Yukon Gear High Performance Gear Set For GM 11.5in in a 4.88 Ratio

This Yukon Gear & Axle high-performance ring and pinion gear set includes the ring gear and pinion gear, ready to be installed in your GM 11.5-inch rear axle. This set features a 4.88 gear ratio, which is ideal for vehicles that have been upgraded with larger tires or have had their horsepower increased. A lower numerical ratio like 4.88 helps bring your engine's RPMs back into an optimal range, improving acceleration and drivability after modifications.

Yukon engineers design these gear sets with a focus on reducing friction and heat. They achieve this through a carefully finished gear tooth surface, which is crucial for maintaining performance and longevity, especially under high torque conditions. The gears are made from high-grade steel and are designed to fit OEM specifications, ensuring a solid foundation for your drivetrain. Yukon also backs their products with a 1-year warranty against manufacturing defects, and offers an optional Y.E.S. Plan for lifetime coverage.

This gear set is designed to fit a wide range of GM and Chrysler 11.5-inch rear axles found in popular trucks like the Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and Dodge Ram 2500. Choosing the right gear ratio is key to optimizing your vehicle's performance, especially after significant modifications. Yukon offers a broad selection of ratios to help you dial in your truck's power and efficiency.
