B2400-B04 AIRman Air Control Kit for Steerable Lift Axle Applications (HAC-SSI)

(5 customer reviews)

22 in stock (can be backordered)

Used in Steerable lift axle applications.

This air control kit is made by AIRman which directly replaces HAC-SSI formally from Hendrickson. The face of the panel does not bear the Hendrickson name but other than that, is identical to the original HAC-SSI. This panel also replaces flip switch model R-017513-00.

The Hendrickson version of the HAC-SSI is discontinued and is replaced by LC-SSI, which requires new plumbing and the panel size is different. We stock it also, and you can find it HERE.

This series air kit line has been designed to provide excellent reliability in your lift axle application.

Regular inspection, as a part of your preventative maintenance protocol, as well as daily operation checks should be performed.

    Seems to be direct replacement, wish it had some kind of paperwork with it, it has a valve of some king in the kit that my truck doesn’t have in the system, and I’m not sure what it does, or if it’s needed.
