A differential cover is needed to protect a differential from damage and keep lubricant inside. A factory differential cover is enough for city roads but can be insufficient during off-road journeys because of heavy loads and hard conditions. In this case, you may need an aftermarket differential cover. It provides better protection and extra cooling and keeps an additional portion of oil inside the assembly. Performance covers are worth considering if your Dodge Ram has been subjected to an extensive upgrade. After you lift the body several inches up and install mud terrain tires to make the truck suitable for demanding trails, the next step will be protecting the diff from anything these trails can throw your way.

If off-roading is your thing, you have come to the right place. Our store offers Dodge Ram performance differential covers and other solid performance parts you may need to prepare your truck for off-road adventures. These aftermarket products are thoughtfully designed and made from premium-quality materials to match the strictest technical requirements. Many aftermarket differential covers contain a magnetic drain plug attracting small steel particles and keeping a lubricating fluid cleaner this way (it is recommended just to clean the magnet itself periodically).
