All SPEC modular flywheels have a 6, 8, and custom 12 bolt pattern for use with a number of pressure plates. Crank pattern is 8 bolt.

Designed for High-Performance Applications: The Spec Billet Aluminum Flywheel is designed to improve acceleration by reducing rotational mass. Unlike one-size-fits-all flywheels, this flywheel is specifically tuned to the application to ensure optimum performance. Furthermore, the aluminum construction makes the flywheel lighter than the stock flywheel, making for faster revving, less drag, and quicker response time.

Precision-Machined Billet Aluminum: One of the benefits of the billet aluminum construction is its strength and lightweight. Furthermore, the precise machining to .001 tolerance guarantees the flattest seating surface possible and smooth rotational qualities. Additionally, the precision machining delivers perfect balance that helps extend engine life.

Rebuildable Steel Friction Plate: The Spec Billet Aluminum Flywheel has a rebuildable friction plate. This allows for an improved and consistent grip with regular maintenance while saving you significant money relative to buying a new flywheel. 

SFI Certified: All Spec flywheels are SFI Certified to exceed high-speed racing safety standards. This gives you confidence that the flywheel will not fail catastrophically when pushing your Mustang to its limit.

Spec Clutches and Flywheel Limited Warranty: This Spec Billet Aluminum Flywheel is warranted to be free of defects in materials or workmanship for 120 days from the date of purchase for normal use and service. Exclusions will apply.
