31 Spline 4-Lug Rear Axle Kit with a Yukon Dura Grip Positraction Differential for all 1979-1993 Mustangs with a 8.8" Rear End.This kit includes high-quality rear axle shafts from Yukon Gear & Axle. Aftermarket axle shafts can mean the difference between first and last in competition applications in addition to offering higher strength and longer life in street driven vehicles. Yukon Gear & Axle uses only the highest quality steel and chrome-moly alloys for their axle shafts and the latest in heat treating and manufacturing technologies. Yukon Gear & Axle has the strength you need for on or off the race track.
Also includes a Yukon Dura Grip positraction differential that features a 4-spring, clutch style limited slip which traces its roots back to the muscle car positractions of the 1960's. Yukon Dura Grips provide great traction and strength, without being too aggressive for street use. The Yukon Dura Grip uses a nodular case and forged 4320 internals for added strength along with composite clutches for high performance and long life. Yukon Dura Grips are fully rebuildable, allowing for repair or modification without the cost of purchasing a new unit. All Yukon Dura Grips are assembled in the USA.
