ARP 247-4202 Stud Kit (Cummins 5.9L Dsl 24V) Built for the (98-02) Dodge Ram 2500
Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers. That's why ARP head studs are popular among leading Sport Compact/Import racers. ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality, and each stud is precisely heat-treated to 200,000 psi. Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible, a procedure that involves about ten very slight cuts and results in an exceptionally straight part. In contrast, lesser quality studs are not even centerless ground, with the material thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, gaskets and cylinder heads literally glide into position and are perfectly aligned, something that won't happen with inferior quality head studs.
ARP studs 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. ARP also offers specially undercut studs for several engines, a procedure (done only to the shorter studs) that more equalizes the "stretch" of both studs, making for a more consistent clamping force that compensates for head gasket compression when the head is installed. This helps prevent blown head gaskets and assures optimum sealing.
