On your el1. It basically routes air through that “height” valve in wheel well when in “travel”.

That valve then vents air out of bag or into bag to adjust height. (Wants to keep itself centered). The oem valves should have a time delay before it valves.

The easiest way to adjust ride height with those valves is to install an adjustable link to the bogie arm. Most venders have those. (There are two different lengths i believe).
