XP-Series
Rod
Bearing
Set
(CR6676XP)
by
King
Engine
Bearings®.
pMax
Black™
is
a
unique
tri-metal
structure
for
race
applications.
The
overlay
is
strengthened
by
a
proprietary
nano-scaled
hardening
process
that
modifies
the
molecular
structure
and
creates
a
black
fatigue-resistant
shield.

Successful
race
engine
builders
are
constantly
pushing
the
limits
of
load
capacity
to
new
levels.
Race
bearings
today
inevitably
need
to
match
these
demands
with
more
competitive
bearings.
At
King
Racing
they
met
the
challenge
with
the
XP
high
performance
bearings
series.
The
XP
series
is
a
line
of
bearings
with
advanced
metallurgical
and
geometric
technologies
that
meet
extreme
performance
loads.
It
was
developed
for
all
performance
applications
that
use
forged
steel
aftermarket
crankshafts
and
produce
high
loads
for
extended
periods.
King
Racing’s
XP
series
features
pMax
Black™,
a
unique
tri-metal
structure
that
is
24%
harder
than
any
other
conventional
tri-metal
race
bearing.
pMax
Black™
together
with
the
XP
geometric
features
are
the
ideal
combination
for
performance
racing.
