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’s not a better stud setup
on the market today.
For openers, ARP only uses premium grade 8740 alloy and
a proprietary ARP2000® alloy that are rated far superior to “aircraft”
quality alloy steels. Secondly, each stud is placed vertically
into special racks and precisely heat-treated to 190,000 psi for
the 8740 material and 220,000 psi for the ARP2000® material.
This procedure ensures complete heat penetration and the results
are far superior to those lesser quality studs from other manufacturers
who just dump pieces in a basket and hope for the best.
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.
ARP studs are thread rolled after heat-treat, which gives them
about 2000% (that’s twenty times) better fatigue strength than
those studs that are threaded prior to heat-treat (a very common
industry practice). It costs a lot more to do it this way, because it’s
tough on tooling, but the results are well worth the extra effort.
You will also note that ARP offers specially undercut studs for
several engines. This procedure (done only to the 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!
Premium quality 8740 and ARP2000® head stud kits are available
for most domestic and import applications. You won’t find a
better quality stud on the market from any other source. Look for
ARP stamped on each stud as your assurance of quality.
Clearly, they are the best on the market today, and the favorite
of leading professional engine builders in all forms of racing.
