The FOX top-out shaft assembly lists a 2.750-inch body diameter with a 0.875-inch shaft and includes a top-out bumper made of Viton. Intended as a damper internal component, it offers a specific bore-to-shaft profile to restore end-of-travel cushioning. Keep this part on hand for rebuilding or replacing worn internal bumping components with a matched Viton bumper.
