1999-2004 Mustang SVE 8.8" 31 Spline Heavy Duty Rear Axle Kit - 3.55 Gears
Upgrade your 1999-2004 Mustang's 8.8" rear end with this SVE 31-spline heavy-duty rear axle kit with 3.55 gears to add strength and reliability! 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, and Ford Performance, this kit ensures you have the right parts to keep your Mustang rolling with confidence.

Ford Performance Traction-Lok
Included with the kit is a Ford Performance 31 spline Traction-Lok differential that optimizes 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 limits the "one-wheel wonder"! This Ford Performance Differential for 8.8" rear ends uses the same carbon fiber clutch pack used in the 2003-2004 Cobra, 2005-2014 Mustang GT, & 2007-2014 Shelby GT500 SVT Mustangs. Carbon-fiber friction plates are much more durable and are designed for higher torque over their stock counterparts. Perfect for the street or strip!

Ford Performance 3.55 Gears
These Ford Performance Mustang 3.55 gears are a great way to improve acceleration to make your Mustang faster! The kit features a set of Ford Performance 3.55 gears and a Yukon gear install kit with American-made Koyo bearings. 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.
