ARP Cylinder Stud and Nut Kit Fasteners V6 Ford Duratec 2.5 & 3.0

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 200,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers. Also Remember, studs provide more accurate and consistent torque loading.

ARP Head Stud Kits 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

Fits all V6 2.5 & 3.0 liter Ford Duratec motors (Noble M400, Rossion Q1, Ford Contour, Ford Mondeo, Mercury Cougars, etc)
