If you are looking to dress up your 98.5-02 5.9 Cummins this is the first piece of the puzzle ! Remove the cheap cast valve cover and replace it with this clean looking billet aluminum piece. All parts including the oil fill cap are manufactured in house from solid 6061 T6 billet aluminum. Valve cover includes all stainless hardware and has a spacer system to apply the correct amount of pressure onto the factory gasket.. This cover DOES NOT use the factory bolts ! We include nice stainless socket head bolts to give this cover the cleanest look possible ! Cover comes standard in a machined finish and is available polished, anodized red or anodized blue.
