Description
Looking to give your 5.9 Cummins engine bay a serious upgrade? We’ve got you covered.
Ditch the flimsy factory plastic valve cover and CCV filter assembly and replace it with a precision-machined billet aluminum valve cover that looks as good as it performs. Available in Anodized Red, Anodized Black, American Flag, Polished, or Raw, you can choose a finish that perfectly matches your truck’s personality.
But this cover is far more than a cosmetic upgrade—it’s a performance piece engineered for real results.
Performance-Driven Design
Our billet valve cover eliminates the restrictive, maintenance-heavy factory CCV filter and replaces it with a maintenance-free baffled CCV vent system. No more spending money on expensive replacement filters.
This upgraded ventilation setup keeps crankcase pressures stable at higher RPM, ensuring your Cummins runs cleaner, smoother, and at peak performance under load.
Premium Components Included
Every valve cover comes complete with:
-
Billet aluminum oil fill cap (other styles available)
-
Baffled billet CCV canister with a -12 ORB to 1″ hose barb
-
Stainless steel socket head hardware
-
O-ring sealing surfaces for a clean, leak-free installation
-
Rubber plug for the drain adapter plate
-
All components—including the oil fill cap—are proudly manufactured in the USA from solid 6061-T6 billet aluminum for uncompromising strength and durability.
Built for Easy Installation
This valve cover is designed for straightforward, garage-friendly installation. If you’ve got the tools, basic know-how, and a good attitude, getting this cover installed is smooth and simple.
Style. Strength. Performance.
This is the 5.9 Cummins valve cover that transforms your engine bay while delivering real benefits where it counts.
