Spec Clutch SV82A Aluminum Flywheel - SFI Certified Lightweight Performance

The SPEC SV82A is a high-performance aluminum flywheel engineered for competitive racing applications. Precision CNC-machined to an exceptional .001" tolerance—ten times tighter than industry standards—this flywheel ensures perfect balance and a flawlessly flat bedding surface for optimal clutch disc engagement and longevity. SFI certified for safety in competitive environments.

Key Features:

• Aircraft-quality billet aluminum construction for significant weight reduction
• CNC-machined to .001" tolerance for perfect balance at high RPM
• Replaceable steel friction plate for enhanced clutch bedding and holding power
• Rebuildable design extends service life and reduces long-term costs
• SFI certification ensures safety in competitive racing applications
• Optimized moment of inertia (MOI) for improved throttle response and acceleration
• Friction-enhancing steel surface specially formulated for maximum power transfer

SPEC flywheels address the three critical factors for clutch performance: providing a consistent friction surface, delivering optimized inertia for your specific application, and maintaining true balance to eliminate power-robbing vibrations. The lightweight aluminum construction reduces rotational mass, allowing faster engine acceleration and improved throttle response—ideal for road racing, autocross, and drag racing applications where quick shifts and rapid RPM changes are essential.

The replaceable steel friction plate is manufactured from a proprietary alloy designed specifically for optimal clutch disc bedding and holding power, ensuring consistent performance even under extreme conditions. When the friction surface eventually wears, the plate can be replaced rather than purchasing an entirely new flywheel, making this a cost-effective choice for serious racers.
