FAQ
Will this fit 2006–2007 5.9L or 6.7L trucks?No—this model is designed for 2003–2005 5.9L CR layouts. See our valve covers category for late-model options.
Do I need a catch can with this cover?It’s optional but recommended on higher-power builds to control oil vapor. The -12 ORB ports make plumbing simple.
Is a gasket included?No. Order an OEM or MAHLE gasket separately for best sealing (see Recommended Parts above).
Is the finish polished?No. This item ships in a machined billet finish from the manufacturer.
