The last thing you want to see on your rebuilt, powder coated transfer case is rust. Here at transfer case solutions, we go the extra mile to not only get rid of rust on all parts, but inhibit and prevent rust from coming back. We use the strongest, most durable, longest lasting, rust inhibitor oil on the market. We coat all the internals of the transfer case, as well as, input and output shafts. The oil prevents rust from forming by creating a barrier on the surface at molecular level. It also double as a lubricant. Allowing parts to be installed seamlessly. Transfer case solutions doesn't stop there in preventing rust. All transfer cases are then put in to a special Poly VCI bag and heat sealed, to add an extra layer of rust prevention. We take pride in how your transfer case performs and looks.
