Premium Quality. When you're shopping for a new flywheel, you want a flywheel that is made to the highest standards for both performance and safety. SPEC Billet Steel Flywheels are machined to a .001 tolerance (other brands are only made to .01) and designed and weighted for the perfect balance and surface to complement your new clutch.
Protects Your Investment. When replacing your clutch you have two options: resurfacing your flywheel, or getting a new flywheel. Most times, getting a new flywheel is better than resurfacing, as the flywheel will dictate how well your clutch will perform, as well as how long it will last.
Rebuildable. A cheaper flywheel won't stay that way - SPEC's steel flywheels have a replaceable steel friction plate which makes this flywheel rebuildable. And this flywheel surface is also made from a special type of steel specifically designed to help your new clutch "bed in" properly and to promote superior grip - so this might just be the last flywheel you ever have to buy.
SFI Certified. If you're using this flywheel in high performance or racing applications, SFI Certification is critical so you can run your Pony at the track or strip. And it's great for peace of mind even in a daily driver - at higher RPMs, stock cast flywheels have been known to explode.
Application. This Spec Billet Steel Flywheel fits late 2001-2004 GT and Bullitt Mustangs with a six bolt main crank. This the perfect companion to your new clutch.
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.
