Yukon Gear High Performance Gear Set For GM 8.2in (Buick / Oldsmobile / and Pontiac) in 3.90

Starting with a 3.90 gear ratio, this Yukon Gear & Axle ring and pinion set is built for performance applications. It’s designed for GM 8.2-inch rear ends found in many Buick, Oldsmobile, and Pontiac vehicles from the mid-60s to early-70s. This ratio change can significantly improve your vehicle's acceleration by allowing the engine to reach higher RPMs more quickly, which is especially noticeable when you’ve added horsepower or larger tires.

Yukon engineers use high-grade steel for both the ring and pinion gears, and they pay close attention to the tooth surface finish. This design helps reduce friction and heat buildup, making the gears more durable under high torque conditions and during extended use. The fitment is designed to OEM specifications, meaning it should install correctly into your existing differential housing, provided it's the correct 8.2-inch BOP style.

This set is a solid option if you're looking to re-gear your classic GM vehicle for improved performance. Yukon also offers a lifetime Y.E.S. Plan for comprehensive protection on your investment.
