Calibrating Air Suspension....

[HumminNBoatin']

Wait wait wait.......

I too have a 6" drop hitch on my truck. And its not enough for my boat trailer. I would not go recalibrating your rear suspension to sit lower than the factory setting. Is that what you are trying to do???

Or did you replace a ride height sensor in your rear suspension and its now sitting too high?

Just use a jack or something to put the suspension at the ride height you want and hit the button on the techII. The ride height sensors do need to be around 2.5V though.

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.

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
