If you look at specified range and then your actual readings of what your truck is, appears to be out of the specified range on a few points. I read that printout just like I would a blood panel work up where it tells you your actual readings then what range they should fall in. Like I said, it could be just the way it is written by that program and I am off base. But it appears a few areas are not within range.
Maybe you should stop reading blood panel work-ups.

I'm thinking it might have been in that range to begin with(stock), and after the 2.5" lift 2 degree shims just put it right back there.
I guess he could use what some others have used, 2.3 and 2.6 degree to get a little more out of it.

As far as centered? I did that when I did the level/bushings.Why would we recommend more caster if it is in spec?Just asking because I don't really understand all the nuances.The tires seem to be wearing OK.

Nvmnd..I see that they are both in range...I never was good at math.See this is why I posted here,I'm learning.

I'm just going off of what he said in his first post. Said he did all the suspension work including Carli caster shims. Maybe it wasn't "he" that actually did it🤷🏻♂️. Maybe he'll come and confirm that soon.

I was looking at the individual side casters,I see now that maybe we are referencing the "cross caster" in the 3rd box?

Having more caster increases tracking stability and reduces the potential of death wobble. Many people will intentionally set it at the most positive end of the range, or even over.

So,would this be adjustable with the bushings I have,or do I need new bushings?

Valid question!
All these numbers can be foreign to those who haven't worked with them.
Think of caster is as the fork angle on a bike or motorcycle. If the fork was straight up and down, it would have the stability of a shopping cart wheel (visualize that, if you will). But on the other side, you have a chopper with very slack steering. At speed, it can be very stable, though it won't handle so well at low speeds. Of course, the goal is to find the middle. Before the days of power steering, you didn't want much caster because it made it harder to turn at low speeds. But with power steering, it's ok to have more caster. I am over simplifying this for the sake of visualization, but that's the gist of it.
