INSTALLATION CHECKLIST

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.
POST-INSTALLATION CHECKLIST

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.
