Spec Clutch SZ603F Stage 3 Plus Performance Clutch Kit

The SPEC Stage 3 Plus (Stage 3+) Clutch Kit is the flagship performance clutch solution for heavily modified street and race engines that demand torque capacity beyond what the standard Stage 3 can deliver. Engineered to balance maximum power handling with real-world drivability, the Stage 3+ offers a more manageable and friendly engagement than a pure race clutch, making it a versatile choice for high-powered builds that still see street duty.

Key Features:

• Carbon semi-metallic full-face friction material — delivers exceptional lifespan, friction coefficient, and drivability in a single package
• High-clamp pressure plate — designed to hold elevated torque loads without slippage
• High-torque sprung hub and disc assembly — double-sprung hub with spring cover reliefs for flexibility and heat-treated components for lasting strength and durability
• Bearing and tool kit included — everything needed for a complete clutch replacement
• Improved wear characteristics over the Stage 3 for longer service life under demanding conditions

Intended Use:

• Street Performance
• Drag Racing
• Drifting
• Road Racing
• Pulling
• Autocross & Rally

The SPEC SZ603F Stage 3+ kit is ideal for drivers who need race-level torque capacity without sacrificing the pedal feel and daily manageability required for street use. This kit is proudly manufactured in the USA.
