Restore a clean, reliable seal on your GM LS-based V8 engine with this Flashark aluminum valve cover set. Designed as an upgraded replacement for aging factory plastic covers, the set helps address common oil seepage concerns while giving the engine bay a durable, finished appearance.
Important: Verify your Year, Make, Model, engine, and OE number before ordering. Proper sealing depends on clean mating surfaces and even bolt torque during installation.
Confirmed Compatible Applications: Please confirm your vehicle’s year, model, engine and OE part number before ordering. “All Engines” refers only to the applications listed above.

Q: Does this include both valve covers?
A: Yes. This is a complete left and right aluminum valve cover set. Gaskets and bolts are included for installation.
Q: Will this fit every GM LS engine?
A: No. LS-family naming alone does not confirm fitment. Please match your exact Year, Make, Model, V8 engine, and OE number to the vehicle selector before ordering.
Q: Will replacing the valve covers fix my oil leak?
A: It can help if the leak is caused by a cracked, warped, or poorly sealed valve cover. Inspect the gasket surface, PCV-related components, and other possible leak sources before installation.
Q: Do I need sealant during installation?
A: Follow your vehicle service manual. Clean the mating surfaces thoroughly and tighten bolts evenly to specification. Excess sealant or uneven torque can cause sealing problems.
