ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi. 

ARP studs are thread rolled after heat-treat, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it's tough on tooling, but the results are well worth the extra effort.

While your in there.

Used these when building a long block. Extra piece of mind for a stage 3 tune.

Shad,

Using ARP Head Studs for Subaru Turbo Models during a long block build is a wise choice for added peace of mind, especially with a stage 3 tune. It is great to prioritize reliability and performance during such upgrades. We appreciate your 5 Star Review! Happy building!

Always use ARP

The quality of this hardware is top notch and always a good idea when running higher boost.

Zach,

Turbo cars are known for separating at the heads when more boost is introduced. The ARP 11mm Head studs are the best way to prevent this from happening! Thank you for your 5 Stars! Enjoy the added protection!
