Q . The system won't maintain pressure overnight . What could be wrong?
One of the air lines may be improperly installed or a line may have a hole or crack.
Start by leak testing the air line connections. If no leaks are found, look for leaks in
the rest of the air lines. Follow the steps in "Fixing Leaks."
Q . One of the corners won't rise .
Look for a kink or fold in the air line going to that air spring. Replace any line that has
been kinked.
Q . Will installing air springs increase the weight ratings of a vehicle?
No. Adding air springs will not change the weight ratings (GAWR, GCWR and/
or GVWR) of a vehicle. Exceeding the GVWR is dangerous and voids the Air Lift
warranty.
Q . Is it necessary to keep air in the air springs at all times and how much pressure
will they need?
For LoadLifter 5000 Ultimate, the recommended minimum air pressure is 5 PSI, but it
can safely be run at zero air pressure.
Q . Is it necessary to add a compressor system to the air springs?
No. Air pressure can be adjusted with any type of compressor as long as it can
produce sufficient pressure to service the springs. Even a bicycle tire pump can be
used, but it’s a lot of work.
Q . How long should air springs last?
If the air springs are properly installed and maintained they can last indefinitely.
Q . Will raising the vehicle on a hoist for service work damage the air springs?
No. The vehicle can be lifted on a hoist for short-term service work such as tire
rotation or oil changes. However, if the vehicle will be on the hoist for a prolonged
period of time, support the axle with jack stands in order to take the tension off of the
air springs.
