We recommend that you install the air spring kit first per the instructions provided with the air spring kit.

1. Install the gauge panel. Select a convenient mounting location that has a rigid surface that will provide for a sturdy mounting surface. The bottom edge of the dash on either side of the steering wheel is a good location. Use the black self-tapping screws to attach the panel to the selected location.

2. Now install the compressor unit. Refer to the recommended compressor location list included with this kit. Hold the compressor in the recommended location and use the provided silver self-tapping screws to attach the mounting brackets to the vehicle. In some cases the mounting area does not allow enough room to use a drill to drive the screws in. It will be necessary to use the mounting brackets as a template to drill 13/64” holes through the frame first and then use a 7/16” nut driver to install self-tapping screws. NOTE: Attach the ground wire to one of the screws (Figure 1 & 5).

For box frames: In most cases the frame section will not be wide enough to mount the compressor legs flat to the rail. It may be necessary to bend the mounting brackets into a 90-degree angle to allow the brackets to attach to the side and bottom of the frame rail (Figure 7). The compressor mounting legs can be bent by putting the bracket into a vise. Bend it by using a crescent wrench or tapping it lightly with a hammer, into an “L” shape.

CAUTION: Do not drill any holes into the frame or the floorboard before checking for hydraulic lines, gas lines, and/or electrical wire that may need to be moved aside. Also, when attaching to the floorboard, it is important to check where the screws protrude through the floorboard. It may be necessary to trim or cover the top of the screws inside the vehicle. A sealer should be used around the screw to prevent the elements from entering the cab area.
