LS Timing Cover Gasket 1997-Up

The LS Timing Cover Gasket 1997-Up from Straub Technologies Inc. is a precision engine seal designed for GM LS-series engines. This gasket serves as the critical seal between the timing cover and cylinder head, preventing oil leakage that would compromise engine performance and reliability. The 0.06-inch thickness strikes the correct balance between sealing integrity and proper gasket compression under engine clamp loads.

Constructed from aluminum and rubber composite material, this gasket handles the thermal cycling and pressure variations inherent to LS engine operation. The aluminum core provides structural rigidity and dimensional stability across the temperature range from cold start to sustained high-load running, while the rubber compound creates a deformable surface that conforms to the mating surfaces of the timing cover and block. This hybrid construction is standard across OEM and quality aftermarket LS gaskets because it effectively seals without over-compressing and blocking oil passages.

This gasket is essential for engine builders, mechanics, and LS enthusiasts performing timing cover removal, water pump service, or complete engine assembly on 1997 and later LS-platform vehicles. Whether supporting a stock rebuild, performance upgrade, or swap application, a quality timing cover gasket is non-negotiable—leaking oil at the front of the engine accelerates corrosion, fouls accessory belts, and signals unaddressed seal failure. The Straub Technologies part number 346-3904 is the direct replacement for OEM and performance rebuild specifications.
