GM LS Titan Copper LH Gasket 4.160 X .050

The SCE Gaskets GM LS Titan Copper Left-Hand Gasket (4.160 x .050) is a precision-engineered cylinder head gasket engineered for GM LS-series engine builds. This driver-side gasket features a 4.160-inch bore diameter and 0.050-inch compression thickness, delivering the exact sealing surface required for tight, leak-free combustion chamber closure. Built from copper construction, this gasket is designed to withstand the thermal cycling and combustion pressures inherent to high-performance and stock LS engine applications.

The 0.050-inch thickness specification is critical for achieving proper compression ratios and combustion chamber volume matching—a dimension that directly impacts ignition timing, peak cylinder pressure, and overall engine efficiency. Copper construction provides superior thermal conductivity compared to composite materials, promoting even heat dissipation across the cylinder head and block interface. The left-hand (driver-side) configuration ensures proper fitment on the corresponding bank of a GM LS engine, where precision bore sizing and gasket thickness are non-negotiable for preventing combustion gas bypass and coolant leakage.

This gasket is intended for engine builders, performance tuners, and technicians rebuilding or refreshing LS-series powerplants—whether naturally aspirated, turbocharged, or supercharged configurations. It addresses the foundational requirement of any LS engine overhaul: establishing a reliable, repeatable seal that maintains compression integrity over hundreds of heat cycles. The SCE Gaskets Titan series is recognized within the LS engine community for consistent quality across OEM and aftermarket builds, making this a standard specification for shops maintaining strict attention to head gasket sealing performance.

GM LS engine gasket replacement is routine maintenance for high-mileage cores and mandatory during any cylinder head work. Selecting the correct bore diameter and compression thickness is essential—mismatched gaskets introduce combustion leakage, oil seeping, and coolant intrusion, any of which can compromise engine longevity. The Titan Copper series delivers the repeatability required by professional rebuilders and the reliability demanded by weekend drag racers alike.
