Katech GM Gen III & IV Cast Aluminum Wet Sump Valve Covers | Non-Slotted with Oil Fill

CAST ALUMINUM CONSTRUCTION · INCREASED VALVETRAIN CLEARANCE · CLEAN NON-SLOTTED DESIGN

The Katech GM Gen III & IV Cast Aluminum Wet Sump Valve Covers are engineered for compatible GM Gen III and Gen IV LS wet sump engines. Their raised cast aluminum design provides additional clearance for many aftermarket valve springs, rocker arms, and other high-performance valvetrain components while delivering a clean, purpose-built appearance.

Designed with serviceability in mind, the valve covers allow the complete assembly to be removed without first removing the ignition coils. An optional Katech Ignition Coil Relocation Kit is available to reposition the coils above the valve covers, keeping the covers fully visible and creating a cleaner engine compartment.
