pulling, Autocross

The SPEC Stage 3 is the go-to choice for performance enthusiasts running forced induction, aggressive camshaft profiles, or other high-output engine modifications who need a clutch that can keep up — both on the street and at the track.
