factory suspension height

[sillywillie07]

Does anyone know the factory ride height for 2011-16 2500hd?  The old 2500 hd, my old 2006 had a factory z height spec you could adjust torsion bars to.  It was bottom of the knuckle using a level to the center of the bottom control arm bolt.  Just wanting to check mine after dealer played with it.  thanks

I have a 2016 2500. I just had a level kit put on at the dealership. Based on their measurements front is 40” and rear is 43.5”.

Where did you find it?  What is it (the factory z-height)?

factory z height is a measurement on level ground using a level and tape measure.  You put the level on the knuckle bottom where the ball joint nut is.  Place the level on the machine surface of the knuckle.  Use the level and hold it level.  Measure from the center of the lower control arm bolt at the frame of the truck, to the level.  It should be between 5"-5.5".  need to check both sides.  Service adjustments allows .5" side to side.
