Yukon Gear High Performance Gear Set For Model 20 in a 4.88 Ratio

If you're looking to change your vehicle's gearing for better performance, especially after adding larger tires or more horsepower, this Yukon Gear & Axle high-performance ring and pinion set is a solid choice. It's designed for the AMC Model 20 differential and comes in a 4.88 ratio, which is a popular choice for increasing torque and improving acceleration. This set is built to handle demanding conditions, making it suitable for a wide range of vehicles like the Jeep CJ series, AMC Pacer, and even the Hummer H1.

Yukon engineers put a lot of thought into these gears. They use high-grade steel for both the ring and pinion, ensuring they can stand up to high torque applications. The tooth surface finish is specifically designed to reduce friction and heat buildup, which is crucial for long races or sustained high-torque situations. This attention to detail means you get a well-built gear set that fits to OEM specifications, so you can be confident in its performance and longevity. Yukon also backs these gears with a 1-year warranty against manufacturing defects, and they offer an optional Y.E.S. Plan for lifetime coverage, giving you extra peace of mind.

When installing a new gear set like this, it's important to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving without hard acceleration or heavy loads, followed by an oil change. This process helps to properly seat the new gear teeth and ensures optimal performance and durability for years to come.
