Spec Clutch SN501-2 Stage Performance Clutch Kit - 1

The SPEC SN501-2 Stage 1 Clutch Kit is a high-performance upgrade engineered for drivers who demand more from their drivetrain without sacrificing everyday drivability. Built around an integrally molded carbon Kevlar-based organic friction lining, this kit delivers smooth, progressive engagement with outstanding service life — ideal for street driving and high-demand performance applications alike.

The friction disc features an integrally bonded steel backing that provides structural rigidity under elevated clamp loads and operating temperatures. The hub assembly is double-sprung with spring cover reliefs for enhanced rotational flexibility, while heat-treated internal components ensure long-term strength and durability under repeated high-stress cycling.

Key Features:

• Carbon Kevlar-based organic lining — smooth engagement with excellent wear resistance
• High clamp pressure plate — increased clamping force over stock for higher torque capacity
• Steel-backed, multi-compound woven organic disc material — durability under heat and load
• Double-sprung, high-torque hub and disc assembly — improved flexibility and vibration damping
• Heat-treated hub components — added strength and fatigue resistance
• Torque capacity: 300 ft/lbs
• Includes bearing and alignment tool kit for straightforward installation

Intended Driving Applications: Street, Drag, Drift, Road Race, Rallye, Pulling, Autocross
