GM LT1 U/S Head Gasket (1 Piece)

The MR. GASKET GM LT1 U/S Head Gasket (1 Piece) is a premium cylinder head gasket engineered for GM LT-Series engines from 1992–1997. This Ultra-Seal gasket combines rubber-coated steel and graphite construction to deliver superior sealing performance while managing combustion pressures in high-performance applications. Designed specifically for engines with a 4.110-inch bore and 0.026-inch compression thickness, it maintains critical compression integrity across the engine's operating range.

The hybrid rubber-coated steel and graphite composition provides multi-directional sealing at the head-to-block interface, preventing coolant and combustion gas leakage while accommodating thermal expansion cycles. The 0.026-inch thickness is a precision specification that maintains the engine's intended compression ratio without requiring shim adjustments. GM LT-Series engines—which include the LT1 and LT4—demand gaskets that can withstand elevated combustion temperatures and pressure spikes. This gasket is engineered to that standard and is sold as a single piece for engines requiring replacement or rebuild work.

This gasket suits owners and rebuilders working on fifth-generation Chevrolet Camaros, Firebirds, or any platform running the LT-Series engine family during that production window. Whether performing routine maintenance, addressing a leaking gasket, or completing a full engine overhaul, this MR. GASKET component ensures reliable sealing and extended service life. The proven Ultra-Seal design has earned trust in street, performance, and racing applications where gasket durability is non-negotiable. Part number 5716G; UPC 084041022726.
