Yukon High Performance Yukon Replacement Ring & Pinion Gear Set for Dana S130 In A 4.88 Ratio

If you're looking to optimize your vehicle's performance, especially after adding larger tires or more horsepower, a Yukon Gear & Axle ring and pinion set is a solid choice. This specific set is designed for the Dana S130 axle and features a 4.88 gear ratio. This ratio is often chosen to bring your speedometer back into calibration after tire upgrades or to improve acceleration and towing capability by allowing the engine to operate at a more efficient RPM on the highway.

Yukon engineers put a lot of thought into these gear sets. They use high-grade steel for both the ring and pinion gears, and the tooth surface finish is designed to reduce friction and heat buildup during operation. This attention to detail helps ensure a smooth, quiet operation and a long service life. The ring gear diameter is 12.25 inches, and it uses 10 ring gear bolts, with the pinion featuring 34 splines, all designed to meet OEM specifications for a proper fit.

Beyond the robust construction, Yukon Gear & Axle backs this ring and pinion set with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan. This offers significant peace of mind for such a critical drivetrain component. While this set is designed to fit the Dana S130 axle, it's always a good idea to confirm fitment for your specific vehicle application, as gear changes are a significant modification that requires careful installation by a qualified professional.
