1. Apply thread sealant to the air fitting
and screw it into the air spring.
Assemble the upper cup bracket to the
air spring, using 3/8” Nylok nuts and flat
washers. Thread the 8” stud into nut
welded to the bottom of the cup. Bolt
the lower cup to the bottom of the air
spring using a 3/8” x 3/4" bolt, flat
washer and lock washer.
2. Place the assembly up into the
upper coil spring pocket; the stud will go
though the factory shock hole. Fasten
with a 7/16” Nylok nut and flat washer.
Note: The airline must also be routed at
this time.
3. Reattach the lower arm to the
spindle. The lower cup is not attached
to the lower arm; it will simply sit in the
coil spring pocket.

*** Must Use RideTech Front Shock Kit ***
4. Make sure the air spring does not
rub on anything through full
suspension travel. This will damage
the air spring and is not a
warrantable situation. Although it is
acceptable to allow it to touch the lower
control arm when fully deflated.
5. The final step is to have the vehicle
realigned. You will want to have this
done at ride height. Ride height is
determined by air spring height. This
spring should be approximately 4 ¾”
tall, which should occur around 85-100
psi. This will vary to driver preference
and vehicle weight.

ARC4000 Compressor System Instructions
These are some general guidelines to follow when installing your new RidePro air control system.
Depending on the vehicle there are many different ways to plumb the system. Start out by
planning a lay out of where you want everything to be mounted. Typically we try to keep the
compressor, solenoids, tank, and sending units in a central location, but they can be separated to
suit your needs.
Mounting the Compressor/ Pressure Switch
Remove the negative battery cable before beginning installation.
All of our compressors are sealed for moisture and dust resistance so they can be mounted
anywhere on the vehicle. Although it is best to mount it in a place out of direct contact with
rain and snow. It is OK to mount it underneath the vehicle but keep it inside the frame rails
away from water and debris thrown off the tire.
This is a dry compressor; therefore it is maintenance free and can be mounted in any
position.
It is best if mounted to something solid to reduce vibration and noise. If mounting it to
sheet metal or the bed of a truck, use sound deadening material between the compressor
and the mounting surface.
Use the rubber grommets supplied on the feet of the compressor to reduce vibration.
A template is supplied to aid in drilling the holes. Check template with compressor before
drilling the holes.
Apply thread sealant to the pressure switch and compressor T and screw into the tank.
One spade of the pressure switch will connect to power the other to the red wire on the
compressor.
Mounting the Air Tank
The air tank can be mounted anywhere on the vehicle in any position.
A template is supplied to aid in drilling the holes. Check the template with the tank before
drilling the holes.
If your air system is used frequently you may want to remove the tank once a season to
drain any excessive accumulation of water.
Mounting the RidePro Air Valves
The valves, like the compressor, are sealed and can be mounted in the same locations.
Although if the vehicle will be exposed to freezing temperatures it is a good idea to mount
them in the engine bay if possible to reduce the possibility of freezing.
They can be mounted in any position.
Mount the valves higher than the tank to avoid moisture build up. This could cause the air
pressure sensors to give a faulty reading.
Attach the ground strap to a good, clean ground (preferably the frame).
The exhaust port will be left open.
The valve is held closed with the pressure in the tank. If tank pressure drops below air
spring pressure they will equalize deflating all 4 air springs.
Wiring Harness
The red wire on the harness will connect to 12 v.
The gray wire will then supply the gauge light 12v. Or the gauge light can be powered with
illumination.
Routing the Airline and Fittings
Make all airline cuts with a razor or tubing cutter. It must be clean and straight or it will not
seal.
All fittings are DOT approved push-to-connect style. They are very simple to use and are
reusable. Firmly push the airline into the fitting to attach. To release the airline pull the
collar on the fitting back towards the fitting and pull the airline out.
Use thread sealant on all fittings.
Do not over tighten the fittings. This could result in breaking the fitting or damaging the air
spring.
All of our airlines are DOT approved so they are very strong. But keep them away from
any sharp edges. Also when passing through a hole in the frame use a grommet.
Keep away from intense heat including mufflers and exhaust manifolds.
Use zip ties or other fasteners to secure the airline.
