Jeep CJ Model 30 Front Axles

Make Sure It Fits Your Vehicle

The AMC Model 20 is the axle found in most 1976-86 CJs and 1980-91 SJs. If you need replacement parts for your rear Model 20 axle, we have them. Safe and consistent jeeping relies on properly functioning parts. Whether your rear axle is old and worn or you snapped it while off-roading, you can find everything you need at 4 Wheel Parts. Stay out on the trails with our abundance of high-quality replacement rear axle parts from leading brands such as Crown Automotive, Dana Incorporated and Omix-ADA.

Avoid Needless Delays
The stock two-piece design of the AMC 20 rear axle typically holds the flanges and shafts together using large retaining nuts at either end. Over time, wear and tear and hard riding can cause components to wear down, which can lead to hazardous situations. 4 Wheel Parts maintains a huge inventory of AMC 20 differential and rear axle mechanisms that enable your 1980–1991 SJ or 1976–1986 CJ to safely and successfully operate. Avoid mistakes, unnecessary risks and delays by exchanging your worn and malfunctioning parts for our durable replacements.

Depending on your vehicle model and year, you may have a narrow track or wide track design, possibly accompanied by an offset differential. In order to choose suitable replacements, you must know what type you require. We've taken care of the guesswork by providing a shopping method specific to your vehicle. Simply select your Jeep details from the menu, then use the AMC 20 axle diagram to view available products. The AMC 20 rear end diagram contains hyperlinked numbers next to each item that instantly redirect you to appropriate options. Looking for shafts, keys, hubs, nuts, washers, studs or inner seals? We have them, along with many additional products. Feel like you could use a hand? We're here to assist you and ensure that you locate the right product.

At 4 Wheel Parts, we work diligently to exceed your expectations. Our exclusive 90-day price match guarantee ensures that you pay fair prices, while our quick shipping gets orders to you rapidly.
