Clearance test — Inflate the air springs to 75-90 PSI and make sure there is at least
1/2” clearance from anything that might rub against each sleeve . Be sure to check
the tire, brakes, frame, shock absorbers and brake cables .
Leak test before road test — Inflate the air springs to 75-90 PSI and check all
connections for leaks . All leaks must be eliminated before the vehicle is road tested .
Heat test — Be sure there is sufficient clearance from heat sources, at least 6” for
air springs and air lines . If a heat shield was included in the kit, install it . If there is no
heat shield, but one is required, call Air Lift customer service at
(800) 248-0892 .
Fastener test — Recheck all bolts for proper torque .
Road test — The vehicle should be road tested after the preceding tests . Inflate the
springs to recommended driving pressures . Drive the vehicle 10 miles and recheck
for clearance, loose fasteners and air leaks .
Operating instructions — If professionally installed, the installer should review the
operating instructions with the owner . Be sure to provide the owner with all of the
paperwork that came with the kit .
Overnight leak down test — Recheck air pressure after the vehicle has been used
for 24 hours . If the pressure has dropped more than 5 PSI, then there is a leak that
must be fixed . Either fix the leak yourself or return to the installer for service .
Air pressure requirements — It is important to understand the air pressure
requirements of the air spring system . Regardless of load, the air pressure should
always be adjusted to maintain adequate ride height at all times while driving .
Thirty-day or 500-mile test —Recheck the air spring system after 30 days or 500
miles, whichever comes first . If any part shows signs of rubbing or abrasion, the
source should be identified and moved, if possible . If it is not possible to relocate
the cause of the abrasion, the air spring may need to be remounted . If professionally
installed, the installer should be consulted . Check all fasteners for tightness .
