Description
Eliminate Blown Head Gaskets on V18 Industrial Platforms
The aftermarket cylinder head gasket kit matching OEM 4955812 is exclusively developed for the massive 78-liter QSK78 engine architecture. Operating 400-ton mining haul trucks and continuous megawatt power generators demands zero-tolerance combustion containment. Constructed from a premium Multi-Layer Steel (MLS) matrix, this gasket prevents critical blow-by and cross-contamination between oil, coolant, and combustion chambers under severe load cycles.
Technical Sealing Specifications
To guarantee exact fitment and structural integrity during engine overhauls, the 4955812 replacement kit is manufactured to stringent dimensional and thermal tolerances.
