Upgrade a worn or damaged factory cover with this EVIL ENERGY LS valve cover set for select GM 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L V8 applications. The kit includes both left and right aluminum covers, matching gaskets, and mounting bolts, giving you the main components needed to service both cylinder heads together.
For drivers, restorers, and LS-based project builders comparing aftermarket valve covers, this set combines vehicle-specific compatibility with a rigid aluminum construction and a clean silver finish.

LS-family engines were used across many vehicles and model years, so engine displacement alone should not be used to confirm fitment. Before ordering these LS valve covers, compare the original left and right cover design, mounting points, engine configuration, and OE reference numbers with the specifications above.
Compatible applications may include select Chevrolet Silverado, Tahoe, Suburban, Avalanche, Corvette, Camaro, and Express models, along with related GMC, Cadillac, Pontiac, Hummer, Isuzu, and Saab platforms. Always confirm the exact engine and original cover configuration before purchase.
If you are searching for a Chevy valve cover for an LS-based truck, SUV, performance vehicle, or project engine, focus on compatibility rather than vehicle name alone. Different Chevrolet models and LS-series engines can use different cover configurations, making OE number and original-part comparison important before installation.
The same principle applies when comparing Chevrolet valve covers across different generations: a similar engine displacement does not automatically mean the valve covers are interchangeable.
Replacement may be appropriate when the original covers are cracked, warped, physically damaged, or no longer providing a reliable sealing surface for the gaskets. Oil around the valve cover perimeter can indicate a sealing issue, but the source should be inspected before parts are replaced.
Because this product is supplied as a two-piece valve cover set, it is especially useful when you want to service both sides at the same time rather than replacing only one aging cover.

Before installation, remove old gasket material, oil, and debris from the cylinder head mating surfaces. Check that each gasket is seated correctly before positioning the covers.
Because aluminum valve covers are rigid, tighten the mounting bolts evenly and follow the torque specification and tightening sequence recommended for your engine. Excessive torque, uneven tightening, or an incorrectly seated gasket can affect sealing performance.
