Your rear axle and differential shouldn’t be overlooked when you’re building a vehicle for more horsepower and torque, and sometimes a tired rear axle assembly isn’t going to be up to the job of handling that extra twist and power. A remanufactured rear axle assembly from ATK is the perfect way around that problem. The remanufacture process at ATK is thorough and precise, with quality and design specs that are more stringent than from the factory. ATK remanufactured rear axle assemblies are covered by a 36 month warranty. 

Performance Benefits & Key Features

Let’s face it: going with a rear axle assembly from a salvage yard is always going to be a roll of the dice, at best. At ATK, every differential is reverse engineered and inspected so that technicians can find any factory defect or damage and address it. Differentials and rear axle assemblies are available for 2WD or 4WD applications, with final drive ratios from 3.23 to 4.10. Rear axles are available in positrac or standard configuration and 10-bolt 7.5”, 8.5, 8.6”, 10.5” or `11.5” differential sizes. 

Fitment, Compatibility & Applications 

ATK remanufactured rear axle assemblies are a fit for Chevy Tahoe, Chevy Silverado, GMC Sierra, GMC Denali, Chevy Astro, GMC Safari, Buick Rainier, Isuzu Ascender, Chevy Avalanche, GMC Yukon, Chevy Blazer, GMC Jimmy, Oldsmobile Bravada, Chevy Trailblazer and Cadillac Escalade models (1500 rating, not 2500s), with 4WD, AWD or 2WD drivetrains. Core returns are accepted, provided that the gear ratios of rear and front axles match (for 4WDs), the unit is filled with fluid, backing plates and axle shafts are intact and the old axle is equipped for disc brakes. ATK has remanufactured rear axle assemblies for models ranging from the late 1980s through 2013. Don’t take chances with a used rear axle assembly - a remanufactured axle assembly from ATK can take the guesswork out of the game so you can move forward with confidence on your upgrade or repair.
