This Yukon Gear & Axle thin gear set features a 3.73 ratio, designed for GM 12-bolt passenger car differentials. The gear tooth surface finish is engineered to reduce friction and heat, which is crucial for high torque conditions and extended use. Yukon uses high-grade steel for both the ring and pinion, ensuring durability and performance that meets OEM specifications. This set is specifically designed for use with 4.10 and up differential carriers, making it a suitable choice for those looking to optimize their vehicle's performance, whether you've added significant horsepower or upgraded to larger tires.

The 8.875-inch ring gear diameter and 30-spline pinion are key specifications that ensure proper fitment within the GM 12-bolt housing. Yukon's commitment to quality is backed by rigorous testing processes, ensuring each gear set meets exacting standards. This 3.73 ratio offers a noticeable improvement in acceleration and towing capability compared to stock gearing, without excessively sacrificing highway cruising efficiency. It's a popular choice for muscle cars and trucks from the 1960s and 70s, such as the Chevrolet Chevelle, Pontiac GTO, and Buick Wildcat, when rebuilding or upgrading the rear end.

When you choose Yukon Gear & Axle, you're investing in a product built for demanding conditions. They offer a comprehensive Y.E.S. Plan, a lifetime protection plan that covers your gear set for as long as you own your vehicle, providing peace of mind for this significant drivetrain upgrade.
