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.

Quick and easy peace of mind

Easy to install, instructions very easy to follow, and it’s a peace of mind knowing that it’s one less fail point in the build


You are 100% right the ARP Head Studs give you peace of mind! They wont fail and the premium grade 8740 alloy ensures no stretching under high boost! Definitely a must when performing a build! Thank you for your 5 Star Review!


The mechanic liked them

Don’t know that much about head studs but I know the shop working on my car said I did good and said I was lucky to find them, no one has them. Subimods did, walked in empty handed left with a fist full.


ARP Head Studs the only way to go when replacing head studs. They are a must when your heads are off! Thank you for the 5 Stars,
