Spec Clutch SB024 Stage 4 Performance Clutch Kit

The Spec Clutch SB024 Stage 4 Clutch Kit is engineered for heavily modified, high-output engines where maximum torque capacity, instantaneous engagement, and reduced rotational mass are critical. This is a purpose-built competition clutch designed for drivers who demand uncompromising performance on the track.

Key Features:

• Solid 8-Rivet Hub Design: A solid hub with eight rivets replaces the sprung hub found in lower stages, eliminating flex and delivering direct, immediate power transfer
• Heat-Treated Assembly: The hub and carrier assembly are heat-treated for enhanced strength and long-term durability under extreme operating conditions
• High-Clamp Pressure Plate: Increased clamping force handles the elevated torque demands of heavily modified engines
• Carbon Semi-Metallic Friction Discs: Available in 3, 4, or 6-puck configurations to suit specific power levels and driving disciplines
• Complete Kit: Includes pressure plate, friction disc, release bearing, and installation tool kit for a straightforward installation

Intended Use: Drag Racing, Drifting, Road Racing, Rallye, Pulling, and Circle Track

Note: Due to the solid hub construction and high-clamp pressure plate, the Stage 4 clutch produces a harsh, aggressive engagement that is not recommended for street or daily driving use.
