ARP 8740 CHROME MOLY:
Until the development of today’s
modern alloys, chrome
moly was popularly considered
a high strength material.
Now viewed as only moderate
strength, 8740 chrome
moly is seen as a good tough
steel, with adequate fatigue
properties for most racing
applications, but only if the
threads are rolled after heattreatment,
as is the standard
ARP production practice.
Typically, chrome moly is
classified as a quench and
temper steel, that can be
heat-treated to deliver tensile
strengths between 180,000
and 210,000 PSI.

ARP2000®:
An exclusive, hybrid-alloy
developed to deliver superior
strength and better fatigue
properties. While 8740 and
ARP2000 share similar
characteristics – ARP2000 is
capable of achieving clamp
loads in the 215,000-220,000
PSI range. ARP2000 is used
widely in short track and
drag racing as an up-grade
from 8740 chrome moly in
both steel and aluminum
rods. Stress corrosion and
hydrogen embrittlement
are typically not a problem,
providing care is taken
during installation.

ARP L19:
This is a premium steel
that is processed to deliver
superior strength and fatigue
properties. L19 is a very high
strength material compared
to 8740 and ARP2000 and
is capable of delivering
clamp loads in the 230,000-
260,000 PSI range. It is
primarily used in short track
and drag racing applications
where inertia loads exceed
the clamping capability of
ARP2000. Like most high
strength, quench and temper
steels – L19 requires special
care during manufacturing
to avoid hydrogen embrittlement.
This material is easily
contaminated and subject
to stress corrosion. It must
be kept well-oiled and not
exposed to moisture.
