The Loadshare system comes complete with air bellows, mounting hardware, brackets, pressure control system and installation instructions. The air bellows and brackets are designed to fit in the open space between the axle centerline, spring package and the bottom of the vehicle frame.
Regulated air pressure is supplied to the air bellows. This controlled or regulated air pressure will fill each bellow extending it in length. Therefore, as the air spring is located between the axle and the vehicle frame, the truck suspension will be leveled to the proper height. If the vehicle was loaded with payload, the air bellows would transfer part of the weight directly to the axle and through the tires to the pavement. Therefore, this will help to reduce the load transferred through the leaf springs and shackles, reducing the amount of wear on these particular components.
The air pressure is controlled by means of a pressure regulator which can be adjusted manually by the driver. Pressurized air is supplied to one side of the regulator and the controlled air is released into the system. This can be accomplished by use of a knob or lever on the regulator unit. The required air pressure can be read on a pressure gauge located in the system. The required air pressure is supplied by the vehicle's standard air compressor system as outlined on the schematic. This control unit is usually installed in the vehicle dashboard.
