Add a stylish look to your front and rear end with a BD Front Diff cover. Made from cast aluminum, BD differential covers have both internal and external fins for extra cooling plus a sleek curved design. Rear cover design deflects the oil back onto the ring gear and into the pinion gear for cooler longer life. Comes with separate fill and drain ports with stainless steel plugs for easier servicing. Includes stainless steel Allen head cap bolts and magnetic drain plug to help capture suspended material in the oil. Designed to be compatible with aftermarket track bars.
