Holley Trussed Valley Cover for GM LS1/LS6 - Natural Finish

Introducing Holley's latest addition to our range of LS engine accessories—the Trussed Valley Covers! Crafted from high-quality billet aluminum, these covers boast a sleek, modern trussed design that adds a touch of custom flair to your LS engine. If you’re looking to enhance the look of your engine bay while keeping it functional, these valley covers are a fantastic choice.

The underside of each cover is machined to perfection, which means you can easily eliminate Displacement-On-Demand (DOD) if you choose. Plus, they provide an ample gasket sealing surface and come with provisions for reinstalling the oil pressure sensor if needed.

We offer these valley covers in two different bolt patterns: one for LS1/LS6 (10 bolt) and another for LS2/LS3/LS7/LSX (11 bolt). To make your installation a breeze, Holley and Mr. Gasket provide all the necessary gaskets and upgraded hardware options separately. You can choose from three stunning finishes: natural billet (with clear anodization for added protection), polished billet, and black anodized billet.
