NASCAR SPECIALTIES
Because races can be won or lost in the pits, the engineers at ARP
set about to create the ultimate oval track competition wheel stud
that facilitates accurate wheel positioning and quicker release/tight-
ening of lug nuts. ARP’s new “Speed Studs” (and companion “Speed
Nuts”) are so good that a large number of NASCAR teams in Sprint
Cup, Nationwide and Camping World Truck Series use them exclu-
sively. They’re made from heat-treated
200,000 psi
chrome moly
steel and feature precision J-form threads (formed after heat-treat for
improved fatigue strength), exclusive nut-starter and bullet shape radius
that all but eliminates cross-threading, shot-peening, special baked-on
dry film lubricant (reduces possibility of galling and assures consis-
tent clamp loads), and double magnaflux inspection. A new head
design is employed that fits the registers of all popular hubs without
grinding, and studs are available in 31 underhead lengths to provide you
with the optimum thread engagement for your particular setup. The
finest studs available!
SPEED STUDS
™
Designed for professional racing environments where split-
second improvements in pit stop times can make the winning
difference, and “unbustable” reliability is an absolute must. ARP’s
Speed Nuts feature a profiled nut face for easy installation, quick-
er socket releases and resistance to jamming. They’re made from
premium heat-treated chrome moly that’s nominally rated at
200,000 psi
tensile strength, shot-peened to remove stress risers
and double magnafluxed after heat-treating and thread-forming
to assure 100% metallurgical integrity. Coated with Alumotef
III gold coating. Speed Nuts are ready for “instant” use (thread
chasing not required).
