DIFFERENTIAL / DRIVETRAIN
Your axle's differential is an important part of your diesel truck, and it pays to install a quality aftermarket differential cover to help protect the differential and provide a performance boost. Our Duramax differential covers do this by providing optimal lubrication for the gears, and by transferring heat from the oil to the outside air. Our differential covers also make it easy to service with fluids. We carry only the highest quality products for our customers.
