Starting with the vehicle at highest height, find the fast LOWERING end of your vehicle by pressing all four DOWN buttons at 

the same time to LOWER the vehicle. The fast end will reach the bottom of the travel first.

Slow the DOWN flow controls for the fast end of the vehicle by turning the flow control screws clockwise for the right and left 

equally (start with one turn and go to half turns as you get closer to matching the speed).

Repeat steps 5-6 until the front and rear of your vehicle lift at the exact same speed.

If you are using an AccuAir e-Level system, make sure to recalibrate the e-Level system after you have finished 

adjusting your flow control screws.

WARNING: 

Do not remove the adjuster screws with the system under pressure. Removing 

an  adjuster  screw  will  release  the  air  from  the  associated  air  spring.    The  screws  are 

retained by a small circlip in order to prevent accidental removal.

NOTE:

 Fully tightening an adjuster screw will disable that functionality for that air spring. 

For example, fully tightening the UP adjuster on “Spring A” will prevent any additional air 

from getting to that spring no matter the state of the solenoid valve.

!

Start with all of the flow control screws set to maximum speed (top).

Starting with the vehicle at lowest height, find the fast LIFTING end of your vehicle by pressing all four UP buttons at the same 

time to LIFT the vehicle. The fast end will reach the top of the travel first.

Slow the UP flow controls for the fast end of the vehicle by turning the flow control screws clockwise for the right and left 

equally (start with one turn and go to half turns as you get closer to matching the speed).

Repeat steps 2-3 until the front and rear of your vehicle lift at the exact same speed.

Pro-Tip:

 The light end of the vehicle (usually the rear) will naturally lift faster and lower slower than the heavy end (usually the front). 

Use this multi-step process to make the front and rear of your vehicle adjust level at all times.
