    what axles do you have?

    what air suspension do you have?

    If you don't know for sure, post a picture. Then I can tell you what it is, and how to set it.

    I have Rockwell 3.91 with a 10"frame. I believe it's the Hendrickson air ride. The spring hangers have the "H" molded into them.( spell check here ) I've set it once and compared to 2 other dogs like and kind ( sisters, all bought the same time ) and took some hints from another web site.

    One method spoke of 4.7/8" +/- 1/8 from the top lip of the spring saddle to the bottom of the frame so I set that then measured the other dogs , compared and moved it an 1/8 more.

    I'm concerned that there is some verticle slop in the air ride supply valve. This alone will affect the reaction time and settings of the ride height.

    So sure...if you know how to set it and can also give me some cross check specs to make sure I'm right....I'll take it.

    Also, I have the AL ALll suspension per the pdf I got from BMT.
