Yukon Gear High Performance Gear Set For Model 20 in a 4.56 Ratio

If you're looking to re-gear your differential to better handle larger tires or a significant horsepower increase, this Yukon Gear & Axle ring and pinion set is a solid choice. It's designed for the AMC Model 20 differential, offering a 4.56 ratio that's popular for balancing acceleration with highway cruising, especially after modifications.

Yukon engineers put a lot of thought into these sets. They use high-grade steel for both the ring and pinion gears, and the tooth surface finish is specifically designed to cut down on friction and heat. This means your gears will run cooler and last longer, whether you're on a long race or just dealing with high torque conditions. The fitment is designed to OEM specifications, so you can expect it to install correctly in your Model 20 differential. This set is built to be a durable upgrade for a wide range of vehicles, including many AMC models like the Javelin and Pacer, as well as Jeep CJ models.

When you're re-gearing, it's important to have confidence in your parts. Yukon offers a 1-year warranty against manufacturing defects, and they also have a lifetime Y.E.S. Plan for added peace of mind. Make sure to follow the manufacturer's installation instructions carefully, as proper break-in procedures are crucial for new gear sets.
