•No one does 8.8" gears better than Ford Performance...stronger and quieter.
•The 8.8" rear end has been the standard in performance since its introduction in the Mustang in 1986 and Ford Performance is the manufacturer of choice when it's time to hop-up your axle.
•Made in the United States at Ford's Sterling Axle Plant (competitors in this price range are primarily produced in China)
•OEM quality - our superior surface finish, hardening, and manufacturing consistency provide the strongest and quietest 8.8" gears in the market! These are the same units that have 100,000 mile warranties in our production cars. Higher quality gears means more satisfied customers!
•Race Proven - Ford Performance 8.8" gears are the choice of championship road racing and drag racing teams including Multimatic Motorsports and Kurgan Motorsports.

When your plans call for an 8.8" gear, look for the only brand good enough to wear the Ford oval!
