Product Description

The Yukon YY GM40015850 is a heavy-duty pinion yoke designed for GM 7.5" and 7.625" rear ends using 27-spline shafts and mechanical 3-R U-joints. Precision-machined with a 1.125" bearing cap diameter and a 2.556" snap-ring groove, it provides an exact OEM-style fit.

What sets this yoke apart is its triple-lip seal system, which protects the pinion seal area from dirt, moisture, and oil--ideal for high-stress, off-road, or high-mileage applications. Finished in black phosphate for corrosion resistance, it's factory-quality and backed by Yukon's 1-year workmanship warranty.
