1979-1993 Mustang SVE 31 Spline Heavy Duty Rear Axle Kit 4 Lug - 3.73 Gears
When it's time to beef up your 1979-1993 Fox Body Mustang 8.8" rear end, look no further than this 31-Spline Heavy Duty Rear Axle Kit from LMR! SVE has taken out the guesswork in compiling this heavy-duty rear axle kit solution which packs in the performance for severe service, be it on the drag strip or the road course! Featuring core components from brands like SVE, Yukon, Ford Performance, and Royal Purple this kit ensures you have the right parts to keep your Mustang rolling with confidence.

31 Spline 4 Lug Rear Axle Conversion
These Yukon axles are stock length 31 spline with a 4x108 bolt pattern that allows the use of popular 4 lug wheels on your Fox Body Mustang. Yukon builds these axles from high-quality, 1541H forged steel that's hardened to increase torque capacity 25% over your stock axles. A set of 8 new wheel studs are included to make installation quick and easy!

Ford Performance Traction-Lok
Ford Racing Traction-Lok differentials optimize your vehicle's traction by transferring the power to both rear wheels. These limited-slip differential units use heavy plate-style clutches to ensure your engine's full power potential makes it to the ground and limit the "one-wheel wonder"! Perfect for the street or strip!

Ford Racing Friction Modifier
Ford Racing friction modifier is a specialty 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 the rear ends equipped with Ford traction-lock units.

Ford Performance 3.73 Gears
These Ford Performance Mustang 3.73 gears are a great way to improve acceleration to make your Mustang faster! 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 75W90 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.

SVE Performance 8.8 Rear Axle Differential Cover
SVE's aluminum differential cover adds strength to your differential by reducing flex in the main bearings. When your differential bearings move this allows the ring and pinion to mesh incorrectly, which in turn, creates unwanted wear and can eventually lead to the infamous gear whine/failure. This heavy-duty differential cover comes with bolts, washers, and installation instructions to ensure proper installation.

Speedometer Correction
After installation of rear gears, you will need to correct the speedometer. There are different methods to do this depending on year model.
