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. Includes: Set of 10 Studs, Washers & Nuts; ARP Assembly lube included. We recommend these head studs as cheap insurance for anyone running 25-30psi boost. Show more
