STEP 1 - PREPARE THE VEHICLE / UPPER BRACKET INSTALLATION

This installation assumes that there is no load in the bed of the truck. It is not necessary to remove the wheels for installation of this kit. Your vehicle is equipped with rubber jounce bumpers. The bumpers are attached to the frame directly above the axle. Remove these bumpers by unbolting from the frame.

This bumper will not be reused with this kit. Attach the upper bracket to the frame where the jounce bumper was removed using the 10mm X 50mm flat head bolt, placing the spacer between the upper bracket and the frame, as shown in Figure "A".

STEP 2 - PRE-ASSEMBLE THE KIT

Pre-assembly will begin with the left (driver's) side of the vehicle.

All pictures depict the installation on the left side of the vehicle unless noted otherwise. Attach the lower bracket to the air spring using a 3/4" flange hex bolt. Be sure that the lower bracket is attached to the air spring so that the bracket orientation is perpendicular to the leaf stack. See Figures "A" & "B".

STEP 3 - INSTALL THE ASSEMBLY TO THE VEHICLE

Place the air spring assembly on top of the jounce bumper pad on the axle housing, with the narrow end inserted in between the axle u-bolts. Insert the large stud on the air spring into the large hole in the upper bracket. See Figures "A" & "B". The alignment pin on the air spring will be inserted into one of the small holes in the upper bracket. Use which ever hole provides the best alignment. Secure the air spring to the upper bracket using the 5/8" jam nut. Install the air fitting into the large stud on the air spring and tighten NOTE USE TEFLON TAPE OR

PASTE BEFORE INSTALLING THE FITTING see Figure "A".

On the drivers side only, the parking brake line will need to be tie-wrapped to the upper bracket, see

Figure “A”

STEP 4 - ATTACHING ASSEMBLY TO THE AXLE

With the assembly attached to the frame rail, the next step is to attach the lower bracket to the jounce pad on the axle housing. Install the Bail Clamp under the leaf springs from the outside of the leaf pack, through the holes in the leg of the lower bracket. Secure (hand tight) using the 3/8”-16 flange nuts.

Insert the 6” carriage bolts through the lower bracket and capture them on the bottom side of the axle with the bracket strap. Secure (hand tight) using the 3/8”-16 flange nuts. Begin to tighten the nuts on the bail clamp first, to draw the bracket toward the leaf pack, making sure the bracket fits around the u-bolts. Alternate to the bracket strap until the bracket is secured. See Figures “A” & “B”.

Important: In order for the air spring to function properly, there must be a minimum of 1/2" of clearance around the air spring.

3 812-482-2932

STEP 4 - INSTALL THE PASSENGER'S SIDE ASSEMBLY

Follow steps 2 - 5 for assembly and installation of the passenger's side assembly.

This now completes the installation. Reattach the negative battery cable and remove the wheel chocks from the front wheels. Before proceeding, check once again to be sure you have proper clearance around the air springs. With a load on your vehicle and the air helper springs infl ated, you must have at least

1/2" clearance around the air springs. As a general rule, the air helper springs will support approximately

50 lbs. of load for each psi of infl ation pressure (per pair). For example, 50 psi of infl ation pressure will support a load of 2500 lbs. per pair of air helper springs. FOR BEST RIDE use only enough air pressure in the air helper springs to level the vehicle when viewed from the side (front to rear). This amount will vary depending on the load, location of load, condition of existing suspension and personal preference.

The LevelTow Compressor System is an automatic leveling system, once it is turned on(button illuminated blue) it will operate without any assistance.

7KH6PDUWVHQVRUVXSSOLHGZLWKWKHFRPSUHVVRUV\VWHPZLOOWHOOWKHV\VWHPWRLQÀDWHRUGHÀDWH to keep the vehicle level. It has a dwell range built in so that when the truck is going down the road hitting small defects the system will be idle. It isn’t until the sensor gets out of this dwell range for 18 seconds that the system will react.

The activation switch has to be illuminated blue for the system to work.

1. Before you install the compressor system, you will need to have the helper Airsprings installed. This will ensure that the LevelTow linkage does not get in the way of the

Airsprings.

3. Bolt the compressor to the bracket.

Position the compressor on the Bracket in the orientaion shown. Line up the holes in the (4) Mounting Bushings with the (4) holes in the Bracket. Install a #10 Flat Washer on each of the (4) #10-24 x 1 1/4” Pan Head

Screws. Insert a Screw/Washer in each of the 4 holes. Install a #10 Flat Washer on the threads sticking through the bottom of the bracket followed by a #10-24 Nylok Nut.

5. The Axle bracket can be mounted in any location on the axle tube to get the sensor linkage to line up. The Axle mount should be mounted on the axle so that the linkage will line up from the axle mount to the sensor.

Keep this in mind when establishing the sensor location.

6. The next step will be to mount the sensor. The

Smart Sensor needs to be centered in its travel at the trucks ride height to operate properly.

This can be done by cutting the linkage rod to

OHQJWK,WFDQEH¿QHWXQHGE\ORRVHQLQJWKH sensor mounting screws and twisting it in the mount and retightening the 4 screws. When the mounting and linkage is done it should look like the diagram seen here.

7. The sensor needs to be mounted on the frame rail with the wires pointing down. The arm will need to swing up opposite the direction of the wires as the suspension is being compressed.

Attach the sensor bracket to the frame with (4) self drilling screws supplied with the kit.

8. This diagram shows how the clamp sticks through the axle bracket. Loosen the clamp until it will open up and then slide it through the bracket. The whole assembly can then be put on the axle tube. Reinsert the end of the clamp back into the adjuster and tighten the clamp until the bracket is tight on the axle tube.

9. With the sensor and the axle bracket mounted, it is time to connect the 2 with the supplied linkage. The linkage is a universal length and will have to be cut to achieve the necessary length for your application. To do this it will be necessary to have the truck sitting at its factory ride height. With the truck at ride height center the sensor in its travel.

The rod can slide into each rubber rod end up to 1”.

10. The linkage rod has barbs on the outside of it to keep it in the end link. After you push

WKHHQGVLQWKH\DUHGLႈFXOWWRSXOOEDFNRXW

Push the linkage into the ends a little at a time until you get the desired length of the linkage assembly. If for some reason you must pull the rod out of the end, it is best done by twisting the end while pulling on it.

11. Mount the control panel in a convenient location. Install the Power Button and

Manual Control Rocker into the panel. The

Power Button gets installed into the round hole. The nut that is on the button is used to attach the button in the panel. The Rocker

Switch goes into the hole with the notch in it.

Align the tab on the switch with the slot and push the switch into the hole until it snaps in place. The rocker will only go into the hole one way. You can also custom mount the buttons if desired. They both use a 3/4” hole.

The hole for the manual switch will have to have a slot for the tab
