• It 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.
