22999-AT001

Strengthened head stud bolts for the GR Corolla and GR Yaris with the G16E-GTS engine are now available, offering enhanced sealing performance when paired with the already-available Grommet Head Gasket, designed for engines with high combustion pressure.

Vehicle Fitment:

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.
