Description
Due
to
head
lift
issues
at
high
WHP,
additional
clamping
force
is
needed.
While
standard
ARP
studs
can
be
torqued
down
to
65-70ft/lbs,
these
ARP
made
with
262,000psi
tensile
strength
L19
steel
can
be
torqued
down
to
90-95
ft/lbs
easily,
without
breaking
the
stud.
These
are
a
direct
drop
in
replacement,
and
require
no
special
block
modifications
or
machining.
We
feel
so
strongly
about
these
extreme
duty
L19
studs,
that
we
will
no
longer
carry
the
standard
ARP
head
stud,
as
they
have
proven
unreliable
beyond
525whp,
due
to
insufficient
clamping
force.
Please
note:
ARP
states
that
it's
very
important
not
to
touch
L19
studs
with
your
bare
hands;
always
use
gloves
when
handling.
