PRODUCT DESCRIPTION Get the best gears for your Mustangs! Ford Motorsports differential gears are factory designed to work flawlessly with your Mustang's rear differential.
Gears allow your Mustang to accelerate more quickly by multiplying the torque output of the differential and by getting the engine to the strong part of the rpm range where the engine makes the most power. The right gear will transform your Mustang into a beast!
Application: Mustang with 8.8" axle. This kit includes ring, pinion, crush sleeve, and pinion nut. Installation kits M-4210-A/B/C available seperately.
Changing gears will alter the reading of your Mustang's speedometer. Use Ford Racing M-4209ADPT-9404A on 94-04 Mustangs to correct speedometer. 2005-present Mustangs require Flash Tuner to correct speedometer such as Diablosport or SCT.
