Spec Clutch SZ703F Stage 3+ Clutch Kit Carbon Semi-Metallic Full-Face

The SPEC SZ703F Stage 3 Plus Clutch Kit is SPEC's flagship street/performance clutch stage, engineered for high-powered vehicles that demand serious torque capacity without sacrificing daily drivability. Featuring a carbon semi-metallic full-face friction disc, the Stage 3+ delivers exceptional friction coefficient, outstanding service life, and smooth, manageable engagement in a single complete package.

The hub assembly is double-sprung with spring cover reliefs, providing flexibility under load while heat-treated internal components ensure long-term strength and durability. The kit pairs a high-clamp pressure plate with the carbon full-face disc for a significant torque capacity upgrade over stock and lower Stage clutches, while retaining street-friendly engagement characteristics.
