Yukon Gear High Performance Gear Set For GM 12P in a 3.31 Ratio

Yukon Gear & Axle has built a solid reputation for making dependable drivetrain components, and their high-performance ring and pinion gear sets are a prime example. If you're looking to change your vehicle's gear ratio for better performance with added horsepower or larger tires, this set is designed for the GM 12-bolt rear axle. It features a 3.31 ratio, which is a popular choice for balancing acceleration and highway cruising, especially when you've upgraded your vehicle's setup.

These gears are made from high-grade steel and are designed to meet OEM specifications for a direct fit. Yukon engineers pay close attention to the tooth surface finish, which helps to reduce friction and heat. This is important for long-term durability, especially under high torque conditions or during extended use. The set includes 30-spline pinion and uses 12 bolts to secure the ring gear, fitting axles with an 8.875-inch ring gear diameter. This particular gear set fits a wide range of classic GM vehicles, including models like the Chevrolet Chevelle, Pontiac GTO, and Buick Wildcat from the mid-60s to early-70s.

When you choose Yukon, you're not just getting a gear set; you're investing in peace of mind. Each set comes with a 1-year warranty against manufacturing defects. Plus, Yukon offers their Y.E.S. Plan, a comprehensive lifetime protection plan that covers your gears for as long as you own the vehicle. This level of support underscores their confidence in the quality and longevity of their products.
