4.100 MLX Head Gasket .051 - GM LS 6.2L LH

The 4.100 MLX Head Gasket .051 - GM LS 6.2L LH from Cometic Gaskets is a precision cylinder head gasket engineered for high-output LS engine platforms in both OEM and custom builds. This gasket serves operators, mechanics, and performance builders who demand reliability under sustained load—whether in armored platform powerplants, generator sets, or tactical vehicle applications. The MLX designation indicates a premium composite gasket design built to withstand the thermal cycling and pressure spikes inherent in demanding duty cycles.

At .051 inches thickness, this head gasket is calibrated for the GM LS 6.2L architecture, providing controlled compression sealing without over-compression that could compromise valve timing or combustion efficiency. The MLX composite construction resists delamination, coolant migration, and blowby—critical failure modes in high-duty applications where engine shutdown is not an option. Left-hand (LH) orientation ensures proper fitment on the driver's side cylinder head, with the gasket's integral bead architecture maintaining consistent clamp load across thermal extremes. Cometic's manufacturing tolerances guarantee no loss of seal integrity during extended operation at elevated temperatures or rapid thermal transitions common in tactical and emergency-response vehicles.

Field users and qualified technicians will recognize this gasket as essential for any LS 6.2L head work, including overhaul, performance modification, or preventive maintenance on platforms requiring mission-critical uptime. Installation requires OEM torque specifications and proper surface preparation; failure to follow manufacturer protocols will void performance guarantees. The gasket's compact footprint (9.7 x 23.9 inches) matches factory specifications precisely, ensuring compatibility with stock or aftermarket cylinder heads on 6.2L Gen IV and Gen V LS platforms commonly found in commercial, industrial, and specialized vehicle applications.
