Engine Gasket
Seal high-pressure combustion chambers, eliminate oil and coolant leaks, and safeguard your internal compression numbers with our premium selection of heavy-duty ATV and UTV engine gaskets. Functioning as the critical micro-barrier between major structural engine castings, engine gaskets maintain isolated pathways for high-velocity cooling jackets, pressurized oil galleys, and cylinder combustion zones. Severe thermal expansion cycling, high-RPM vibrations, and detonation spikes put immense physical stress on mating mating surfaces, eventually causing factory composite seals to warp, weep fluid, or blow out completely. At CG ATV & UTV Parts Shop, we stock multi-layer steel (MLS) head gaskets, oil-resistant viton valve stem seals, durable rubber valve cover gaskets, and complete crankcase overhaul seal kits.
Our domestic fulfillment channels process and ship orders daily from strategic distribution hubs across the country to minimize your garage downtime. Whether you are conducting a routine top-end freshen-up or completing a total bottom-end case split after a crank failure, our components deliver exact dimensional sealing profiles. Lock in your engine’s compression and keep trail debris out of your internal lubrication paths.

Multi-Layer Steel (MLS) Technology vs. Combustion Blowouts & Deck Distortion
Standard composite or paper-faced gaskets struggle to survive the intense thermal expansion mismatch that occurs between aluminum cylinder heads and cast iron blocks during high-temperature operations. Our high-performance replacement ATV and UTV engine gaskets feature Multi-Layer Steel (MLS) construction, composed of individual layers of tempered spring steel coated with a micro-thin layer of specialized nitrile or Viton rubber. The outer layers utilize custom-embossed sealing beads that act as structural springs, maintaining absolute mechanical load against the sealing surfaces even when head bolts expand and relax under high combustion pressures.
To eliminate oil migration and vacuum leaks along the lower crankcase assemblies, our peripheral gaskets are cut from premium high-density synthetic fiber or molded from fuel-resistant fluorocarbon elastomers. This structural stability prevents the gasket material from creeping, relaxing, or extruding out under high bolt-clamping forces. Precision die-cut water and oil pass holes align exactly with original engine blueprints to prevent high-velocity fluid cavitation, ensuring unrestricted thermal transfer between engine sections.

Surface Deck Preparation, Torque-to-Yield Fastening, & Sealing Agent Guidelines
When installing a replacement engine gasket, never use wire wheels, metal scrapers, or aggressive abrasives on aluminum mating surfaces, as these tools easily gouge microscopic paths that cause immediate gasket weeping. Meticulously clean all old sealant residues using a chemical gasket remover and plastic scrapers until the surface is completely bare, then perform a final degreasing pass using aerosol brake cleaner. Check both the cylinder head and engine block surfaces for flatness using a precision machinist straightedge and feeler gauges to ensure warp tolerances are within factory specification. Always follow the manufacturer's specified bolt tightening sequence and multi-stage torque specs using a calibrated torque wrench, replacing torque-to-yield head bolts where required. Use high-temperature silicone RTV sealants only at designated case junctions or three-way split lines, applying a minimal bead to prevent excess silicone from breaking off inside and blocking small internal oil screens. For industrial material specification metrics on non-metallic gaskets and automotive sealing tests, refer to the International Organization for Standardization (ISO) Directory.
