Maximum Durability for Your Jeep CJ8 AMC 20 Rear Axle

The AMC 20 rear axle is a defining feature of the 1981-1985 Jeep CJ8. Since the original two-piece axle shafts are a known weak point, we provide specialized solutions to reinforce your drivetrain for both street and trail use. Our inventory includes all specific components to keep your rear end running strong.

Trusted Brands: Dana Spicer, Crown and Dorman

For a professional rebuild, we stock high-quality ring and pinion sets along with bearing and shim kits from Crown Automotive. To eliminate axle failure, we offer one-piece axle shaft kits from RT Off-Road that provide significantly more strength than the factory setup. Precision-fit wheel hubs, differential covers and all necessary oil seals & accessories from Crown Automotive, Dorman and Dana Spicer complete our drivetrain portfolio.

Expert Support for Your AMC 20 Build

Correct differential setup is key to a quiet and long-lasting axle. Our outstanding customer service is here to help you select the right gear ratios and replacement parts. With our fast shipping, your AMC 20 components will arrive quickly, getting your Jeep CJ8 Scrambler back on the road with reliable power delivery.
