INSTALLATION INSTRUCTIONS

Congratulations - your new Air Helper Springs are

quality products capable of improving the handling and

comfort of your vehicle. As with all products, proper

installation is the key to obtaining all of the benefits your

kit is capable of delivering. Please take a few minutes to

read through the instructions to identify the components

and learn where and how they are used. It is a good idea

to start by comparing the parts in your kit with the parts

list below.

The heart of the kit is, of course, the air springs.

Remember that the air springs must flex and expand

during operation, so be sure that there is enough clearance

to do so without rubbing against any other part of the

vehicle.

Be sure to take all applicable safety precautions during

the installation of the kit. The instructions listed in this

brochure and the illustrations all show the left side of the

vehicle. To install the right side assembly simply follow the

same procedures.

This kit includes inflation valves and air lines for each

air spring. This will allow you to compensate for unbal-

anced loads. If you would rather have a single inflation

valve system to provide equal pressure to both air springs,

your dealer can supply the optional "T" fitting.

IMPORTANT!

For your safety and to prevent possible damage to

your vehicle, do not exceed the maximum load

recommended by the vehicle manufacturer (GVWR).

Although your Air Helper Springs are rated at a maximum

inflation pressure of 100 psi, this pressure may allow you

to carry too great a load on some vehicles. Check your

vehicle owner’s manual or manufacture plate on

driver side door for maximum loads listed for your

vehicle.

When inflating your Air Helper Springs, add air

pressure in small quantities, checking pressure fre-

quently during inflation. The air spring requires much

less air volume than a tire and, therefore, inflates much

quicker.

WARNING:

Do not inflate this assembly when it is

unrestricted. The assembly must be restricted by

the suspension or other adequate structure. Do

not inflate beyond 100 psi Improper use or over

inflation may cause property damage or severe

personal injury.

STEP 1 - PREPARE THE VEHICLE

First, measure the distance between the

tire and frame. If there is less than 6" of

clearance, do not proceed. There should be

no extra weight in the bed of the truck so that

the initial ride height of your air helper spring

kit will be correct. With the vehicle on a

solid, level surface chock the front wheels.

Raise the vehicle by the axle and remove the

rear wheels. After the removal of the wheels,

lower the vehicle so the axle rests on jack

stands rated for your vehicles weight. Remove

the negative battery cable.

THE“X”DIMENSION.

Throughout this manual we refer to an “X”

dimension.Thisistheinitial,un-inflatedover-

all height of the air spring. Both right and left

sides should be installed at the same height.

The “X” dimension on this air spring is 7"to

9". The air spring may require some stretching to achieve this dimension.

STEP 2 - PRE-ASSEMBLE THE KIT

Select one air helper spring from your kit. Install the upper bracket

by aligning the three holes on the air spring with the holes on the upper

bracket. Fasten the upper bracket to the air spring using the 3/8" x 3/4"

hex bolts as shown in Figure “A”. Install the air fitting as shown in

Figure “A”. Tighten the air fitting to make contact with the Teflon ring

and then tighten an additional 1/2 turn. No thread sealant is needed.

Insert the bail clamp into the lower bracket. Next, attach the lower

bracket and disk to the air spring using the 3/8"x 3/4" hex bolt (see

Figure “A”). Note: Finger tighten the bolt securing the lower bracket

and disk allowing the air spring to move freely. This will be tightened

after alignment in Step 6.

STEP 3 - ATTACH LOWER BRACKET TO LEAF SPRING

Place the assembly on the left side on top of the leaf spring stack

forward of the axle (see Figure “A” and “B”).Note the slight difference

in the lower bracket position on top of the leaf spring plate between Ford

and GM. Attach the lower bracket to the leaf stack using the bail clamp

(installed earlier), the bracket strap, and the flange lock nuts as shown in

Figure “A” and “B”. (Tighten to 15-20 ft. lbs.)

STEP 4- (GM TRUCKS)

CAUTION: The frame rails on some GM trucks have reinforcing ribs

used to strengthen to the frame rail. DO NOT drill through these ribs. If

the holes in the upper bracket align with these ribs, choose another hole

which is not on the rib and let the upper bracket rest against the rib. You

must use 2 holes on each side of the upper bracket. GM trucks with the

reinforcing ribs will require a flat washer between the upper bracket and

the frame to allow the upper bracket to rest squarely against the rib.

STEP 4– (FORD TRUCKS)

On FORD vehicles, unbolt the brake line bracket from the left frame rail.

Using the existing hardware, attach the brake line bracket onto the brake

line relocating bracket provided. This relocating bracket will be attached

to the inside of frame using the upper bracket mounting bolts. Relocation

is necessary to prevent the original brake line bolt from rubbing the air

spring. See Figures “A” & “C” for mounting.

ARK AND DRILL HOLES IN THE FRAME RAIL

Visually align the air spring so that it is vertically straight and the upper and lower brackets are parallel. Place the

upper bracket so the top of the bracket is parallel with the top of the frame rail. (Note: The upper bracket should not

extend beyond the top of the frame rail.) see Figure “A” and “B”. Check the “X” dimension on both sides of the air

spring, these dimensions should be the same (refer to Figure “B”).Before drilling the holes make sure all electrical,

brake and fuel lines are cleared from the path of the drill. In order to prevent any damage to these lines it is recommended

that a piece of wood be placed between the frame rail and the existing lines during drilling. With the air spring assembly in

place, mark the upper left hole with a center punch. Drill the hole using a 3/8" drill bit.

TEP

6 – (A

TTACHING THE UPPER BRACKET

Your kit includes 3/8" nut plates as well as 3/8" flange nuts that will be used to attach the upper bracket to the

frame. These nut plates allow entry into the frame in the areas where it would be difficult to use a wrench. Once the

hole has been drilled, attach the upper bracket using a 3/8" x 1 1/2" hex bolt and a nut plate (finger tight). (On Ford

vehicles use the brake line relocating bracket) This will allow you to adjust the location of the upper bracket. Once

the positioning of the upper bracket is parallel with the lower bracket and the “X” dimensions are the same, drill the

remaining holes in the frame rail using the upper bracket as a template. Use the 3/8" x 1 1/2" hex bolts and nut plate

on the front portion of the frame rail. Use the 3/8" x 1 1/2" hex bolts, large flat washers (inside of the frame) and the

flanged hex nuts to fasten the upper bracket to the frame rail. Figure “A”. Tighten the bracket attaching bolts to 28

– 32 ft. lbs. Once the upper bracket is secure, align the bottom of the air spring side to side to ensure that it

is vertical. Tighten the bolt securing the lower bracket to the air spring.

NSTALLATION OF THE RIGHT SIDE ASSEMBLY

Follow steps 1-5,

reversing all orientations,

for assembly and installation of the passenger’s side assembly. Both air helper

springs will install just to the front of the axle.

TEP

8 - I

NSTALL THE AIR LINE AND INFLATION VALVE

Uncoil the air tubing and cut it into two equal lengths. DO NOT FOLD OR KINK THE TUBING. Try to make the cut as square as

possible. Insert one end of the tubing into the elbow fitting installed in the top of the air helper spring. Push the tubing into the fitting as

far as possible.

Select a location on the vehicle for the air inflation valves. This can be on the bumper or the body of the vehicle, as long as it is protected

so the valves will not be damaged (see Figure “D”). Drill a 5/16" hole and install the air inflation valve using two 5/16" flat washers per

valve as supports (see Figure “E”). Route the tubing from the air helper spring to the inflation valve, avoiding direct heat from the engine,

exhaust pipe, and away from sharp edges. The air line tubing should not be bent or curved sharply as it may buckle with age. Secure

the tubing in place with the nylon ties provided. Push the end of the air line tubing into the inflation valve as illustrated (see Figure “E”).

TEP

9 - C

HECK THE AIR SYSTEM

Once the inflation valves are installed, inflate the air helper springs to 50 psi and check the fittings for air leaks with

an applied solution of soap and water. If a leak is detected, deflate the air spring by depressing the valve core. The tubing

can easily be removed from the fittings by pushing the collar on the fitting towards the body of the fitting while pulling

out the tube. Next, check the tubing connection to ensure that the air tubing is cut as square as possible and that it is

pushed completely into the fitting.

If a leak is detected where the air fitting screws into the air spring, gently tighten the air fitting into the spring

until the leak stops. Also, check the core of the inflation valve. This valve core can be tightened using the cap. Re-

inflate the air spring and check for leaks again if needed.

This now completes the installation. Install the wheels and torque the lug nuts to the manufactures specifications.

Raise the vehicle by the rear axle and remove the jack stands and lower the vehicle back onto the ground. Re-attach

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

inflated, you must have at least 1/2" clearance around the air springs. As a general rule, the Air Helper Springs

will support approximately 30 lbs. of load for each psi of inflation pressure (per pair). For example, 50 psi of inflation pressure

will support a load of approximately 1500 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

OTE

Too much air pressure in the air helper springs will result in a firmer ride, while too little air pressure will not allow the improvement

in ride and handling that is possible. TOPREVENT POSSIBLEDAMAGE MAINTAINA MINIMUMOF 10psi INTHE AIRHELPER

SPRINGS AT ALL TIMES. AFTER LOADING, YOU MAY USE UP TO 100 psi PER SIDE TO LEVEL THE TRUCK.

WHEN THE TRUCK IS LIFTED INTO THE AIR FOR SERVICE, DEFLATE BOTH AIR SPRINGS COMPLETELY.

AFTERWARDS, RE-INFLATE TO 10 psi PRIOR TO DRIVING.

OPERATING PRESSURE: MIN. - 10 PSI MAX (LOADED) - 100 PSI

Important:

In order for the air spring to function properly,

there must be a minimum of 1/2" of clearance

around the air spring.

The LevelTow Compressor System is an automatic leveling system, once it is turned on(button

illuminated blue) it will operate without any assistance.

The Smart sensor supplied with the compressor system will tell the system to inﬂ ate or deﬂ ate

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.

Activation Button

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 Air-

springs.

The  rst step to doing the install, with the

vehicle at ride height, measure the lip of

the fender to the ground at the center of the

wheel and write it down.

Measurement_________________

This measurement will be used as a refer-

ence once you have the compressor system

installed.

2. Unpack the wiring for the LevelTow sys-

tem and lay it out. This will give you an idea

to where you can mount the components

without having to modify the wiring harness.

NOTE:

There is a wiring diagram on Page 7 to assist

you in component location.

3. Bolt the compressor to the bracket. Po-

sition 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.

Tighten the hardware.

NOTE:

The diagram shows the position the com-

pressor goes onto the plate.

4. The compressor needs to be mounted

on the frame rail with the dryer up. Attach

the compressor bracket to the frame with (4)

3/8”-16 x 1” Thread Forming Bolts supplied in

the kit. Drill a 5/16” Hole for the bolts.

NOTE:

Before drilling any hole be sure to check and

see if there are any brake lines, fuel lines, or

wires on the other side of the surface you are

drilling.

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 sen-

sor location.

Page 3

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 length. It can be ne tuned by

loosening the 4 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.

NOTE:

The sensor can be mounted on the inside or

outside of the frame. Make sure the linkage

and arm can go through its entire travel without

hitting any obstructions

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.

Page 4

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

the ends in, they are diﬃ cult to pull back

out. 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
