Premium Upgraded Gears for Performance Applications

When you need a more aggressive launch, improved acceleration, or simply need to compensate for larger tire and wheel combinations, jumping to a set of 5.38 Ratio gears will take you further so you can explore more. Using innovative technology, design and construction, the engineers at Yukon have successfully created a quiet running gear that will help improve the overall performance of your truck's drivetrain. The altered power band provided by these gears can also improve the overall towing and hauling performance of your ride by giving your Sierra/Silverado a more aggressive operating speed for some extra power through your truck's shifting. The 5.38 ratio is a perfect choice for those who need a more efficient range when you throw on larger tires and wheel, giving your truck nice acceleration and plenty of pull from a dead stop.

High-Quality Gear Steel and Installation Info

Yukon Gear & Axle manufactured their 11.5" Ring & Pinion Gear using only premium materials and the latest design processes to ensure maximum performance and long-lasting functionality without compromise. Yukon builds each one of these gear sets out of a forged triple-alloy 8620 steel that is tough enough to handle just about anything you throw its way. The gear teeth are cut by Yukon's highly skilled, expert machinists before going through a computer-controlled lapping process that gives the gears an ultra-fine finish for quiet operation. Both the ring and pinion are designed as direct bolt-on replacements for stock components and work flawlessly with Yukon's Master Install Kit.
