The WINTERS Drive Retaining Washer (MPN 5037) is a steel retention washer built to secure the drive yoke bolt in Winters quick change rear ends. This is a purpose-specific racing hardware component, not a generic flat washer — it holds the yoke bolt assembly in place under the vibration and shock loads that a quick change center section sees on dirt and pavement. With a 1-1/2 inch outside diameter and a 3/8 inch bore, it drops directly into the drive yoke position where a standard washer won't fit the application. Racers running quick change gear sets keep these on hand as a replacement wear item.
The 5037 measures 1-1/2 inch OD, 3/8 inch ID, and 1/8 inch thick, machined from steel and finished in black oxide for corrosion resistance and a clean look inside the housing. The 3/8 inch bore matches the drive yoke bolt shank, and the thickness gives the bolt head a proper bearing surface against the yoke so clamp load stays consistent through repeated heat cycles. Black oxide adds a mild rust barrier without building up dimension, so the washer seats flat every time. It pairs with the drive yoke assembly components in a quick change build, and shooters shopping our broader washer selection or the full fasteners category will find related retention hardware for the same drivetrain jobs.
Buy this washer when you're rebuilding a quick change center section, servicing the drive yoke bolt, or restocking your spares box before a race weekend. Because it lives in a high-load, high-vibration spot, inspecting and replacing the retaining washer during any yoke or bolt service is smart practice. It ships light and stores easily, so keeping a few in the trailer costs almost nothing.
