Spec Clutch SM243-2 Stage 3 Performance Clutch Kit

The Spec Clutch SM243-2 Stage 3 Clutch Kit delivers an aggressive yet streetable performance upgrade for drivers who demand both high torque capacity and everyday drivability. Built around a carbon semi-metallic 6-puck sprung hub disc, this kit represents the proven benchmark in puck-style clutch performance — balancing engagement feel, service life, and power handling in a single assembly.

The disc hub is double sprung with spring cover reliefs for added flexibility under load, while heat-treated internal components ensure long-term strength and durability under repeated high-stress cycles. The included high-clamp pressure plate provides the clamping force necessary to handle elevated torque demands without slippage.

Key Features:

• Carbon-graphite friction material for superior heat resistance and consistent torque transfer
• 6-puck sprung hub disc with proven drivability and long service life
• Double-sprung hub with spring cover reliefs for flexibility
• High-clamp pressure plate for maximum torque capacity
• High-torque sprung hub and disc assembly
• Heat-treated components for strength and durability
• Includes release bearing and alignment tool kit
• Also available in 3-puck configuration

Intended Use:

• Street performance
• Drag racing
• Road racing
• Rallye and drift
• Pulling and autocross

The Stage 3 kit bridges the gap between daily driving and serious motorsport use, making it an ideal choice for modified street cars and dual-purpose builds that see both road and track duty. Note: Flywheel must be resurfaced or replaced prior to installation. A minimum 450-mile break-in period of primarily city and stop-and-go driving is required before full-throttle engagement or speed shifting.
