EM36440 MAK5866-90054007 Leveling Valve

It helps maintain a consistent ride height by metering air in or out of the suspension as load conditions change. This supports better handling, stability, and a smoother ride by keeping the chassis level. It functions as an air suspension height control valve to keep suspension geometry in the proper range.

Match the part numbers and cross-references used on your vehicle, including MAK5866-90054007 leveling valve and any OEM-equivalent identifiers. Also confirm the linkage style, port configuration, and mounting orientation so the heavy-duty truck suspension valve connects correctly. If your suspension height control and air lines differ from the original setup, fitment issues can occur.

Yes, wear or internal contamination can prevent proper sealing and lead to slow leaks, constant venting, or delayed height correction. These issues can show up as a truck sitting low on one side, cycling air frequently, or struggling to maintain a set ride height. Replacing it with a replacement leveling valve EM36440 can restore proper air suspension height control and reduce unnecessary compressor work.
