Yukon 10.5in GM 14 Bolt 4.88 Rear Ring & Pinion Install Kit 30 Spline Positraction

This Yukon Gear & Axle kit gives you everything needed to re-gear the rear differential on a variety of GM trucks and SUVs. You get the 4.88 ratio ring and pinion gear set, a Yukon Master Overhaul Kit with high-quality Timken bearings, and a Yukon Dura Grip clutch-style limited-slip differential. This package is designed for applications with a 10.5-inch ring gear diameter and a 14-bolt rear cover, fitting many Chevrolet and GMC 2500 and 3500 series vehicles from the late 80s through the early 2010s.

Re-gearing your differential can significantly improve performance, especially if you've increased tire size or plan to tow heavier loads. This kit includes a 4.88 ratio, which is a popular choice for larger tires, helping to bring your engine's RPMs back into an optimal range for better acceleration and fuel efficiency. The included Dura Grip limited-slip differential helps improve traction by sending power to both rear wheels, which is especially beneficial off-road or in slippery conditions. Yukon engineers use advanced heat-treating techniques and rigorous testing to ensure their gears meet exacting standards.

This comprehensive package saves you time and money by combining all the necessary components into a single part number. The master install kit contains all the small parts required to complete the differential rebuild, getting your vehicle back on the road quickly. Yukon also backs this kit with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan for the gear set kit.
