HKS 87-92 Supra MK3 1.2mm Bead Headgasket

This HKS bead head gasket measures 1.2mm thick and delivers strong sealing for high-boost applications on 1987-1992 Toyota Supra MK3 models equipped with the 7M-GTE engine. It replaces stock gaskets with a design that handles extreme cylinder pressures while maintaining combustion stability. Ideal for turbocharged builds seeking dependable head-to-block sealing.

Key Features

  • 1.2mm Thickness: Matches OEM specs for accurate compression ratios in 7M-GTE engines during high-boost setups.
  • Bead Rolled Design: Raised stainless steel bead creates tight seal against combustion gases up to 40psi boost levels.
  • Multi-Layer Steel Construction: Layers of SUS430 stainless and graphite resist heat over 1000°C and prevent blowouts.
  • Precise Bore Fit: 86mm bore diameter ensures perfect alignment on Supra MK3 cylinder heads without distortion.
  • Lightweight Build: Reduces reciprocating mass for quicker engine response in performance applications.

Product Notes

  • Pair with ARP head studs for optimal clamping force during installation.
  • Inspect head and block surfaces for flatness before use to ensure leak-free performance.
  • Ships flat in protective packaging to prevent bending or damage.

Installation Notes

  • Professional installation recommended.
  • Torque head bolts to HKS specs in 3 stages with moly paste on threads.
  • Compatible with factory head bolts if resurfaced but ARP studs preferred for boost over 20psi.
