bracket to the leaf stack. See Figures "A" and "B". Fasten using the 3/8"-16 flange lock nuts. Adjust the air
spring to achieve vertical alignment. Tighten the 3/8"-16 flange bolt that holds the air spring to the lower bracket
using an open end wrench.
STEP 5- INSTALLATION OF THE PASSENGER'S SIDE ASSEMBLY
Follow steps 1-4 for assembly and installation of the passenger's side.
STEP 6- INSTALL 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 refer to Figure "A".
Select a location on the vehicle for the air inflation valves. The location can be on the bumper or the body of the
vehicle, as long as it is in a protected location so the valve will not be damaged, but maintain accessibility for the
air chuck (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"). Run the tubing from the air helper spring to the inflation valve, routing
it to avoid direct heat from the engine, exhaust pipe, and away from sharp edges. Thermal sleeves have been
provided for these conditions. If a thermal sleeve is required simply slide the sleeve over the air line tubing
to the location requiring protection. The air line tubing should not be bent or curved sharply as it may buckle.
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").
STEP 7 - CHECK THE AIR SYSTEM
Once the inflation valves are installed inflate the air helper springs to 70 psi. and check the fittings for air leaks
with an applied solution of soap and water. If a leak is detected at a tubing connection then check to make sure that
the tube is cut as square as possible and that it is pushed completely into the fitting. The tubing can easily be removed
from the fittings by pushing the collar towards the body of the fitting and then pulling out the tube. If a leak is detected
where the brass elbow fitting screws into the spring, remove the tubing (see trouble shooting section of the operating
instruction manual for removal procedure),then screw the elbow into the spring one additional turn or until the leak
stops. Reinstall the tubing and reinflate the air springs and check for leaks as noted above.
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 40 lbs. of load for each psi. of inflation pressure (per pair). For example, 50 psi. of inflation
pressure will support a load of 2000 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.
NOTE:
Too much air pressure in the air helper springs will result in a firmer ride, while too little air pressure will allow
the air helper spring to bottom out over rough conditions. Too little air pressure will also not provide the
improvement in handling that is possible. TO PREVENT POSSIBLE DAMAGE MAINTAIN A MINIMUM OF
20 psi. IN THE AIR HELPER SPRINGS AT ALL TIMES.
MIN PRESSURE 20 PSI
MAX PRESSURE (LOADED) 100 PSI
