AMC 20 3.08 Ring and Pinion Gears

This 3.08 ratio was a common factory option in various 1976-1986 Jeep CJ5, CJ7, CJ8, and some full-size Jeep models (often paired with the 258 inline-6 or V8s), offering a moderate improvement in low-end torque and acceleration compared to the taller 2.73 gears while maintaining low highway RPMs and good fuel efficiency for daily driving or light off-road use with stock to ~31" tires. It generally fits the 3.07-up carrier design (per AMC 20 carrier breaks, with some specific 3.08 compatibility notes), making it a solid choice for mild upgrades, restoration projects, or prioritizing comfortable highway cruising and passing power without aggressive low-end focus—ideal for mixed street use where revs stay reasonable (around 2500 RPM at 75 mph with 31" tires in overdrive setups). Browse a wide variety of AMC 20 ring and pinion gears in 3.08 ratio from trusted brands including Motive Gear, Yukon Gear, Revolution Gear, Crown Automotive, and others to pair with installation kits, precision bearings, heavy-duty shafts, and traction devices for a smooth, reliable regear that enhances drivability without excessive engine strain.
