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 60 PSI and ensure there is at least 1/2”
clearance around each bellow, 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 60 PSI, check all connections for
leaks with a soapy water solution . See the
Checking for Leaks
section for tips 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 (800) 248-0892 .
Fastener test — Recheck all bolts for proper torque . Retorque after 100 miles .
Road test — The vehicle should be road tested after the preceding tests . Inflate the air
springs to 25 PSI (50 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 .
