The Yukon Gear adaptor washer permits a 28-spline pinion to seat properly in an oversized 35-spline pinion support for Ford 9-inch differentials. Intended for Ford 9" applications, the washer provides the required spacing and fitment when mating smaller pinions to larger supports during rebuilds or conversions, offering a simple way to maintain correct alignment and support without altering the pinion itself.
