AFTER COMPLETING THE INSTALLATION

PLEASE REMEMBER:

Install wheels and torque fasteners to manufacturer’s specifications.

Re-torque all fasteners after first 500 miles of driving.

For safe and proper operation, never operate the vehicle under 
minimum of 10 psi or over maximum of 100 psi in air springs. Staying 
within pressure limit will ensure maximum air spring life. Failure in 
doing so may result in a void warranty (see 

Note

 below).

NOTE: Do not exceed maximum vehicle payload. Failure to do so 
my result in failure of the air suspension kit and/or damage to your 
vehicle. 

Thank you again, and congratulations on the installation of the air suspension kit. 

OPTIONAL ACCESSORIES

Optional dual needle air gauges are available to monitor pressure in each spring from vehicle cab, as well as a full line of air 
compressors, air tanks, and solenoids built to work with and control your air spring system.

OPERATING YOUR VEHICLE WITH AIR SUSPENSION

Air springs have minimum and maximum pressure requirements. Never operate your vehicle with less than 10 psi in air spring and 
never infl ate air springs over 100 psi. Damage to air springs will result.

Check air pressure in air springs daily for fi rst couple of days to ensure a leak has not developed. Air springs are designed to 
maintain the vehicles stock ride height with a load. Do not use the air springs as a means to lift vehicle with no load. This will result 
in a harsh ride.

SERVICING YOUR VEHICLE WITH AIR SUSPENSION

When lifting the vehicle with a fl oor jack or hoist on the frame, never allow the air spring to limit the travel of the axle. Try to always 
jack the vehicle on the axle. Suspending the axle with the air spring limiting the axle travel will damage the air spring and void the 
air spring warranty.

WARRANTY

To be eligible for warranty, the owner must submit their warranty card or register online within 30 days of the purchase date.

NOTE: The owner’s warranty will be void if air springs are run with less than the minimum of 10 psi.
