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
— Regardless of load, the air pressure should always be
adjusted to maintain ride height at all times.
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 30 PSI and ensure there is at least 1/2”
clearance around each air spring, away from anything that might rub against them.
Be sure to check the tire, brake drum, frame, shock absorbers and brake cables.
Leak test before road test
— Inflate the air springs to 30 PSI, check all connections
for leaks with a soapy water solution. See Checking for Leaks on how to spot leaks.
All leaks must be eliminated before the vehicle is road tested.
Heat test
— Be sure there is sufficient clearance from any 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. Re-torque after 100 miles.
Road test
— The vehicle should be road tested after the preceding tests. Inflate the
air springs to 25 PSI (30 PSI if the vehicle is loaded). Drive the vehicle 10 miles and
recheck for clearance, loose fasteners and air leaks.
Operating instructions
— If professionally installed, the installer should review the
Product Use, Maintenance and Servicing section with the owner. Be sure to provide
the owner with all of the paperwork which came with the kit.
