Finally happy with my new diff. cover design. It builds on 12 years of experience designing and manufacturing these for other companies. We're going to start with the Dana M210 and M220 Axles that are under a variety of Jeeps, including the JL and JT models. Key features include a 3/8" fully bump formed main ring gear protection plate with integrated magnetic drain plug. The bump formed full round shape ensures proper oil flow to all the necessary components of the axle, just as Dana intended. It also happens to be one of the strongest shapes that exists, based on geometry. The mounting ring is laser cut from 3/8" plate as well. All of our diff covers have the holes drilled and counter bored after welding and the sealing surface is decked for flatness on our CNC mill. The fill plug is magnetic as well, sealed with a double O-ring seal. The bung for that is thick enough to prevent any damage from rocks on the head of the plug. Stainless steel hardware will come standard with all of our covers and as always, they will be welded fully inside and out.
