ARP uses a premium grade 8740 alloy for their 03-05 Doge Neon SRT-4 head studs. Each stud is placed vertically in special racks and precisely heat-treated to 190,000 psi. This heat treating procedure ensures complete heat penetration and the results are far superior to head studs from other manufacturers who just dump pieces in a basket and hope for the best. Following heat treatment process, each 03-05 SRT-4 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 bolt.
Because ARP studs for the 2003-2005 Dodge Neon SRT-4 are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads glide into position and are perfectly aligned - something that won't happen with inferior quality head studs. ARP studs are thread rolled after heat-treating, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treating (a very common industry practice). It costs ARP a lot more to make their SRT-4 head studs this way, because it's tough on tooling, but the results are well worth the extra effort. Clearly, ARP high performance 03-05 Dodge Neon SRT-4 head studs are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.
