Yukon Gear High Performance Gear Set For GM 12 Bolt Car in a 4.11 Ratio

Yukon Gear & Axle has built a solid reputation for making well-built drivetrain parts, and this high-performance ring and pinion set is no exception. If you're looking to change up the gearing in your GM 12-bolt rear end, this set offers a 4.11 ratio that's great for improving acceleration, especially if you've added bigger tires or more horsepower. It's designed to fit a range of classic GM passenger cars, including models like the Chevrolet Chevelle, Pontiac GTO, and Buick Wildcat.

These gears are made from high-grade steel, and Yukon engineers pay close attention to the tooth surface finish. This design helps reduce friction and heat buildup, which is important for both high-torque situations and long-term durability. The fitment is designed to OEM specifications, meaning it should install cleanly into your existing GM 12-bolt differential housing. Yukon also backs these gears with a 1-year warranty against manufacturing defects, and they offer an optional lifetime protection plan.
