Head Gasket Set with MLS Gaskets (304 Stainless) FIT 2010-2017 Chevy Equinox Malibu GMC Terrain Buick 2.4L Ecotec, Replaces HS54874 HS26517PT (Head Bolts Not Included) - 1 Set
Precise Fitment Protocol: FIT 2010-2017 Chevrolet Equinox / Captiva Sport / Malibu / Impala 2.4L, FIT 2010-2017 GMC Terrain 2.4L, FIT 2010-2017 Buick LaCrosse / Regal / Verano 2.4L. Engine: GM Ecotec L4 (LAF, LEA, LUK). Non-Compatibility Notice: Engineered for 2.4L L4 only; will NOT fit 2.0L Turbo or 2.5L engine architectures.
304 Stainless Multi-Layer Steel (MLS): Features a premium Multi-Layer Steel (MLS) head gasket constructed from 304 Stainless Steel with a physical 0.031-inch core thickness. This hardware is engineered to maintain a constant physical clamp load and support stable thermal geometry under the high-pressure combustion cycles of GM Direct Injection engines.
Integrated Upper Sealing Group: This comprehensive kit supplies intake and exhaust manifold gaskets, valve cover gaskets, and front camshaft seals for a complete top-end service. The gaskets feature pre-applied silicone beads designed to ensure a precise physical interface with factory machined engine surfaces without the requirement for extra RTV sealant.
Viton Thermal Integrity: Includes Viton valve stem seals engineered for a physical temperature resistance range of -40°C to 200°C (-40°F to 392°F). These components maintain chemical and thermal stability during high-RPM operational cycles, ensuring a consistent physical barrier for the internal valve train lubrication system.
Restoration of System Geometry: Engineered to address internal fluid resistance and resolve hydraulic instability. This refresh kit restores factory handling characteristics by providing a reinforced physical seal across all OE coolant, oil, and dowel ports, maintaining the integrity of the combustion chamber geometry for the 2.4L Ecotec platform.
