Product Description

Mustang 3.73 Gear Kit
These Ford Performance Mustang 3.73 gears are a great way to improve acceleration to make your Mustang faster! This kit fits 1986-2009 Mustang with an 8.8" rear end. The kit features a set of Ford Performance 3.73 gears, a Yukon gear install kit w/ American made Koyo bearings, a bottle of Ford Performance friction modifier, and 2 bottles of Royal Purple 75W140 gear oil. The bearing kit includes a GT500 style pinion bearing, new carrier bearings, pinion seal, ring gear bolts, pinion nut, crush sleeve, shims, and marking compound. With this kit, you can get your gear installation completed quickly and easily.

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

Royal Purple Max-Gear Oil
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 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.

Installation Note
Although the Royal Purple gear oil has friction modifier mixed in, it is still recommended that you use the bottle of Ford Performance friction modifier to supply your 8.8 rear end with the proper amount of modifier.
