Yukon Gear & Axle YA F880072 Rear Axle Shaft Ford 8.8in. Differential 34 Spline 35.8in. LH 6-Lug

The Yukon Gear & Axle YA F880072 is a left-hand rear axle shaft designed as a direct replacement for the Ford 8.8-inch differential. Featuring a 34-spline design, a total length of 35.8 inches, and a 6-lug bolt pattern, this axle shaft delivers an immediate strength upgrade over the factory unit without requiring any modifications.

Manufactured from high-quality 1541H alloy steel, this axle benefits from advanced heat-treating technology that penetrates deeper than standard factory processes, resulting in a shaft that is significantly stronger than OEM in the bearing and seal area. Yukon's rolled spline production method further increases spline strength compared to conventional cut splines, making this axle well-suited for demanding street, off-road, and track applications.
