Construction & Design

The HKS head gasket kit features a grommet-type design that enhances sealing performance over traditional composite or metal head gaskets. The gasket's 1.6mm thickness strikes a balance between strength and flexibility, accommodating thermal expansion while maintaining a tight seal. Manufactured from premium materials, the gasket resists warping, cracking, and degradation caused by high temperatures and aggressive tuning. The grommet design incorporates reinforced metal rings around the cylinder openings, ensuring a secure fit and preventing gasket failure during high boost or extended use. This meticulous construction ensures consistent sealing, reduces the likelihood of head gasket leaks, and supports the engine's overall reliability and performance.

Installation & Fitment

The HKS Grommet Type Head Gasket Kit is a direct replacement for the OEM head gasket on the Nissan Skyline GT-R RB26DETT engines. Installation requires standard engine rebuild procedures, including removing the cylinder head, cleaning mating surfaces, and torquing the head bolts to the manufacturer’s specifications. No special modifications or tuning are necessary beyond proper installation. Due to its OEM-like fitment and high-quality materials, the gasket set simplifies the rebuild process and ensures a secure, leak-free seal once installed. It is recommended to follow all torque specifications and sequence to achieve optimal sealing and longevity.
