Calibrating Air Suspension....

[HUMTECH]

Tool overall height is 5 3/16"

Thank you very much for your time and effort HUMTECH, much appreciated. I will be writing that in my service manual for the future questions here and hopefully has answered agood1's question and they can fix their problem in the first post.

There ya have it folks 5 3/16" OAL from the man himself

Thanks again bud, Ed

Thanks for all that have posted on my question. Sorry I did not get back to read this sooner.
I have a couple more questions.
1. If the tool is 5 3/16, where would I take that measurment if I don't have the tool....or if I make a homemade tool.

2. Can I just put a the truck on my lift and lower it down to the desired height and let it recalibrate from there? Or maybe even use a floor jack under the trailer hitch?

Thanks

Measure from the metal flange at the top of the bumpstop to where the bumpstop contacts the diff housing. Yes you can just set it at this height by lifting on the bumper hitch and calibrate from there

Thanks, I'll give it a try and post the results.

Done,

I used the voltage readings on the height sensors to get it where I wanted it....maybe a little below stock, but it should work.
My readings before were 2.87 and 2.94
Now they are 2.18 and 2.22. And you can actually tell a difference when you hit the ride height adjustment button....and the voltages go to 3.04 and 3.06
Thanks for all your help.
