Holley Valley Cover - Trussed Design for GM LS2/LS3/LS7/LSX (Black Anodized)

Introducing Holley's latest trussed LS valley covers, a fantastic addition to our extensive range of LS engine dress-up products! Crafted from high-quality billet aluminum, these valley covers boast a sleek, modern trussed design that adds a touch of custom flair to your LS engine.

The smooth underside of these covers not only looks great but also helps eliminate Displacement-On-Demand (DOD) functionality. Plus, they provide a generous gasket sealing surface and come with provisions for reinstalling the oil pressure sensor if you need it.

Each valley cover is precision machined to fit either the LS1/LS6 (10 bolt) or LS2/LS3/LS7/LSX (11 bolt) bolt patterns. To make your installation seamless, Holley and Mr. Gasket offer all the essential gaskets and upgraded hardware options separately. You can choose from three stunning finishes: natural billet (clear anodized for protection), polished billet, or sleek black anodized billet.

Notes:

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