SB BB CHRYS 318 440 WEDGE MAINBOLTS 2 BOLT MAIN

Description

Far superior to any other
main bolt kit offered for use
in competition engines, ARP
main bolts are designed to
meet the exacting standards
and demands of professional
engine builders. Forged from
8740 chrome moly, all bolts
feature generous under-head
radius and rolled threads for
the utmost reliability. The
threads are rolled after
heat-treating, which makes
them about 1000% longer
fatigue life than most main
bolts, which are threaded
prior to heat-treating.
Available in the popular
High Performance Series,
which at a nominal rating of
180,000 psi, is a premium
replacement for OEM
fasteners, or the 200,000 psi
nominal rated Pro Series
, application-specific
main bolts with reduced
wrenching head and are
designed for use in
competition applications.
Parallel-ground, hardened
washers are included with
each kit
