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 3.21 Ratio gears will take you further so you can explore more. Using innovative technology and design, the engineers at Yukon have successfully created a quiet running gear that will help improve the overall performance of your truck's drivetrain without compromise. The altered power band provided by this gear set can also improve the towing and hauling performance of your ride by giving your Sierra/Silverado a more aggressive operating speed for some additional power through your truck's shifting. The 3.21 ratio is a perfect choice for anybody that values outright performance over improved fuel economy, giving you an extra boost of confidence each time you set off for adventure.

High-Quality Gear Steel & Installation Info

Yukon Gear & Axle developed their 10.5" 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 kits from a forged triple-alloy 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. The ring and pinion gear is designed as a direct bolt-on replacement over stock, and works flawlessly with Yukon's Master Overhaul Kit!
