Looking for a cheaper alternate that is built in the USA that is just as strong?
ARP Pro Series cylinder 247-4203 12mm Headstud Kit are cold-forged to ensure molecular integrity. They are heat-treated prior to thread rolling and machining, and all kits come complete with hardened parallel washers for an even load distribution and accurate torque readings.
It is for good reason that virtually every top professional engine builder relies on ARP Pro Series 247-4203 12mm Headstud Kit for their all-out competition powerplants. Moreover, there’s not a better stud setup on the market today. 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 220,000 psi.
ARP studs are thread rolled after heat-treat, which gives them about 1000% (thats ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). What’s more you wont find a better quality stud on the market from any other source.
