air-Ride Suspension
The air-ride suspension system consists of frame
brackets, suspension links, axle connections, air
springs, shock absorbers, and a height control
valve.
The air-ride suspension is designed to provide
a level, cushioned ride throughout all legal load
ranges. The height control valve maintains the
suspension ride height by regulating air to the air
springs. Trailers are equipped with a spring brake
priority emergency valve. This dedicates air to
releasing the spring brakes first, before charging
the reservoir and supplying air to the suspension
system. To ensure the reservoir and suspension
are properly charged, do not operate the trailer until
the tractor air gauges indicate the system is fully
charged and stabilized.
In compliance with DOT requirements, the
suspension system should be inspected before and
after operation:
• Check each air spring to verify sufficient inflation.
Fill each spring to equal firmness and verify there
is no physical damage present.
• Check all shock absorbers for leaking or damage.
• Check the height control valve to ensure the
linkage is properly connected.
Additional information related to maintenance and
operation of a specific suspension system can be
