Lamspeed Racing ARP Custom Aged 625+ Pro Series Headstuds - Toyota GR Yaris / Corolla G16E-GTS
Details:
For applications where you have turned the boost right up over 30psi and plan to keep the head from lifting. This is the first thing that occurs from our testing when pushing the limits from when we set the World Record in our GR Yaris running a 10.5 @ 131mph to then setting the GR Yaris record around Sydney Motorsport Park at the 2022 World Time Attack Challenge with a 1.36.8
We are the first to develop and put into production an aftermarket head stud solution by taking our own measurements to ensure the studs are of the correct length so that they bottom out on the block, the factory bolts do not.
These Custom Aged 625+ headstuds are manufactured specifically for us by ARP (The industry's standard) and are much stronger than the typical 8740 chromoly, H13 and H11 tool steel and yields a tensile strength of 260,000 psi.
Features:
- Hex broach feature on the stud allows for easy installation.
- ARP Custom Aged 625 material with ARP hardened washers and multipoint nuts
- Direct OEM replacement, no modifications.
