Yukon Gear High Performance Gear Set For GM 8.5in & 8.6in in a 4.56 Ratio

If you're looking to get the most out of your GM 8.5-inch or 8.6-inch rear axle, especially after adding more horsepower or upgrading to larger tires, a new ring and pinion gear set is a solid choice. This Yukon Gear & Axle set offers a 4.56 ratio, which is a popular choice for balancing acceleration and highway cruising for many truck and SUV applications. It's designed to fit a wide range of GM vehicles, from classic Caprices and Impalas to modern Cadillac Escalades and Chevrolet Avalanches.

Yukon engineers put a lot of thought into these gear sets. They focus on the tooth surface finish to help cut down on friction and heat, which is crucial for longevity, especially under demanding conditions. They're made from high-grade steel and designed to fit just like the original equipment, making installation more straightforward. This attention to detail means you can confidently add more power to your drivetrain knowing your gears are built to handle it.

When you're diving into a rear axle rebuild or upgrade, remember that a ring and pinion set is just one part of the equation. You'll also need to consider bearings, seals, and potentially a master installation kit to ensure everything goes together correctly and lasts. Yukon Gear & Axle backs these sets with a 1-year warranty and offers an optional Y.E.S. Plan for lifetime coverage.
