Yukon Gear High Performance Thick Gear Set For GM Ci in a 4.11 Ratio

If you're working on a 1963-1979 Chevrolet Corvette and looking to change your final drive ratio, this high-performance ring and pinion gear set from Yukon Gear & Axle is a solid option. This set features a 4.11 ratio, which is a popular choice for improving acceleration, especially if you've added more horsepower or larger tires to your classic Vette. The "thick" designation means it's designed for the specific GM CI (Cast Iron) differential found in these Corvettes, ensuring it fits right.

Yukon engineers put a lot of thought into these gears. They use high-grade steel for both the ring and pinion, and the tooth surface finish is designed to reduce friction and heat. This is important for longevity, especially under high torque conditions or during extended use. They're built to meet OEM specifications, so you can be confident in their fit and function. Yukon also backs these gears 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 crucial to follow the manufacturer's instructions carefully, especially regarding proper gear mesh, backlash, and break-in procedures. This ensures optimal performance and durability. This set is designed for the 8.20-inch ring gear diameter and features a 30-spline pinion.
