Another Suspension / Level Question

[TriZZZl3]

For context, I have a 2016 All Terrain with stamped steel UCA and a Rough Country 2” below strut level. This weekend, I removed the 2” level, added a motofab 2.5” above strut level, new Bilstein 5100 shocks (at lowest setting) and Readylift UCA. 
 

Before my suspension upgrades, my truck measured at 38.5” at front fenders. Now it measures 40.5”. How did I gain 2” when I only added 1/2” of level? I cannot figure it out. 
 

Yes, I’m sure the Bilstein was at the lowest setting. Yes, I removed the lower strut level. Will it settle? Will alignment settle it? 
 

Currently sitting nose high by 1”. I’ve already ordered 2” rear blocks. 
 

Any feedback helps.

Sorry for the long post

 

As I'm getting a lot older I like to spread my knowledge around. I'm only 70

 

If you install a 2.5" or any other size spacer no matter whether below the shock or above the strut spacer. 

 

The truck will go up more than the size of the spacer due to the geometry of the suspension

 

Also the geometry of the upper arm you replaced with a non-stock one could also play a part in the height. I would contact Readylift and find out if  the arm is different that the stock besides being of a stronger material.

 

On my 2017 Silverado 1500 2WD I had a 1.75" spacer that leveled the truck but not enough so the rear end was a little higher, about 3/4"  higher.  So I bought a 2" billet spacer and installed it truck went up a little less that 3"

 

I know a friend of mine installed a !/2" spacer on the lower arm below the shock and his truck went up 1"

 

Maybe someone here has the formula for the geometry and the height difference.

 

Or you can Google or Bing it.

 

Actually the 3/4 ton trucks have a different geometry, have you noticed when you drive your car in a garage the wheels squeal? it because the engineers put in understeer (move the steering wheel with less turning of the wheels) to the geometry to make it a little harder to spin the car. Most new vehicles have Variable Steering because it makes it harder to turn the steering  wheel at speed and easier to turn at lower speed. In this case they accomplish the same as with mechanical means. 

 

There are books written about car steering geometry, I used to have one when I autocrossed. Go to the SCCA website.

I’m aware of this. The 2.5” leveling kit is a 1.66” spacer. I do like your thought on the UCA. That could be a factor.
