How air helper spring spacers work
An air helper spring sits beside the main suspension and adds support when the load grows. A spacer raises the air spring mounting position so the spring sits at a different height, which changes how the ride and the load level behave. Fixed-height spacers keep that change the same every time, so the mounting points have to match the design before anything is fitted.
Before fitting, measure the axle mount points and confirm the bracket spacing is correct. Check the air lines and fittings for wear and cracks, since a spacer change can put extra stress on them. After installation, inflate the springs slowly and check for leaks at every connection, then recheck fasteners after the first drive.
- Measure bracket spacing on level ground
- Inspect air lines for chafing or cracks
- Check all fittings for leaks with soapy water
