Z20LEx ARP Head Stud Kit - 209-4301
It's for good reason that virtually EVERY top engine builder relies on ARP Pro-Series head studs for all out competition powerplants.
Simply stated, there's not a better set up on the market today. ARP uses premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then each stud is placed vertically in special racks and 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. ARP studs are thread-rolled after heat treating which gives them 1000% better fatigue strength than those threaded prior to heat treating.
These premium quality chrome moly head stud kits are available for a variety of domestic, diesel, and import applications.
