ARP Pro Series Cylinder Head Stud Kit

Toyota GR Yaris & GR Corolla ARP Pro Series Head Stud Kit

Secure the top end of your G16E-GTS engine with the ARP Pro Series Cylinder Head Stud Kit. Trusted by the world’s elite engine builders, these studs are an essential upgrade for any high-boost Toyota GR Yaris or GR Corolla build. When increasing performance beyond factory levels, the superior clamping force provided by ARP ensures head gasket integrity and optimum engine sealing under extreme combustion pressures.

Every ARP stud is manufactured from premium grade 8740 chrome moly alloy, precisely heat-treated to 200,000 psi. Unlike inferior products, ARP studs are centreless ground after heat-treatment to ensure perfect concentricity. This exacting process allows cylinder heads and gaskets to glide into position with perfect alignment. Furthermore, the threads are rolled after heat-treat, resulting in up to 1000% better fatigue strength compared to standard studs.

For the G16E platform, these studs provide the consistent clamping force necessary to compensate for head gasket compression and prevent catastrophic failure during hard track or rally use. As a stockist of premium motorsport hardware, Chicane Australia recommends ARP for any serious performance engine assembly.
