Yukon Gear High Performance Gear Set For GM 8.5in & 8.6in in a 3.73 Ratio

This Yukon Gear & Axle high-performance ring and pinion gear set includes the ring gear, pinion gear, and necessary hardware for installation. It's designed to fit GM 8.5-inch and 8.6-inch differentials, offering a 3.73 gear ratio. This setup is a solid choice for vehicles like the Chevrolet C1500, Cadillac Escalade, or Buick Rainier when you're looking to optimize your drivetrain for better performance, whether you've added more horsepower, larger tires, or simply want to improve your vehicle's responsiveness.

Yukon engineers put these gear sets through rigorous design and testing processes, ensuring they meet exacting standards. They use high-grade steel for both the ring and pinion, and the gear tooth surface finish is treated to reduce friction and heat. This means the gears can handle high torque conditions and extended use, making them well-suited for demanding applications. The 3.73 ratio is a popular choice for balancing acceleration and highway cruising, providing a noticeable improvement over stock gearing in many trucks and SUVs.

When installing this gear set, it's important to follow the manufacturer's recommended break-in procedure to ensure proper seating and longevity. Yukon Gear & Axle also backs these sets with a 1-year warranty against manufacturing defects, and they offer an optional Y.E.S. Plan for lifetime coverage.
