Benefits of HKS Head Studs:
• By using bottomed type stud bolts, the active threads on the block side are longer and the stress is dispersed, allowing for higher axial force to be endured.
• ARP' Custom Age 625 Plus material gives the highest tensile strength, excellent endurance cycle life and corrosion resistance.
