Spec Clutch SZ033F-2 Stage 3 Plus Performance Clutch Kit

The SPEC SZ033F-2 Stage 3 Plus Clutch Kit is SPEC's flagship performance clutch stage, engineered for high-powered street and competition vehicles that demand strong holding power without sacrificing everyday drivability. Built around a carbon semi-metallic full-face friction material, the Stage 3+ delivers exceptional friction coefficient, longevity, and consistent engagement characteristics in a single complete package.

The disc assembly features a double-sprung hub with spring cover reliefs for enhanced flex and vibration damping, paired with heat-treated components throughout for maximum strength and fatigue resistance. The high-clamp pressure plate ensures a secure transfer of power under demanding conditions, making this kit equally at home on the street or at the track.

Rated at 448 lb-ft torque capacity, the SZ033F-2 is well-suited for modified and forced-induction applications. Note: This kit does not include a flywheel and must be used with the SPEC billet flywheel (SPEC part #SZ03A-2). Designed and hand-built in the U.S.A.
