What is the purpose of changing the gear ratio?

Changing your gear ratio, like with this 3.54 set, affects how your vehicle's engine speed relates to its wheel speed. A lower numerical ratio (like 3.54 compared to a stock 4.10) generally improves highway fuel economy and reduces engine RPM at cruising speeds, while a higher numerical ratio improves acceleration and towing power.

What is the Y.E.S. Plan?

The Y.E.S. (Yukon Extended Service) Plan is an optional lifetime protection plan offered by Yukon Gear & Axle. It provides comprehensive, no-questions-asked coverage for your gear set for as long as you own the vehicle, offering peace of mind beyond the standard warranty.

What is the recommended break-in procedure for new gears?

After installation, it's essential to follow a specific break-in procedure to properly seat the new gears. This typically involves a period of moderate driving, avoiding hard acceleration or heavy loads, and often includes a series of heat cycles. Always consult the manufacturer's instructions for the exact recommended procedure.

Product Details

If you're looking to change up the gearing in your AMC Model 20 differential, perhaps to better suit larger tires or a more powerful engine, this Yukon Gear & Axle high-performance ring and pinion set is a solid choice. This set features a 3.54 ratio, which is a popular option for balancing highway drivability with off-road or towing needs. It's designed to fit the AMC Model 20 axle, a common rear end found in a variety of classic American Motors vehicles, Jeeps, and even some Hummer H1 models from the early 2000s.

Yukon engineers put a lot of thought into these gear 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, especially under demanding conditions like high torque situations or extended runs. The fitment is designed to OEM specifications, so you can expect it to install correctly into your differential housing. Yukon also backs these sets with a 1-year warranty against manufacturing defects, and they offer an optional lifetime Y.E.S. Plan for comprehensive protection as long as you own your vehicle.

When installing a new ring and pinion set, it's crucial to follow the manufacturer's break-in procedure to ensure proper seating and longevity. This typically involves a period of moderate driving with specific temperature and mileage guidelines. Always refer to the installation instructions provided by Yukon Gear & Axle for the correct procedure, as well as any specific tools or setup equipment you might need for a successful installation.
