ARP Head Studs
Audi/VW
INCLUDES: Premium parallel
ground washers
Obtaining optimum cylinder head-to-block sealing is
especially critical in small displacement engines using high
comp pistons or power adders like turbochargers, nitrous oxide and
superchargers.
ARP uses premium grade 8740 alloy
that is rated far superior to “aircraft” quality. Each stud is
precisely heat-treated to 200,000 psi. Following heat-treat, each
stud is centerless ground to make it as close to perfectly concentric
as possible. This involves about ten very slight
cuts and results in an exceptionally straight part (lesser quality studs are not even centerless ground
– the material is thread rolled in bar stock form, usually prior to
heat-treat).
Because ARP studs are manufactured to such exacting tolerances, 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 1000% (that’s ten times), better fatigue strength than those
studs that are threaded prior to heat-treat.
Undercut Studs: equalizes the “stretch” of both studs, which makes for a
more consistent clamping force – one that compensates for head
gasket compression when the head is installed. This helps prevent
blown head gaskets, and assures optimum sealing! (available for select
applications only). |
