WARNING:  
Do not inflate this assembly when it is  
unrestricted. The assembly must be re-  
stricted by the suspension or other adequate  
structure. Do not inflate beyond 100 P.S.I.  
Improper use or over inflation may cause  
property damage or severe personal injury.  
INSTALLATION INSTRUCTIONS  
Congratulations - your new Ride-Rite 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.  
Your kit includes separate inflation valves and air  
lines for each air helper spring. This will allow you to  
level your vehicle from side to side as well as from front  
to back. If you would rather have a single valve inflation  
system, your dealer can supply the required "T" fitting.  
IMPORTANT!  
For your safety and to prevent possible damage to  
your vehicle, do not exceed the maximum load recom-  
mended by the vehicle manufacturer (GVWR). Al-  
though your Ride-Rite Air Helper Springs are rated at  
The heart of the Ride-Rite kit is, of course, the air  
helper springs. Remember that the air helper 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.  
a
maximum inflation pressure of 100 P.S.I., this  
pressure may allow you to carry too great a load on  
some vehicles. Check your vehicle owner’s manual for  
maximum loads listed for your 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, or  
driver’s side of the vehicle. To install the right side  
assembly simply follow the same procedures.  
When inflating your Ride-Rite Air Helper Springs,  
add air pressure in small quantities, checking pressure  
frequently during inflation. The air spring requires  
much less air volume than a tire and, therefore, inflates  
much quicker.

STEP 1 - PREPARE THE VEHICLE  
Make sure that the vehicle is on a solid level surface. Take necessary  
safety precautions such as using wheel chocks when working under your  
vehicle. This vehicle does not have to be jacked up to install the kit.  
Remove the positive battery cable. Remove the rubber jounce bumper  
under the frame rail, see Figure "B".

STEP 2 - PREASSEMBLE THE RIDE-RITE KIT  
Select one air helper spring from your kit and install the air fitting  
as shown in Figure "A". Tighten the air fitting securely to engage the  
orange thread sealant. Insert the 1-1/2" carriage bolt into the square  
hole on the left upper bracket marked "L". Align the studs on the air  
spring with the holes on the upper bracket making sure the air fitting  
aligns with the circular cut out, see Figure "A". Use the 3/8"-16 flanged  
lock nuts to secure the upper bracket to the air spring. Position the lower  
bracketasshowninFigure"A". Fastenthelowerbrackettotheairhelper  
spring using a 3/8"-16 x 3/4" flanged hex bolt (finger tight).

STEP 3 - ATTACHMENT TO THE FRAME  
Place the round sleeve over the 1-1/2" carriage bolt installed earlier (see  
Figure "A"). Position the assembly on the axle under the frame rail in the  
location shown in Figure "A". The tab on the upper bracket will fit into  
the jounce bumper bracket opening. Note that the carriage bolt will also fit  
into the existing slot on the jounce bumper bracket as shown in Figure "A".  
Using the 3/8" special flat washer and 3/8"-16 flanged hex nut attach the  
upper bracket to the jounce bumper bracket, see Figure "A". Hint: Use a  
boxed ratchet style wrench to tighten the upper bracket to the jounce  
bumper bracket.

STEP 4 - LOWER BRACKET ATTACHMENT  
Positioning of the lower bracket is determined by the air spring.  
Visually align the air spring so that it is as vertical as possible. Once the  
air spring is correctly aligned install the 3/8"-16 x 3" carriage bolts in the  
squareholesofthelowerbracketasshowninFigure"A". Thelowerbracket  
is then secured by two bracket straps which are placed under the axle and  
fastened with 3/8"-16 flanged lock nuts, see Figure "A". After the lower  
bracket is fastened to the axle tighten the air spring to the lower bracket  
making sure the air spring remains in a vertical position.

STEP 5 - INSTALLATION TO THE PASSENGER'S SIDE ASSEMBLY  
Reverse any orientations when assembling and installing the  
right, or passenger, side of the vehicle. Use the upper bracket stamped  
"R", follow steps 2-4 for assembly and installation. Note: The use of  
a heat shield is required on the passenger's side of the vehicle refer  
to Figure "C". The heat shield will mount between the upper bracket and  
theairhelperspring. Angletheheatshieldsoitisplacedhalfwaybetween  
the air helper spring and the closest point on the exhaust. Be sure that the  
heat shield will not contact any other component as the suspension  
compresses. (i.e. brake lines, shock absorbers, lower bracket assembly)

STEP 6 - INSTALL THE AIR LINE AND THE INFLATION VALVE  
FLAT WASHER  
Uncoil the air line 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 straight 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 in Figure "E".  
STEP 7 - CHECK THE AIR SYSTEM  
Once the inflation valves are installed inflate the air helper springs to 70 P.S.I. 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 fitting screws into the spring, remove the tubing (see trouble shooting section of the operating instruction  
manual for removal procedure),then screw the brass fitting into the air spring one additional turn or until the leak stops.  
Reinstall the tubing and reinflate the air springs and check for leaks as noted above. Further information on trouble-  
shooting can be found in the General Operation Instruction book included with this kit.  
This now completes the installation. Re-attach the postive 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 Ride-Rite Air Helper Springs will support approximately 32 lbs. of load for each P.S.I. of inflation  
pressure (per pair). For example, 50 P.S.I. of inflation pressure will support a load of 1600 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 P.S.I. IN THE RIDE-RITE AIR  
HELPER SPRINGS AT ALL TIMES.  
Enclosed with this kit are Ride-Rite Operating Instructions. Please read them for proper and safe operation.  
NOTE:  
Once the air helper springs are installed, it is recommended that the vehicle not be lifted by the frame, as over-  
extension may occur, resulting in damage to the air helper springs. However, should it become necessary to raise the  
vehicle by the frame, deflate both air helper springs completely.
