Tab will move on to the next part of the site rather than go through menu items.

If you are looking to dress up your Dodge Cummins this is the first piece of the puzzle! Remove the cheap plastic valve cover / CCV filter and replace it with this sweet billet aluminum piece. Our valve covers not only look great, but have been designed to work properly. Our billet covers are designed to maintain the correct amount of pressure on the factory gasket for a leak free seal! Rather then sell a cover that uses your factory plastic fill cap, we precision machine an oil fill cap to perfectly match the threads on our valve covers.
