AMC Axle Parts & Upgrades

AMC axles, most notably the iconic Model 20 rear axle, powered classic Jeep CJ models, full-size Jeeps, and other AMC/Jeep vehicles from the mid-1970s through the 1980s, delivering reliable performance for off-road enthusiasts and daily drivers alike. Known for their durable 8.875-inch ring gear design—often compared favorably to Dana axles—these axles remain popular today thanks to a strong aftermarket support for upgrades. Browse a comprehensive selection of high-quality AMC axle parts, including precision bearings, heavy-duty axle shafts, ring and pinion gear sets in various ratios, and advanced traction devices like lockers, to help you rebuild, strengthen, or customize your AMC-equipped Jeep for maximum durability and performance.
