Spec Clutch SS95A Billet Aluminum Flywheel SFI Certified - 1.1

The Spec Clutch SS95A is a precision-engineered billet aluminum flywheel designed for high-performance and racing applications. CNC machined to an industry-leading .001-inch tolerance—ten times tighter than the industry standard of .010 inches—this flywheel delivers exceptional rotational balance, a perfectly flat clutch seating surface, and long-term drivetrain reliability. It carries SFI 1.1 certification, making it suitable for competitive and sanctioned racing environments.

The flywheel plays a critical role in overall clutch system performance, fulfilling three essential functions: providing a consistent, friction-enhancing surface for the clutch disc; contributing the correct rotational inertia to optimize acceleration and drivability; and maintaining true rotational balance at all RPM levels to eliminate harmful vibrations and power loss.

Constructed from aircraft-quality billet aluminum, the SS95A offers a significant weight reduction compared to stock steel flywheels, resulting in faster engine revving, reduced drivetrain drag, and quicker throttle response. The unit is fully rebuildable and features a replaceable steel friction plate specially formulated to maximize clutch bedding and holding power, extending the service life of both the flywheel and clutch disc.
