Supertech Nissan RB28 87.5mm Bore 0.059in (1.5mm) Thick MLS Head Gasket

This is a Supertech Multi-Layer Steel (MLS) head gasket specifically made for Nissan RB28 engines with an 87.5mm bore. It's 0.059 inches (1.5mm) thick, designed to seal the combustion chamber and coolant passages between your engine block and cylinder head. A well-built head gasket is crucial for maintaining proper compression and preventing coolant or oil leaks, especially in modified or high-performance applications where stock gaskets might not hold up.

Supertech uses a multi-layer steel construction for this gasket, which offers improved strength and sealing capabilities compared to older composite designs. The multiple steel layers, combined with a specialized coating, help it conform to the mating surfaces of the block and head, creating a strong seal that resists blowout under pressure. This particular gasket is 1.5mm thick, which is a common thickness for builds that might involve slight block or head resurfacing, or for achieving a specific compression ratio when paired with other engine components.

When installing this gasket, ensure both your engine block deck and cylinder head surfaces are clean, flat, and free of any debris or old gasket material. Always refer to the manufacturer's installation instructions for proper torque sequences and specifications, as these are critical for achieving a reliable seal with an MLS gasket.
