CAUSE
Improperly installed air line, air line has
holes or cracks.
Fitting seal or air line is compromised.
Look for a kink or fold in the air line.
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.
will they need?
For LoadLifter 5000 standard, Ultimate and Ultimate Plus, the recommended
minimum air pressure is 5 PSI, but it can safely be run at zero air pressure unladen
(no load).
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.
If the air springs are properly installed and maintained they can last indefinitely.
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.

Trim hose or re-seal fitting. Ensure lines are
cut straight.
Replace any air line that has been kinked.
