Product Description

Here at LatemodelRestoration.com we know what it takes to install a new set of rear end gears into your Mustang, so we put it all together for you to take out all of the guesswork!

Not only do we include the hardware (rear end gears, bearings, shims), but we also include all of the software (gasket, seals, marking compound, gear oil, friction modifier) needed to do the job the right way!

Ford Racing rear end/ring and pinion gears improve acceleration and performance on your Mustang GT or V6! When its time to replace your stock gears go with the best! Trust the proven name, use Ford Racing’s heavy duty rear axle ring and pinion set. Pinion nut included.

Ford Racing Bearing Kits include the 2012 GT500 style inner pinion bearing. This is one beefy bearing & is the perfect upgrade for your Mustang. All needed bearings, shims, bolts, nuts, & pinion seal are included in this awesome kit!

Royal Purple Max-Gear gear oil is an ultra-tough automotive gear oil. It’s designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes Mustang gears run smoother, quieter, cooler and longer without overhauls. Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.

Ford Racing friction modifier is a specially formulated additive to provide smooth operation of clutch-type limited-slip differentials. 1 bottle of friction modifier is required when changing the gear oil in rear ends equipped with Ford traction-lock units.

Now, everything you need to install rear gears in your Mustang in one package!

Kit includes:
1 Ford Racing Performance Parts 3.73:1 gearset
1 Ford Racing M-4210-B2 bearing kit (includes GT500 pinion bearing & race, carrier bearings, pinion seal, ring gear bolts, pinion nut, crush sleeve, shims, and marking compound)
1 bottle of Ford Racing Performance Parts Friction Modifier
2 bottles of Royal Purple 85w140 gear oil

This kit works great in all Ford Mustang 8.8 rear ends for better performance and acceleration.

**Although the Royal Purple gear oil contains friction modifier, we highly recommend including the Ford Racing friction modifier along with the gear oil when refilling your rear end.**
