- Some vehicles are equipped with a rear wheel brake proportioning valve. Check with the manufacturer before installing the air spring kit, as it may affect braking performance.
- It is recommended to use a good quality anti-seize on all fasteners. This will reduce the chance of corrosion on the fasteners and will help facilitate removal, if required at a later date.
PLEASE NOTE:
This kit contains push-to-connect fittings; using scissors or wire cutters to cut the nylon airline will distort the line and cause the connection to leak. THE AIRLINE MUST BE CUT OFF SQUARELY WITH THE NYLON HOSE CUTTER PROVIDED IN THIS KIT OR A SHARP UTILITY KNIFE.
-
MEASURE STOCK RIDE HEIGHT
Park the vehicle on a level surface. Using a measuring tape, measure the distance between the center of the wheel hub and the bottom of the fender well (as shown in Figure 1) this will give you your ride height. Note the ride height for all four corners. -
REMOVE REAR WHEELS
Place wheel chocks in front of and behind both front wheels. Raise the rear of the truck high enough to remove both wheels and attain a comfortable working height. Place two jack stands under rear axle (shown in Figure 2). Lower the vehicle until the axle is supported by the jack stands. Remove rear wheels. -
REMOVE THE JOUNCE BUMPER
The jounce bumper assembly ( shown in Figure 3) consists of a cup and a bumper. It is bolted to the frame with a single bolt running through the center of the jounce bumper. Remove the bolt holding the jounce bumper to the frame with a 13 mm socket. A socket extension may be required to reach the bolt. -
ATTACH THE UPPER BRACKET TO THE FRAME
Assemble the upper bracket (B) as shown in Figure 4A. Place the upper frame bracket on the frame rail and position by inserting the M10 x 1.5 x 45 mm bolt (I) through the locating hole in the bottom of the bracket into the jounce bumper bolt hole. Torque the M10 bolt to 30 ft-lbs (41 N-m). Insert a 3/8” – 16 x 1.25 carriage bolt (J) through a carriage bolt locking bracket (Q). Insert the bolt and bracket combination through the oval hole on the rear side of the frame and align with the mounting holes. Fishing wire may be needed to pull the bolt and bracket combination through the frame. Secure the bracket to the frame using two 3/8” – 16 nylock nuts (L) and two 3/8” flat washers (O). Torque the nylock nuts to 20 ft-lbs (27 N-m). A correctly attached bracket should appear as shown in Figure 4B. Repeat on opposite side
-
ASSEMBLE THE AIR SPRINGS AND BRACKETS
Set the roll plate (H) over the over the bottom of the air spring (A).
Set the lower spring bracket (E) onto the air spring ensuring that the holes in the air spring, roll plate and lower bracket all line up. Fasten the assembly together using two 3/8”– 24 x 7/8” hex cap bolt (N), two 3/8” lock washers (P) and two 3/8” flat washers (O). Torque the mounting hardware to 20 ft-lbs (27 N-m). Turn the assembly over and set the roll plate (H) over the top of the air spring. Fasten the swivel fitting (R) into the top of the air spring. It is recommended to use Teflon tape or some form of thread sealant to prevent air leaks. Finger tighten the swivel fitting and turn an extra 1.5turns to tighten Set the upper airbag bracket (B) onto the air spring ensuring that the holes in the air spring, roll plate and bracket all line up. Fasten the assembly together using two 3/8”– 24 x 7/8” hex cap bolt (N), two 3/8” lock washers (P) and two 3/8” flat washers (O). Torque the mounting hardware to 20 ft-lbs (27 N-m). Repeat for the other air spring. -
INSTALL THE AIR SPRING ASSEMBLIES
Note: It may be necessary to raise the frame of the truck a few inches to allow more clearance to install the air spring assemblies. Place the air spring assembly onto the truck with the lower bracket sitting on the leaf spring and the upper airbag bracket between the extended arms of the upper frame bracket (shown in Figure 6). Attach the upper airbag bracket to the upper frame bracket using four 3/8” – 16 hex bolts (M), four 3/8” flat washers (O) and four 3/8” – 16 nylock nuts (L). Torque the mounting hardware to 20 ft- lbs (27 N-m). Repeat for the opposite side
-
ATTACH LOWER BRACKETS TO LEAF SPRINGS
Insert four 3/8” – 16 x 3.50” carriage bolts (K) into the mounting holes in the lower bracket (as shown in Figure 7). Clamp the lower bracket to the leaf spring using the leaf spring clamp bar (G). Secure using four 3/8” – 16 nylon locknuts (L) and four 3/8” flat washers (O). Torque the locknuts to 20 ft-lbs (27 N-m). Repeat on opposite side -
INSTALL AIR LINE
PLEASE NOTE: This kit contains push-to-connect fittings; using scissors or wire cutters to cut the nylon airline will distort the line and cause the connection to leak. THE AIRLINE MUST BE CUT OFF SQUARELY WITH THE NYLON HOSE CUTTER PROVIDED IN THIS KIT OR A SHARP UTILITY KNIFE
Provided in air spring kit are two fill valves. The most common place to install is in place of license plate fasteners. Alternatively, two 5/16” holes can be drilled in a convenient location. Cut air line assembly into two equal lengths with hose cutter. Install one air line, route the nylon air line to an air spring fitting and cut the hose. Moisten the end of the air line prior to inserting it into the fitting and push it in until it stops. Repeat with the other fill valve. Secure airlines using the tie-straps, away from moving items and heat sources. Place a 5 ⁄16” nut on the air valve. Leave enough of the inflation valve in front of the nut to extend through the hole, install a flat washer, and 5 ⁄16” nut and cap (reference Figure 8 for assembly). There should be enough valve exposed after installation—approximately ½”—to easily apply a pressure gauge or an air chuck. If an in-cab inflation kit is being installed, follow the instructions provided with that kit now. -
CHECK SYSTEM FOR LEAKS
Inflate both air springs to 90 psi and then use a mixture of dish soap and water on all air line connections to detect any air leaks. Large, expanding bubbles indicate a leak (as shown in Figure 9). Repair as necessary and retest. Inflate air springs to a predetermined value and on following day recheck pressure. If one or both of air springs have lost pressure, an air leak is present. Leak must be repaired, and then retested until no leaks exist. -
AFTER COMPLETING THE INSTALLATION
PLEASE REMEMBER:
Install wheels and torque fasteners to manufacturer’s specifications. Re- torque all fasteners after first 500 miles of driving. For safe and proper operation, never operate the vehicle under minimum of 10 psi or over maximum of 100 psi in air springs. Staying within pressure limit will ensure maximum air spring life. Failure in doing so may result in a void warranty (see Note below).
NOTE: Do not exceed maximum vehicle payload. Failure to do so my result in failure of the air suspension kit and/or damage to your vehicle.
Thank you again, and congratulations on the installation of the air suspension kit.
OPTIONAL ACCESSORIES
Optional dual needle air gauges are available to monitor pressure in each spring from vehicle cab, as well as a full line of air compressors, air tanks, and solenoids built to work with and control your air spring system.
OPERATING YOUR VEHICLE WITH AIR SUSPENSION
Air springs have minimum and maximum pressure requirements. Never operate your
vehicle with less than 10 psi in air spring and never infl ate air springs
over 100 psi. Damage to air springs will result.
Check air pressure in air springs daily for fi rst couple of days to ensure a
leak has not developed. Air springs are designed to maintain the vehicles
stock ride height with a load. Do not use the air springs as a means to lift
vehicle with no load. This will result in a harsh ride.
SERVICING YOUR VEHICLE WITH AIR SUSPENSION
When lifting the vehicle with a fl oor jack or hoist on the frame, never allow the air spring to limit the travel of the axle. Try to always jack the vehicle on the axle. Suspending the axle with the air spring limiting the axle travel will damage the air spring and void the air spring warranty.
WARRANTY
The owner’s warranty will be void if air springs are run with less than the minimum of 10 psi. See additional warranty for details.
