Yukon Gear High Performance Gear Set For Dana S130 in a 4.30 Ratio

If you're looking to optimize your vehicle's performance, especially after adding significant horsepower or upgrading to larger tires, a new ring and pinion gear set is a critical component. This high-performance set from Yukon Gear & Axle is specifically designed for Dana S130 differentials, featuring a 4.30 ratio. This ratio is often chosen to bring your speedometer back into calibration after tire size changes or to improve acceleration and towing capability by allowing the engine to operate at a more effective RPM range.

Yukon engineers put a lot of thought into these gear sets. They use high-grade steel for both the ring and pinion, ensuring a strong foundation. The gear tooth surface finish is carefully designed to reduce friction and heat buildup during operation, which is crucial for longevity and consistent performance, especially under demanding conditions. The fitment is designed to OEM specifications, meaning it should integrate properly with your existing Dana S130 differential housing. This set includes a 12.25-inch ring gear diameter and a 34-spline pinion, ensuring it's ready for robust applications.

Beyond the robust construction and performance-oriented design, Yukon Gear & Axle backs this gear set with their Y.E.S. Plan. This is a lifetime, no-questions-asked protection plan that covers your gear set for as long as you own your vehicle, offering significant peace of mind for such a substantial drivetrain upgrade. When installing a new ring and pinion, it's important to follow the manufacturer's break-in procedure carefully to ensure the gears mesh properly and achieve their full lifespan.
