Valley Cover - Trussed GM LS2/LS3/LS7/LSX

The Valley Cover - Trussed GM LS2/LS3/LS7/LSX from HOLLEY is designed for serious LS engine builders and performance enthusiasts who require reliability and clean aesthetics under the hood. This precision-machined valley cover acts as a barrier between the valve covers and intake manifold, protecting internal engine components from contamination while ensuring proper oil circulation.

The trussed design of the valley cover provides superior structural rigidity compared to flat covers, preventing flex and potential gasket failure under high boost pressures or aggressive cam profiles typical in modified LS platforms. HOLLEY's engineering guarantees a proper fitment across the LS2, LS3, LS7, and LSX engine families, with integrated gasket sealing surfaces that help eliminate oil leaks—a common issue in heavily modified engines.

This valley cover is ideal for engine rebuilds, turbo conversions, and any LS swap requiring OEM-quality component replacement or upgrade. Both professional mechanics and weekend enthusiasts will appreciate the bolt-on simplicity of installation, making it a valuable addition to any performance engine build.
