ARP Head Studs (2001-2015 LB7-LML)

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 only uses Premium Grade 8740 Alloy and a Proprietary ARP2000 Alloy that are rated far Superior to "Aircraft" quality alloy steels. Secondly, each stud is placed vertically into special racks and precisely heat-treated to 200,000 psi for the 8740 material and 220,000 psi for the ARP2000 material. Following heat-treat, each stud is centerless ground to make sure it is as close to perfectly concentric as possible. This procdure involves about ten very slight cuts and results in an exceptionally straight part.

ARP cylinder Head Studs are the clear favorite among top professional engine builders in nearly every form of motor sports. ARP uses a premium grade 8740 alloy that is rated superior to aircraft quality. Then each stud is specially heat treated in a vertical fixture that insures complete heat penetration. After heat treating the studs are centerless ground for precise concentricity, and then the threads are rolled which gives them ten times better fatigue strength than competitor's studs. It costs more to do it this way and it is very hard on the tooling but the results are well worth the extra expense. ARP stud kits are available for almost every domestic and import application and you just won't find a better product on the market from any other source.
