Yukon Gear High Performance Gear Set For GM IFS 7.2in (S10 & S15) in a 3.73 Ratio

If you're looking to change the gearing in your GM IFS 7.2-inch differential, this Yukon Gear & Axle high-performance ring and pinion set is a solid choice. It comes with a 3.73 ratio, which is a popular option for balancing acceleration and highway cruising, especially if you've added more horsepower or larger tires to your vehicle. This set is designed to fit a range of GM trucks and SUVs, including popular models like the Chevrolet S10, GMC Sonoma, and Chevrolet Express vans.

Yukon engineers put a lot of thought into these gear sets. They use high-grade steel for both the ring and pinion gears and employ advanced heat-treating techniques to ensure durability and consistent performance. The tooth surface finish is specifically designed to reduce friction and heat buildup, which is crucial for high-torque conditions and extended use. The fitment is designed to OEM specifications, meaning it should integrate smoothly into your existing 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.

When installing a new ring and pinion set, it's important to follow the manufacturer's break-in procedure carefully to ensure the gears seat properly and achieve their full lifespan. This typically involves a period of moderate driving without hard acceleration or heavy loads. You'll also need to ensure you have the correct installation kit, which usually includes bearings, seals, and shims, as these are not part of the gear set itself.
