The HKS Head Gasket for the RB26DETT engine with an 88mm bore and 1.6mm thickness is engineered to deliver superior sealing performance under extreme conditions. Designed as a grommet type metal gasket, this advanced component greatly improves the limits of sealing by distributing pressure evenly across the cylinder head and block. Its reinforced structure reduces the risk of gasket failure, even under high boost, high heat, and the constant vibration that RB26 engines endure in performance driving.
This updated 1.6mm thickness is ideal for overhauls and rebuilds that require surface polishing, offering the necessary tolerance while maintaining precise compression characteristics. When paired with strengthened head bolts, the gasket provides exceptional sealing strength, ensuring stable combustion and long-term reliability. By addressing the uneven surface pressure and fluctuating contact gaps that occur in high-output engines, the HKS grommet gasket adapts to changing conditions, maintaining consistency and durability.
In addition to the head gasket itself, this kit includes exhaust manifold gaskets, intake manifold gasket, and throttle body gaskets, providing a comprehensive solution for complete sealing during installation. This makes it the perfect choice for enthusiasts and builders who demand OEM-level precision with race-proven reliability. Terra Firma Automotive proudly supplies this genuine HKS gasket, ensuring your Nissan Skyline GT-R’s RB26DETT engine receives the highest level of performance and protection available.
