Premium Quality. By choosing a premium quality flywheel like a SPEC Billet Steel flywheel for your Mustang GT, you'll enjoy driving it more and also have more peace of mind. SPEC flywheels are made to the highest standards for both performance and safety. These flywheels are 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.

Please note that SPEC part# SF46S is the same as SPEC part# SF64S.

    Rebuildable, but good luck finding the new surface

    I LOVE American Muscle, and I ordered this flywheel back in 2012 specifically because it stated it was rebuildable. Unfortunately, nobody sells the replacement friction plate kit except SPEC. SPEC charges astronomical shipping prices. Would sure love AM to carry this! I honestly would have bought a different flywheel...lightweight over the rebuildable if I knew I would have to pay nearly as much after shipping for the new surface with SPEC. I'd go aluminum in hindsight and save the weight...at least until the new surface is available on AM!

    Spec Steel Flywheel

    Although this is the part number I ordered and received, it's not the same flywheel. Mine did not have the replaceable clutch surface plate. I called Spec to verify the pressure plate alignment dowels, as they appeared too big for the pre-drilled holes, but put the pins in the freezer and heated the holes, and with the help of a large hammer, inserted them with no problems. It would have been nice to have this info with the product.
