HP10121 AMP AIR SUSPENSION KIT
L5934
L5934.REV10_16.07.2018
Thank you and congratulations on the purchase of an AMP air suspension kit.
IMPORTANT:
The air suspension kit will not increase the GVWR (gross vehicle weight rating), as this is determined by the
axle rating. Do not exceed the maximum capacity listed by the vehicle manufacturer.
Before starting, ensure the application information is correct for the make, model and year of the vehicle you
are installing it on. Please read the entire installation manual prior to starting the installation to ensure you can
complete it once started.
Pacbrake recommends using a good quality anti-seize on all fasteners, this will reduce the chances of corrosion
of the fasteners, and help facilitate removal if required at a later date.
