NISSAN GT-R R35 COMPOSITE HEAD GASKET WITH COPPER RINGS 1.2MM

VR38DETT Combustion Sealing | Composite Head Gasket with Copper Rings

High-boost VR38DETT engines often suffer from "head lifting," where standard gaskets fail under extreme cylinder pressure. The SZM Composite Gasket is engineered to solve this bottleneck using high-precision copper fire rings. This addresses the problem of combustion leakage by allowing the rings to "bite" into the mating surfaces, providing a validated seal for higher HP builds. The 1.2mm thickness is validated to maintain optimal compression after resurfacing.
