CAUTION

PRE-INSTALLATION CHECKLIST
Check the vehicle wheel alignment prior to installation to insure no precondition already exists; record the information for verification. Remove the attached body, if applicable. Remember to disconnect all electrical connections to the body, and fuel filler tube, before removing the body. The installation can also be completed using a lift to raise the vehicle. If using a lift, chassis body removal may not be necessary but removal of rear wheels will aid in installation. If not using a lift, block the front wheels and apply the emergency brake so the vehicle cannot roll. Jack up the rear frame of the truck in order to unload the rear leaf springs (or use an overhead hoist). Do not lift the wheels off the ground (if not using a lift to install the suspension). Do not jack on the axle itself. Install the suspension in the listed sequence. Install one side of the suspension at a time. First, install the driver side completely, then install the passenger side. Removal of the rear wheels may aid in installation, but it is not necessary. Measure & record the wheelbase and centering dims before beginning installation.

10. ELECTRICAL SYSTEM

1. Refer to AIR CONTROL SYSTEM INSTALLATION INSTRUCTIONS for further details on electrical system installation and parts list.
CAUTION! All wiring should be routed and secured neatly to avoid any functional or visual issues. Under hood and under-body wire routings should be clear of sharp edges (3/4 inches minimum) and direct sources of heat (4 inches minimum). Wiring located in the passenger compartment should be routed away from high temperature areas over the muffler. Wiring should not be routed through wheel well areas where it may be damaged by tire or road debris, and it should not be routed over the exhaust system. Wiring should not contact the brake lines or fuel lines.
11. FINAL INSPECTION CHECKLIST
Air System Start Up and Check Remove all jacks and air system up by either using the fill valve on the air tank or by starting the vehicle and switching the compressor switch to ON. Note: the maximum allowable pressure in the air tank is 150 psi. It is recommended to fill the air tank using the supplied schraeder valve so that the compressors are not taxed too much by running for a long period of time. Height Control Valve Operation Check. With one end of the valve linkage disconnected rotate the valve arm down 45, air should exhaust from the air springs. Rotating the valve arm up 45 should cause the valve to fill the air springs. Measure & Record the Design Height of the air springs. Measure design height of the AIR SPRING at the middle of the air spring and compare with the value called out in Fig. 11-1. To adjust the design height complete the following steps (see Figures 11-2) Disconnect one end of the valve linkage and adjust accordingly. Turn the plastic ball end joint to change the length of the linkage (increasing the length will increase the Design Height, and vise-versa). Tighten the lock nuts on the valve linkage when complete. Once the design height is set, reconnect the linkages. Jostle the suspension up and down and then allow it to come back to design height. Recheck the initial measurement and adjust if needed. Note: This procedure to set design height can be done when empty or under light load Bushing Bolts Final Torque With the suspension at design height torque all bushing fasteners. This will include all fasteners for the Control Arm, Sway Arm and LCR bushings. (See Table 11-1 for appropriate Torque)

7.40 INCHES AIR SPRING DESIGN HEIGHT

FIG. 11-1

Move the suspension throughout its entire range of motion, by inflating and deflating the air springs to achieve full travel. Check for any interferences with the lateral control rod, axle, shocks, exhaust, frame, brake lines (especially on the driver side), fuel lines, etc. Reconnect the valve linkage to the lever. Note: if contacting the brake lines, hand caulk the line to make clearance at least 1/4. Recheck all fasteners for specified torque. Double check all electrical connections and wire routings. IMPORTANT! Check all fittings and airlines for air leaks. Reinstall the chassis body (if applicable). Measure and record wheelbase centering dims on following page. and

12. OPERATION GUIDELINES

After all final checks are complete, it is recommended to complete a full four- wheel alignment and drive line angle check. The pages following the installation instructions describe the proper method for checking driveline angles. Note: improper driveline angles may have a detrimental effect on ride, u-joints, and transmission. If any driveline vibration (or out of spec. angle measurement) occurs, use factory axle seat shims to modify driveline angle. Kneeling Operation: Moving the switch ON to Dump will exhaust all air from the air springs and lower the rear of the vehicle approximately 3-4 inches. Air springs will inflate when the switch is returned to the OFF position. WARNING: Do not drive the vehicle while the Dump Switch is on and the air springs are deflated. IMPORTANT! During servicing check tightness of all fasteners and for any air system leaks. IMPORTANT! Immediate corrective action should be taken if malfunctions occur. Air Spring Design Height Setting Procedure for Systems with Dual Height Control Valves 1. Deflate the passenger side air bag by disconnecting the linkage from the arm. 2. With the driver side linkage connected, measure the design height and adjust accordingly by the methods mentioned above, 3. Once the design height is set for the driver side, repeat the same steps for the passenger side, including deflating the driver side air bag. 4. Once the design height is set, reconnect the linkages. 5. Jostle the suspension up and down and then allow it to come back to design height. Recheck the initial measurement and adjust if needed. Note: this procedure to set design height can be done when empty or under light load. 15

13. SERVICE & MAINTENANCE
The UltraRide suspension needs no lubrication and little maintenance. The following components should be checked at the time the truck is being serviced. However, immediate corrective action should be taken if a serious malfunction occurs. See Exploded Assembly on following page for details. CAUTION! If maintenance or service is to be done on the air system, be sure to drain all air from system. Serious injury could occur if components are removed while system is full of air. Note: It is important to release any moisture contained within the air reservoir on a daily basis. See Air Kit Manual for details. Not releasing the moisture on a regular basis will cause the drain valve to not operate properly, and may cause the valve to malfunction. Excess moisture in the system can also cause premature failure of other components including the tank itself. AIR SPRING SERVICE The air spring can be serviced without removing the axle brackets from the axle. Simply unbolt the adapter plate from the Upper Axle Mount, and also detach the air spring bead plate from the Upper Air Spring Mount (See figure 12-1).

FORD F350 OWNERS GUIDELINES
The UltraRide suspension needs no lubrication and little maintenance. corrective action should be taken if a serious malfunction occurs. However, immediate CAUTION! If maintenance or service is to be done on the air system, be sure to drain all air from the system. Serious injury could occur if components are removed while system is full of air. PRODUCT OWNER RESPONSIBILITIES Owner is solely responsible for pre-operation inspection, periodic inspections, maintenance, and use of the product as specified in the particular LINK MFG. instructions available by product model, except as provided in this warranty, and for maintenance of other vehicle components. Of particular importance is the re-torque of fasteners including axle u-bolts, torque rod bolts and track rod bolts. This re-torque must be performed within 90 days of the suspension being put in service. Owner is responsible for down time expenses, cargo damage, and all business costs and losses resulting from a warrantable failure. The UltraRide Chassis Air Suspension is fully automatic in controlling the height of the chassis. No manual intervention to control air pressure or ride height is needed during the course of operation. The Compressor Switch must be on for the compressors to operate. During difficult starting circumstances, (i.e. extremely cold weather) it is recommended to turn the compressor switch off until the vehicle is running, so it will not draw current from the battery. The compressors are controlled by the pressure switch located in the Air Control Box. This switch automatically turns the compressors on when the tank pressure falls below 100 psi, and turns them off at 120 psi. The Low Pressure Warning Light indicates a severe drop in tank pressure (below 60 psi). Immediate corrective action should be taken to determine the cause of air loss. Compressor switch should be turned off if Low Pressure Warning Light is on, and remains on even after the compressors have run for a normal period of time. NOTE: The Low Pressure Warning Light could come on briefly when the Dump feature is being used. It is important to release any moisture contained within the air tank on a daily basis. This is done by pulling on the attached release cable for approximately 5 seconds. See Air Control Kit Owners Manual for location of this cable. Not releasing the moisture on a regular basis will cause the drain valve to not operate properly. CHECK AT EVERY VEHICLE SERVICE INTERVAL: Check Design Height. Check for air leaks around fittings. CHECK AFTER THE FIRST 1000 MILES: Recheck & tighten any loose fasteners. Check for any loose or worn components.
