Yukon Gear High Performance Gear Set For GM 11.5in in a 4.56 Ratio

This Yukon Gear & Axle ring and pinion gear set includes the ring gear and pinion gear, ready for installation in your GM or Chrysler 11.5-inch rear axle. It features a 4.56 gear ratio, which is a popular choice for those looking to optimize performance after adding significant horsepower or upgrading to larger tires. This ratio helps bring your engine's RPMs back into a more efficient range for highway cruising or towing, improving drivability and fuel economy compared to stock gearing in modified vehicles.

Yukon engineers use advanced heat-treating techniques and design processes to ensure these gears meet exacting specifications. The gear tooth surface finish is specifically designed to reduce friction and heat buildup, which is crucial for long-term durability under high torque conditions. They are made from high-grade steel and designed to fit OEM specifications, meaning they integrate smoothly into your existing differential housing. This attention to detail in manufacturing and material selection makes them a solid option for demanding applications.

Beyond the gears themselves, Yukon offers a Y.E.S. Plan, a lifetime protection plan that covers your gear set for as long as you own the vehicle, providing extra peace of mind. This set is designed for a wide range of heavy-duty trucks, including models like the Chevrolet Silverado 2500 HD and Dodge Ram 2500. Remember that installing a new ring and pinion set typically requires specialized tools and knowledge, and it's often recommended to replace other differential components like bearings and seals at the same time.
