ARP 90-01 Integra Head Stud Kit B18A/B18BIt is for good reason that virtually every top professional engine builder relies on ARP. Pro Series head studs for their all-out competition powerplants. Simply stated, there's not a better stud setup on the market today.For openers, 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 190,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight ARP. studs are thread rolled after heat-treat, which gives them about 1000% (that is ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). Premium quality heat-treated 8740 chrome moly steel head stud kits are available for most every domestic and import application. You won't find a better quality stud on the market from any other source. Look for ARP. stamped on each stud as your assurance of quality. This item fits .
