Spec Clutch SP69A Aluminum Flywheel SFI Certified CNC Billet

The SPEC SP69A is a billet aluminum flywheel CNC-machined to an exceptional .001-inch tolerance — ten times tighter than the industry standard of .010 inches. This precision ensures perfect rotational balance and a perfectly flat bedding surface for the clutch disc, reducing vibration and maximizing clutch performance in both street and competition applications. The SP69A carries full SFI certification, making it approved for use in sanctioned racing environments.

Key Features:

• Aircraft-quality billet aluminum construction for reduced rotating mass and improved throttle response
• CNC machined to .001-inch tolerance — 10x tighter than the industry standard
• Replaceable steel friction plate made from a friction-enhancing alloy specially formulated for optimum clutch bedding and holding power
• Rebuildable design — replace the friction surface without replacing the entire flywheel
• SFI certified for use in sanctioned competition
• Zero dimensional runout eliminates engine-damaging vibrations and power-robbing harmonics
• Optimized Moment of Inertia (MOI) engineered for maximum power transfer and acceleration

The flywheel is the single most important component in the clutch system. It provides the friction surface for the clutch disc, determines rotational inertia based on its weight, and must maintain true balance at all RPM ranges. SPEC engineers invest heavily in research and development to optimize flywheel dimensions and weights across all driving and racing disciplines, allowing the SP69A's aluminum construction to deliver a lightweight inertia profile ideal for high-revving, performance-oriented applications.

The SPEC SP69A aluminum flywheel is designed for drivers who demand precision, durability, and the confidence of SFI-certified safety — whether on the track or the street.
