    Hey everyone. Bought myself a 2004 step deck and have a question on the valve box. Anyone have history using these? The large lever seems to be ride height, but it doesn’t change much. I’m unsure of The gauge in lower right that is rusty and clouded over. Any help deciphering this? I always ran spring ride so getting used to it. I know the black knob locks the axle when I slide (although right now the pins are stuck because it’s been in spread without being exercised) and the other valve raises and lowers the trailer for sliding. thanks for any info.

    Large lever is NOT your ride height, or at least I doubt it is. Our trailers with a tag axle that lever controls pressure to the tag axle. So I'd guess it's to adjust pressure to an axle. If its just a tandem spread not sure why
