Spec Clutch SA60A Aluminum Flywheel SFI Certified Billet

The Spec Clutch SA60A is a billet aluminum flywheel precision CNC-machined to an industry-leading .001-inch tolerance — ten times tighter than the industry standard of .010. This exceptional precision guarantees a perfectly flat clutch disc seating surface and true rotational balance at high RPM, eliminating the dimensional runout that causes engine-damaging vibration and power loss. All SPEC flywheels carry SFI certification, making them suited for competitive and high-performance driving environments.

Key Features:

• CNC-machined from aircraft-quality billet aluminum to a .001-inch tolerance — 10x tighter than industry standard
• SFI certified for use in sanctioned racing and high-performance applications
• Rebuildable design with a replaceable steel friction plate, formulated for optimum clutch bedding and holding power
• Aluminum construction delivers approximately 50% weight reduction compared to a stock steel flywheel, enabling faster revving and reduced engine drag
• Optimized Moment of Inertia (MOI) engineered by SPEC for specific driving environments and power characteristics
• Provides a consistent, friction-enhancing surface for reliable clutch disc engagement
• Designed and manufactured in the USA

The SA60A aluminum flywheel is ideal for performance street, drag, drift, road racing, time attack, and autocross applications where reduced rotating mass is a priority. By reducing flywheel weight, the SA60A allows the engine to rev more freely, decreases drivetrain drag, and improves throttle response — all without sacrificing the precision balance and surface quality critical to clutch longevity and performance.
