Installation Instructions
Figure 4
10. Attach the beam mounted lift bracket under the trailing
arm with 1/2" bolts, washers, and nuts.
11. Install the PosiLift air spring to both the hanger mounted
and beam mounted lift brackets
(Figure 4)
.
NOTE:
Air spring should be mounted using inboard holes
(Figure 5)
.
12. Insert the equalizing beam and new pivot connection
hardware.
13. Lower axle to ride height and re-support with jack stands.
Shear Bolt - Tighten connection until spline shears
IMPORTANT:
Make sure the lift bracket is properly
positioned to the suspension frame
bracket and the tie plate is attached
before tightening the pivot connections
(Figure 6)
.
Failure to properly position the lift
bracket could result in component
interference which, if not avoided, could
result in component or property damage.
NOTE:
Make sure the SwingAlign™ washers and
components are in place prior to tightening
the connection.
14. Connect the PosiLift air spring to the air control system.
For plumbing instructions and diagram for manual lift,
refer to Section 5 and solenoid styles refer to Section 6.
15. Reinstall the height control valve linkage to the lower
height control valve tab and properly torque the fasteners.
16. Lower the axle until the tires are back on the ground
and remove the jack stand supporting the axle only.
17. Increase the suspension air system to proper operating
pressure and check for leaks by applying a soapy water
solution and checking for bubbles at all connections and
fittings. If leaks are found, service as necessary.
IMPORTANT:
It is the responsibility of the air system
installer to secure all air lines and check
for air leaks. If air leaks are detected,
repair as required.
Failure to eliminate air leaks could
compromise the suspension performance
which, if not avoided, could result in
component or property damage.
