Alloy USA Ring & Pinion Sets for 76-86 Jeep CJ with AMC Model 20 Rear Axle

These affordable high strength gear sets come in all the popular ratios to satisfy everyone's gearing needs. Oversized tires require higher ring & pinion ratios to restore performance. Made from high quality 8620 forgings and Gleason gear cutting technology, these gears are made to last. Complete installation kits are available separately to complete the job. Exclusive 5-year warranty. Available in 3.73, 4.10, 4.56, 4.88 and 5.13 ratios. When replacing 2.73 with a 3.31 or numerically higher gear set, the case must be changed to a 3.31 and higher case.
