JE Pro Seal GM LSX 4.055in 0.059in Headgasket - Left

JE Pistons is a well-known name in the performance engine world, often chosen for their high-quality internal components. This specific head gasket, the GM1029-059, is designed for GM LSX engines and measures 4.055 inches in bore diameter and 0.059 inches in thickness. It's intended for the left side of the engine.

This gasket is built with a multi-layer steel (MLS) construction, which is a popular choice for performance builds because it offers excellent sealing capabilities under high pressure and temperature conditions. The MLS design helps prevent leaks and ensures a solid seal between the cylinder head and the engine block, crucial for maintaining compression and preventing coolant or oil from entering the combustion chamber. Its specific bore size and thickness are important considerations when rebuilding or modifying your LSX engine to ensure proper compression ratios and cylinder head sealing.
