LS valley covers

$200.00

Hardcore Precision Machining LS billet valley covers are CNC-machined from high-quality aluminum for strength, durability, and a clean professional appearance. Designed for GM LS-based engines, our valley covers provide a precise fit and improved sealing over factory stamped covers, making them ideal for high-performance, street, and race applications.

Each cover is engineered with tight tolerances to ensure proper oil control and crankcase ventilation compatibility. Our billet construction resists warping under heat and pressure, while offering a sleek, custom look that complements any LS engine build.

Whether you’re upgrading a stock engine or completing a full performance build, Hardcore Precision Machining delivers American-made quality you can trust.
