Freedom Off-Road C100 Compressor Kit #FO-C100-KIT




The installation of this kit does not change the Gross Vehicle Weight Rating (GVWR) or payload capacity of the vehicle. Check your owner’s manual and DO NOT exceed maximum load capacities for your vehicle.



NOTE: The compressor can essentially be mounted in any position and will still function properly. It should be mounted in such that it is well protected from the elements, water splash, snow/ice build-up, etc. Avoid any high heat areas as this will cause premature failure of any rubber and polymer components. Keep all air lines a minimum of 12in away from any heat source. If you choose to mount the compressor outside of the vehicle, you can snorkel the air intake filter to the inside of the vehicle. If remote mount is not included/possible orient the compressor so that the intake filter can drain easily.


  1. Mount the compressor securely inside the vehicle if possible. The compressor can be mounted in any position- vertical, upside down, sideways, etc
  2. If mounted outside of the vehicle, keep away from any heat sources and exposure to the elements (see NOTE above)
  3. Make sure compressor is securely mounted as it will tend to loosen during operation.



  1. Find a easily accessible and sturdy mounting location for the gauge panel that has a rigid surface that will provide a solid mounting surface. (i.e. under the dash, glove box, center console)
  2. Use the gauge panel as a template, mark the screw hole locations. It helps to use a center punch to keep the drill from slipping on interior panels, then drill two 1/8in diameter holes.
  3. Position the gauge over the newly drilled holes and secure into position with the 2 provided self-tapping screws.


  1. Use a hose cutter or a razor blade to cut the air line, and make sure all cuts are nice and square. Scissors or dykes/wire cutters will not cut it properly but instead crush the line and can compromise making proper seals.
  2. Push the air line onto the barb fitting on the compressor making sure that the line covers all barbs. A small amount of water and pushing with a slight circular motion will ease the line onto the barb fitting.
  3. Cut the air line roughly 1 foot from the compressor and insert the T-fitting in the line.
  4. Now run however much airline is required to reach the air shocks or air bags. From the other side of the T-fitting run however much air line is required to reach the barb fitting on the back of the gauge panel.
  5. There will be a section of airline coming from each bag or shock and you will connect these to the other provided T-fitting
  6. Connect the air line coming from the compressor T-fitting to the T-Fitting that runs to the air bags/ air shocks



  1. Connect the red wire to the red compressor POWER lead. Run the wire through the firewall and connect it to a terminal on the back of the ON/OFF switch on the gauge panel.
  2. Attach the ground, black, wire on the compressor to an adequate ground source on the chassis. (metal fenderwell, frame, etc) It may be necessary to sand the paint or coating off to reach bare metal to get a solid ground.
  3. Using the white wire you now will add the in-line fuse. You can add it anywhere in the white wire that will make it easily accessible using the butt connectors. One end of the wire you add a female spade connector and connect it to the other terminal on the ON/OFF switch on the gauge panel.
  4. The other end of the wire will be run to the vehicle’s fuse box. You will need to find a terminal with an amperage rating equal to or higher than the 20A in-line fuse. Use a test light to determine which open terminal (accessory, etc) works only when the key is in the “ON” or “ACCESSORY” position. You can use the Quick Splice connector to tap into the wire coming from the side of the fuse that is powered once the key is in the appropriate position. Another option is using the fuse adapters provided with the kits. There are two versions for the blade type fuses, one for the mini blade type, and one for the standard size blade type. See the diagram for how they are used.
  5. Once everything is connected you will need to test the circuit. Check the air compressor by pressing the ON/OFF button. If the compressor operates make sure it builds pressure in the system and then use a mix of soapy water to test for any leaks. If the compressor doe NOT run, you will use a test light to determine that the ON/OFF switch is receiving power to both sides of the switch. Then make sure the ground wire is providing a sufficient ground.



  1. Always follow the instructions provided with your air spring/ air shock kit. Maintain at least the minimum recommended pressure and never exceed the maximum recommended pressure.
  2. To increase pressure push the ON/OFF switch to start the compressor and as soon as it reaches the desired pressure move switch the ON/OFF switch to the OFF position. NOTE: Run compressor in 4 minute intervals to allow the compressor to cool down.
  3. To reduce pressure in the system remove the cap from the Schrader valve located on the gauge panel and press the extended part of the cap into the valve stem which will release the air until you reach your desired pressure. Once the desired pressure is reached thread cap back on.


  1. Compressor does not run- check all wiring making sure you have power and a good ground. Check all fuses making sure none are blown.
  2. Compressor runs but pressure does not build or system loses pressure- Test all air line connections with a soapy water solution to determine where air leaks are located. Replace air line if necessary. Also check the valve core used for deflation, and tighten if leaking.
