With the air helper springs installed on your vehicle and the vehicle sitting on a level surface, visually verify that

the vehicle is in a level state. If the vehicle is not level (front-to-back or from side-to-side) it can be brought to a

level position by inflating the air springs. Each air spring has a separate inflation valve. To level the vehicle from

front-to-back, add air pressure to both air springs in equal amounts. To level the vehicle from side-to-side, add

more air pressure to the air spring on the lower side of the vehicle. When inflating the air springs, add air pressure

in small quantities, checking the pressure frequently. The air spring requires much less air volume than a tire, and

therefore, will inflate and deflate quickly.



Check the level of your vehicle visually. If it is not level, either from front to back or from side to side, level it by

inflating your air springs. (If your vehicle is equipped with a cab control unit or automatic control system refer to

the directions for that device.) There is one inflation valve for each air spring. To level from front to back, add air

pressure to both air springs equally. For side to side, add air pressure to the air springs on the side of the vehicle

that is low. When adding air pressure to the air springs, remember that they have a much smaller volume of air that

a tire so they will inflate much quicker. Add air pressure in short bursts until the vehicle is level. (NEVER EXCEED



It is considered normal for air helper springs to lose some air pressure over time. Normal pressure loss should not

exceed 3 – 4 psi per week when the air springs are inflated to 50 psi. If the pressure loss is greater than 3 – 4 psi

per week, there may be a leak in the system. Each time you check the pressure in the air springs, you will lose 1 – 3

psi. The air pressure should be checked at regular intervals.

It is recommended that the air pressure be checked according to the following guidelines:

At least monthly intervals during the continuous operation of the vehicle (see above)
When the vehicle is removed from long-term storage
If the air springs are used to assist in leveling an RV or camper on uneven ground, ensure that the vehicle is

returned to a level ride height before departing.

The brackets used to secure the air helper spring to the vehicle should be inspected periodically for damage and

for loose fasteners. Ensure that the air line tubing is clear of any sharp edges and routed away from the exhaust

system. The brackets and air line tubing should be inspected every 6 months. Ensure that the threaded fasteners

are torqued to the specifications listed on Page 3.
Accumulated sand, gravel, or other road debris on the air springs or brackets should be rinsed away with a garden

hose each time the vehicle is washed.

If it is necessary to lift the vehicle by the frame, first release the air pressure from the air springs. This will allow the air

springs to extend to their maximum length without being damaged. The uninflated air springs are capable of supporting

the weight of the axle when the vehicle is lifted by the frame. After servicing of the vehicle is complete, lower the vehicle

to the ground and reinflate the air helper springs to the desired pressure. NOTE: On Sport-Rite kits the air helper springs

must be aired up to 50 psi and then release the air until the air helper springs are to the desired pressure.
