Spec Clutch SC75S Steel Flywheel

The Spec Clutch SC75S Steel Flywheel is precision-engineered from high-carbon billet steel to deliver exceptional performance and reliability in demanding applications. Manufactured to an unprecedented 0.001" tolerance—ten times tighter than the industry standard of 0.010"—this flywheel ensures perfect balance and a flawlessly flat bedding surface for optimal clutch disc engagement and longevity.

Key Features:

• CNC-machined from high-carbon billet steel for maximum strength and durability
• Precision manufactured to 0.001" tolerance for perfect balance at high RPM
• SFI certified for competitive racing safety standards
• Replaceable steel friction plate for extended service life and easy rebuilding
• Friction-enhancing surface specially formulated for superior clutch bedding and holding power
• Optimized weight and MOI (moment of inertia) for improved power transfer and acceleration
• Eliminates dimensional runout to prevent engine-damaging vibrations

SPEC flywheels are engineered with extensive R&D to provide the ideal combination of weight, balance, and friction characteristics. The steel construction offers medium weight inertia suitable for various racing applications, while the replaceable friction plate ensures long-term performance and cost-effective maintenance. Whether you're building a street performance vehicle or a dedicated race car, the SC75S delivers the precision and consistency demanded by serious enthusiasts.
