GM Truck Billet Valve Covers - L8X (Pair)

TooHighPsi Performance L8X Valve Covers are specifically designed for use on GM truck Gen5 L8X V8 direct injected engines. They work seamlessly with any of our THP Port Plates allowing adequate clearance for injectors and fuel rails, plus relocating coils for fitment with the Magnuson 2650 or any other brand/model of supercharger or intake manifold. They look great and will make your engine build look stunning under the hood!

The THP 2-piece billet Valve Covers feature full baffling for OEM level oil control, a -16 ORB machined oil fill port for your choice of cap, and a -10 ORB machined port for your choice of breather fitting. The THP Valve Covers are available with and without coil mounts, and in raw aluminum billet finish or anodized in black, bronze, blue, or red.

Our THP LTX Valve Covers require the use of the reusable press-in-place gasket from the factory valve covers. Due to differences in the design of coil packs, the GM Truck/SUV option comes with black anodized spacers and hardware to allow correct fitment. 

Covers are sold in pairs and are proudly made in the USA!
