All SPEC modular flywheels have a 6, 9, and custom 12 bolt pattern for use with a number of pressure plates. Crank pattern is 6 bolt.
Designed for Street and Track Applications: The Spec Billet Steel Flywheel is specially tuned to perform based on how each specific application reacts to changes in rotational mass. This ensures that the flywheel is able to deliver maximum performance. Additionally, the flywheel is precision-machined to deliver perfect balance. Furthermore, the steel construction is ideal for street applications as they lose fewer RPMs when shifting.
Precision-Machined Billet Steel: The Spec Billet Steel Flywheel is machined to the tightest tolerances at .001 machine tolerance. This ensures a flat seating surface for the smoothest rotation. Additionally, the high-quality steel ensures strength, toughness, and durability for long service.
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 Steel 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.

Technical Note: This SPEC Billet Steel Flywheel is designed for the Mustang GT's with a six bolt main. 2001 Mustangs with production date after 06/01 have a six bolt main. Please check with your Ford dealer to determine if you have a 6 bolt or an 8 bolt main.
Please Note: Romeo built engines have 6 bolt cranks and Windsor built engines have 8 bolt cranks. If the 8th character in the VIN is an "X" its a Windsor block, if the 8th character in the VIN is a "W" it is a Romeo block. There is an exception to that rule as the 2001 Bullitt Edition Mustang feature a Romeo built engine. If unsure please check with your Ford dealer to determine if you have a 6 or an 8 bolt main.
Superlite Option: Drops the steel flywheel weight from 21 lbs to 16.9 lbs.
