AMC 20 Ring and Pinion Gears

AMC 20 ring and pinion gears are available in ratios: 2.73, 3.07, 3.31, 3.54, 3.73, 4.10, 4.56, and 4.88. Carrier breaks: 2.73-down and 3.07-up. These gear sets enable precise regearing of the durable Model 20 rear axle in 1976-1986 Jeep CJ5, CJ7, CJ8, and similar AMC/Jeep applications, allowing you to tailor performance—milder ratios like 3.73 suit mixed street and light off-road driving with stock or modest tires, while 4.10 provides a great balance for 31-33" tires and everyday use, and higher options like 4.56 or 4.88 deliver superior low-end torque and crawl capability for aggressive trails with larger tires. Proper carrier selection based on the breaks ensures compatibility and strength during install. Browse a wide variety of AMC 20 ring and pinion gears to combine with installation kits, precision bearings, heavy-duty shafts, and traction devices for a complete upgrade that enhances reliability and capability on or off the road.
