Cylinder Head Stud Kit for Ford 2.3L EcoBoostIt is for good reason that virtually every top professional enginebuilder relies on ARP Pro Series head studs for their all out competitionpowerplants. Simply stated, theres not a better stud setupon the market today. For openers, ARP only uses premium grade 8740 alloy anda proprietary ARP2000 alloy that are rated far superior to aircraftquality alloy steels. Secondly, each stud is placed verticallyinto special racks and precisely heat treated to

The threads are rolled after heat-treating which gives them about 2000% better fatigue strength than most main bolts that are threaded prior to heat-treating

They run-in straight and true

premiumgrade aerospace chrome moly steel

with threads rolled after heat treat to ensure the optimum fatigue strength

This procedureinvolves about ten very slight cuts and results in an exceptionallystraight part

and precision J-form threads rolled after heat-treat to create a fastener that has threads 2000% stronger than others

They are both forged from aerospace alloy and heat-treated prior to thread rollingand machining

Available in both High Performance and Pro Series kits

ARP’s timing cover bolts are available in both polished stainless steel or black oxide finish chrome moly

then allow the nuts to be easily installed without the worry of cross-threading

They’re nominally rated at 180
