The BD-Power 1061825 14-11.5 Differential Cover adds looks, performance, and function to the rear of your 2001-2018 GM/Duramax, or your 2003-2018 Dodge/Cummins. While other differential covers are large and bulky, BD's cast to cool covers are engineered to keep oil on your pinion gear for cooler, longer life, along with built-in cooling fins. The extra capacity sump located on the bottom of the cover almost doubles the fluid capacity! Each differential cover comes complete with stainless steel hardware bolts and a re-useable viton o-ring for a simple, leak free installation.
