Introducing Holley's latest trussed LS valley covers, a fantastic addition to our extensive selection of LS engine dress-up products! Crafted from high-quality billet aluminum, these valley covers boast a sleek, modern trussed design that adds a subtle yet stylish touch to your LS engine. If you're looking to refresh your engine's appearance, these covers are a perfect choice. The smooth underside is designed to help eliminate Displacement-On-Demand (DOD), providing a generous gasket sealing surface and allowing for the reinstallation of the oil pressure sensor if needed.

Each valley cover is custom machined to fit either the LS1/LS6 (10 bolt) or LS2/LS3/LS7/LSX (11 bolt) patterns. Plus, Holley and Mr. Gasket offer all the gaskets and upgraded hardware you might need to complete your installation seamlessly. You can choose from three stunning finishes: natural billet (with clear anodizing for added protection), polished billet, and black anodized billet.

• If you plan to use the factory top-mounted oil pressure sensor on LS2/LS3/LS7/LSX engines, you’ll need to drill and tap the oil pressure sensor provision carefully. Just use the pre-located pilot hole on the bottom of the valley cover, and make sure to drill and tap it for an M16 x 1.5 male NPT fitting.
• *For DOD Delete applications, be sure to drill and tap all 8 oil port holes to 1/8-NPT and install plugs in the oil ports to prevent any loss of oil pressure.
