Westar supplies 3 of the major components for your vehicles air suspension system.

Two air springs

Air Springs & Air Struts

Rubber Bellow with a crimped over a top plate and piston. This bellow bag expands and contracts based off the road conditions to dampen vibration. The air spring can be mounted separately, or as part of an air strut assembly.

Two solenoids

Solenoids/Pressure Regulator

A passageway for the air to pass from the compressor to the air spring. These act as doorways to regulate the amount of air going into and exhausting from the air bag. They can be mounted in one of 3 ways: on the air bag, on a separate block in the air line, or attached to the compressor assembly.

Compressor Dryer

Compressor & Filter Dryer

The compressor pumps the air into the system. It is controlled by the computer. The filter dryer removes the moisture and contaminates from the system. The airs passed from the pump through the filter dryer. Moisture is a major enemy of an air suspension system, and it is recommended that any time that a system is opened, the filter-dryer be either replaced or re-charged.

coil conversion

Other components that affect the way that you air suspension system works include: ride height sensors, relays, vibration insulators, and control modules. All of these components work in unison to give the vehicle a smooth and even ride.

Coil conversion kits

Westar offers a line of air spring to coil spring conversion kits. These kits offer the vehicle owner a way to convert their active air suspension system to a passive system at a significant cost savings of replacing the components.
