9. Quick-change Ride Height
The SL2065 suspension series is equipped with the W&C quick-change ride height system. The lower
bag plate spacers are easily removed to change to a different height spacer, which changes the run
height range of the suspension. The basic procedure is shown below.
Lift axle activation and movement may vary depending on the brand, configuration, and operating
condition of the lift axle control system and/or other factors. Read, understand, and comply with all
applicable operating instructions and safety information provided by the lift axle control system
manufacturer and vehicle manufacturer.
Ensure all personnel are clear of lift axle before and during vehicle loading and lift axle activation up or
down.
Exhaust all pressure in lift axle air springs and vehicle air system before working on or around lift axle.
Failure to do so can cause severe personal injury or death.
