The PPE heavy-duty rear Differential Cover is designed as a bolt-on upgrade for your vehicle's stock, stamped steel cover. This cover offers maximum durability thanks to its thick, cast, high-strength nodular iron construction. Our cover has been carefully engineered to optimize your vehicle's approach and departure angles, ensuring that it can navigate any terrain with ease. It is also built to handle the high torsion of challenging off-road environments, with transverse gussets that add strength and rigidity to the housing. The provided hardware is recessed within the cover ensuring that it stays protected from potential damage. This brand-new cover boasts high and low fluid check ports specially designed to cater to the pinion angle changes that come with lifting your Jeep. Each port comes equipped with a billet stainless steel plug that uses a powerful neodymium magnet that effectively removes ferrous metals from the diff fluid, providing ultimate protection for your gears. Additionally, the internal shape of the cover is retained to ensure optimal lubrication. The PPE cast iron Differential Cover is a simple bolt-on installation that replaces your thin stock-stamped steel cover, which is no match for the harsh terrain that your Jeep may encounter. Don't take chances with your differential, upgrade to this innovative cover today and enjoy peace of mind knowing that your Jeep is equipped to handle any challenge.
