Application: Datsun A-14 12pt
Part Number: 202-4203
Description:
It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants.
Simply stated, there is not a better stud setup on the market today.
ARP uses a premium grade 8740 alloy that is rated far superior to aircraft quality. Each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi.
ARP studs are thread rolled after heat-treat, which gives them 10 times better fatigue strength than those studs that are threaded prior to heat treat. You will also note that ARP offers specially undercut studs for several engines. This procedure (done only to shorter studs) more equalizes the stretch of both studs, which makes for a more consistent clamping force and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing.
Clearly, they are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.
