Spec Clutch SZ483F Stage 3 Plus High-Performance Clutch Kit

The SPEC SZ483F Stage 3+ Clutch Kit is the flagship street/strip upgrade for high-powered applications that demand maximum torque handling with a manageable, street-friendly engagement. Engineered for heavily modified engines that have outgrown the Stage 3, the Stage 3+ steps up torque capacity to 477 ft-lbs at the flywheel while maintaining the daily drivability that makes it a versatile choice for both road and track.

At the heart of the kit is a full-faced carbon semi-metallic friction disc — a material chosen for its exceptional combination of friction coefficient, wear resistance, and smooth engagement feel. The disc assembly features a double-sprung hub with spring cover relieves for added flex and shock absorption, along with heat-treated components throughout for long-term strength and durability.
