STEP 7: Install the two male 90-
degree elbow fittings into the inlet
ports on the compressor. Use thread
sealant on the ends being inserted
into the compressor to ensure a
tight seal.
STEP 8: Install the other male 90-
degree fitting into the outlet port of
the compressor. Make sure to use
thread sealant on this as well.
STEP 9: It’s time to put the compressor
in! Fit the compressor up into the
intended space and line up the compressor
bracket with the spacer on
the firewall and the corresponding
hole with the master cylinder stud
above the compressor. (There are two
different mounting holes depending
on whether the kit is being installed in
a Wrangler or a Gladiator.) Secure into
place with the nuts. There is not
much clearance, you will need to pull
the compressor bracket away from
the firewall about 1/4” to get the nuts
on. Tighten with a wrench.
You can use the additional mounting
hole and the Gladiator specific
mounting hole to mount an ARB
manifold for air lockers. In a Gladiator,
you can install the manifold using
the additional mounting hole and the
Wrangler specific mounting hole. So,
in both Wrangler and Gladiator models
you can mount the ARB manifold
directly to the mounting bracket.
STEP 10: Reinstall the upper
shock bolt.
STEP 11: Adjust the wires up and out
of the way making sure nothing is
being pinched. You can use zip ties to
secure them in a safe spot.
How well does it perform in this
little space? How does it not overheat?
The included heat shield protects
it from the catalytic converter
which gets to almost 2000 degrees.
The catalytic converter actually has a
heat shield of its own to keep the
temperature inside the exhaust and
there is a 3” air gap to the catalytic
converter which helps a lot. During
development they did an 8-hour
straight test with a slow leak on the
compressor where it was having to
cycle on and off with the jeep running
and the temperature only got about
10 degrees warmer than doing the
same test on the bench. The heat
performance is actually very good.
The heat shield reflects a large
amount of heat back from the catalytic
converter. That’s also why the fan
is in the back where it can take cold
air in from the bottom of the fender
well. There’s an air gap there. It’s high
enough up where it is protected from
the elements as well. It’s actually a
very good home for it. Now let’s move
up top and start bringing stuff down
to it. It’s easiest to bring all the tubing
and things like that down to meet it
instead of trying to route them up.
STEP 12: Remove the two nuts from
the coolant reservoir and shimmy it
up and off, then open up the wire
loom compartment along the firewall.
Compressor Wiring Harness
STEP 13: Grab your ARB wiring
harness and plug it into the compressor.
You will then thread the ARB
wiring harness inside here with the
factory wiring in the wire loom compartment,
this keeps it looking stock
and clean.
This is a great place to run any
wiring you might have, power steps or
lights. That way you only have to go in
there once.
