AMC 20 3.54 ring and pinion gears.

This 3.54 ratio was a factory option in many 1976-1986 Jeep CJ5, CJ7, and CJ8 models (commonly with the 258 inline-6 or certain V8 builds), delivering improved low-end torque and quicker acceleration compared to taller stock ratios like 2.73 or 3.07, while still providing reasonable highway RPMs and fuel efficiency for daily driving or light off-road use with stock to 33" tires. It uses the 3.07-up carrier (per AMC 20 carrier breaks) and is a popular mild upgrade or restoration choice for better responsiveness without sacrificing too much top-end speed—ideal for mixed street/trail driving or when adding modest tire size. Browse a wide variety of AMC 20 ring and pinion gears in 3.54 ratio from trusted brands including Yukon Gear, Motive Gear, Crown Automotive, and others to pair with installation kits, precision bearings, heavy-duty shafts, and traction devices for a complete, reliable regear that boosts drivability and capability.
