Our wheel seals are engineered using only the highest-quality materials to meet vehicle manufacturer specificatons. We work with suppliers to design seals that meet FAG’s quality standards. Seals are designed to protect wheel end components from contamination – such as dirt, dust, and moisture – and prevent the loss of grease over the life of the bearing. The specifications for wheel seals are very demanding, and the type required depends on the specific application, position and vehicle class.

If you venture off the beaten path, plow snow, or subject your truck or SUV to extreme conditions, this rugged rear differential cover will boost the protection and personality of your vehicle’s drivetrain. Instead of the vulnerable thin stamped steel original equipment cover, this diff cover is precision-engineered from thick ductile iron and boasts an attractive, corrosion-resistant wrinkle coating. Rocks, trail hazards and damaging debris can easily ding an ordinary differential cover, leading to oil leaks and cracks. Plow trucks undergo stress due to the weight of salters and plows, and the no-brakes impacts of hidden potholes, coupled with the corrosive nature of all the salt season after season. This cover also features two filler plugs, which can help ease the difficulties of filling through the factory plug located on the axle housing. The cover is also fitted with a drain plug to make fluid exchanges quick, easy, and remove the need for replacing the differential cover gasket. This extra-rigid replacement will help keep critical components safe while adding a serious cool factor, especially on lifted vehicles. Want to customize your diff even more? We’ve made the stainless steel Dorman logo plate removable so you can replace it with the plate and logo of your choice. The cover comes complete with all necessary bolts and plugs for a complete upgrade.

Product Features:

• Enhanced protection – ideal solution for off-road or snowplow vehicles that need additional protection from damaging rocks and other hazards that can crack an ordinary stamped steel differential cover
• Precise fit – engineered to exacting specifications to match the fit and function of the original equipment differential cover for a seamless installation on specified Ford and Lincoln vehicles
• Upgraded repair – made from rigid ductile (also known as nodular) iron with an attractive, corrosion-resistant wrinkled finish, and includes required bolts and three plugs for a complete installation and simplified maintenance
• Customize it – includes a stainless steel Dorman logo plate that’s removable so you can replace it with the plate and logo of your choice
