  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 ½” 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 page 12 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 . Axle clamp bar carriage bolt lock 
nuts should be torqued to 16 ft/lbs . Re-torque 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 on page 14 with the owner . Be sure to provide 
the owner with all of the paperwork which came with the kit .
