Stud Kit for ARP 250-4202

Designed for the (03-05) Ford F350, the ARP Supderduty 6.0L Diesel head studs are a popular choice among leading Sport Compact/Import racers. 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's premium grade 8740 alloy studs, rated far superior to "aircraft" quality, are the go-to solution.

Each ARP stud is precisely heat-treated to 200,000 psi and then centerless ground to ensure exceptional concentricity and straightness. This meticulous manufacturing process, involving about ten very slight cuts, results in a part that is far superior to lesser quality studs that are merely thread rolled in bar stock form, often before heat-treatment when the material is easier to machine.

The attention to detail in ARP's manufacturing process pays dividends in the final product. Gaskets and cylinder heads literally glide into position and are perfectly aligned when using ARP studs, something that won't happen with inferior quality head studs. Additionally, ARP studs are thread rolled after heat-treat, giving them about 1000% (or ten times) better fatigue strength than those studs that are threaded prior to heat-treat.

For certain engines, ARP offers specially undercut studs. This procedure, done only to the shorter studs, more evenly distributes the "stretch" of both studs, resulting in a more consistent clamping force. This helps compensate for head gasket compression when the head is installed, preventing blown head gaskets and ensuring optimum sealing.

The ARP Supderduty 6.0L Diesel head studs come with a black oxide finish and are designed to be a vehicle-specific fit. The package weight is 5.724 kilograms, ensuring a secure and reliable installation for your high-performance build.
