ARP Head Stud Kit Dodge Cummins 5.9L/6.7L 24V '98-present
As a favorite among top professional engine builders and racers, the ARP cylinder head studs use only the best premium grade 8740 alloy with heat-treated vertical fixtures, insuring total heat penetration. This 8740 alloy is actually rated better than aircraft quality and the studs are centerless ground for precise concentricity. What also sets them apart is that the threads are rolled ten times, allowing for much better fatigue strength. While this doesn't put ARP head studs as the cheapest on the market, it does ensure the best possible quality for the product, so you can buy with confidence.
