Spec Clutch SM881-3 Stage Performance Clutch Kit - 1 Organic Carbon Kevlar

The Spec Clutch SM881-3 is a Stage 1 performance clutch kit engineered for street-driven vehicles that also see occasional track use. Built around an integrally molded carbon Kevlar-based high-performance organic lining, this clutch delivers smooth, confidence-inspiring engagement combined with excellent service life under demanding conditions.

The friction disc uses a steel-backed, multi-compound woven organic material construction that maintains integrity under high clamp loads and elevated temperatures. The sprung hub is double-sprung with spring cover reliefs for added drivetrain flexibility, while heat-treated internal components provide lasting strength and durability.

Featuring a high-clamp pressure plate and a 216mm (8.5 in.) disc diameter, this kit is a direct-fit replacement that upgrades holding capacity beyond OEM levels without sacrificing daily-driver pedal feel. The kit also includes a bearing and installation tool kit for a complete installation package.
