Regardless of anyone's opinion on how useful the info is, thanks @Yeti_Owner! I feel like one of the few people who's still at stock ride height around here, and this is definitely getting saved. Appreciate it.

Sad to say the above posts aren't correct info, but thanks for tryin' to help guys : )
I was able to look up the service manual and get the numbers.
http://workshop-manuals.com/gmc/k_1...ns/vehicle_ride_(trim)_height_specifications/
The trim, or Z height, for these k1500 4x4's is 3.74 inches, measured between the bottom of the lower balljoint and the pivot bolt middle (see the below picture ref #13)
View media item 31093It's measured like this:
"Z" HEIGHT
1. Lift front bumper of vehicle up approximately 1.5 inches.
2. Gently remove hands and allow vehicle to settle on its own.
3. Repeat this operation twice more for a total of three times.
4. Measure "Z" height, Fig. 1.
5. Push front bumper on vehicle down approximately 1.5 inches.
6. Gently remove hands and allow vehicle to rise on its own.
7. Repeat this operation twice more for a total of three times.
8. Measure "Z" height.
9. Find the average of the high and low measurements. This is the "Z" height. "Z" height should be 3.74 inches
I know this is way late but it might help somebody else.... in the case of control arm bolts, they should be tightened at ride height, whatever that may be for you. If you're leaving the springs as they are.... tighten at that, if you make changes to the ride height.... loosen and retighten at that height. Remember, all springs will sag with time, if your 2wd isn't in spec for z-height, you might consider changing them and then re-torqueing the control arm bolts but you'll probably be sagging in the rear too. It might look funny with new springs just in the front. Maybe you only need new sring isolators in the front? These are things to consider.The biggest problem I'm finding, is the Service Manual says I have to tighten the Lower Control Arm bolts while the "Z" height is in spec.
But it's not adjustable on a 2WD with coil springs, like it is on a 4WD or HD with Torsion Bars.
So my K3500 4x4 “Z height” should measure between 5.5-5.9 inches?I don’t have a 2WD, but zoomed in on the image so maybe someone can help figure it out...
