ARP - 156-4301 - 8740 Chrome Moly - Ford - Automotive - Head Studs
It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition power plants. Simply stated, there's not a better stud setup on the market today.
ARP only uses premium grade 8740 alloy, ARP2000 alloy, and makes the Custom Age 625+ head stud kits which are available for most domestic and import applications.
Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground – the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned – something that won’t happen with inferior quality head studs.
You won't find a better quality stud on the market from any other source. Check out our selection of ARP bolts at Horsepower Direct today!
