The Yukon Gear & Axle 10.5-inch Ford 4.30 rear ring-and-pinion install kit pairs a 10.5" ring and pinion with a Yukon Master Install kit so you can rebuild a 12-bolt rear end with one part number. It contains bearings, seals and the small parts needed to finish a re-gear, including Timken-quality components. Yukon’s manufacturing and heat-treating processes are tested to exacting standards and the kit carries the Y.E.S. lifetime coverage.
