Engine Storage Plate GM LS Engines

The Engine Storage Plate GM LS Engines from Moroso is a precision-engineered valley dust cover designed to protect the critical intake valley area of GM LS-series engine blocks during storage, transport, or engine-out maintenance. This product is ideal for serious gearheads rebuilding performance engines, shop technicians managing multiple engine cores, or enthusiasts preparing for an LS swap.

Constructed from heavy-duty steel with a zinc oxide finish, the Engine Storage Plate measures 21.6 inches in length and has a thickness of 0.125 inches (1/8 inch), providing rigid protection without unnecessary weight. The zinc oxide coating resists surface corrosion during extended storage, maintaining structural integrity and appearance through multiple engine builds. At just 4.3 pounds, installation is straightforward, as the plate sits flush in the valley, creating a complete seal against airborne contaminants.

This cover is particularly beneficial for those performing engine assembly or maintenance on LS powerplants, including small-block LS1/LS2 platforms and large-displacement LS7 and LSX variants. It helps keep debris, dust, and contaminants out of the valley cavity where fuel injectors and intake runners converge, preventing potential damage during assembly.
