Springs are in thanks to James for all the help (btw ....Dam was it hot Sunday!)
To review now sitting on....
MarkMC original Liftmeister 2.5" lift all the way around
And now new Moog 81114 springs in the front
and the Z71 Tahoe springs in the back.
Here's a side by side of the front springs ( I think you can guess which one is the NEW moog spring)

When I first installed the lift last year (same lift and tires factory springs)

Taken this afternoon (same lift and tires new springs listed above)

Measurements
(F=Front B=Back L=Left R=Right)
These are measured from ground to top of wheel well arch through center of wheel. It wasn't really level when I took either measurement but I think this is pretty close. I also had about 150-200lbs (guessing here) of tools etc (steel spare on my tire carrier) in the back of my truck.
BEFORE AFTER
FL 36 7/8 37
FR 36 5/8 37 1/2
BL 35 3/8 36 3/4
BR 34 1/2 37 1/2
Both sets of springs had a 17mm coil diameter
The stock springs I had are 9 coils and 405 mm long
The moog 81114 springs where right about 10 and 1/4 coils by comparison and just about 15mm longer (420mm)
I currently have no extra weight on the front of my truck but will have MDB Rad and oil pan skids once they get shipped but as it sits now we measure about 1/2 an inch of down travel.
The ride is STIFF! I don't mind it but if I had been given the choice for the same price I would have gone with something with a little bit more give. I think I'll get used to it as time goes on and they'll settle in a bit. There is very little body roll (if any) taking corners at speed which is nice (and a little odd feeling) but there's also not a lot of give when you hit a bump. I think its stiff enough that a friend who had been in my car on a regular basis would notice after the first big bump (think of a moderate speed bump without slowing down below ~20mph). I remember when I first bought the TB thinking it felt like an old Cadillac kind of bouncy / floaty (part of that was rear shocks that were on their last leg) and over time I've just gotten used to it. I think if it road this way when I first bought it I would have just thought "hey its stiff, well ya sure its a truck not a minivan". Hopefully that gives you some idea how this feel so far at least in my opinion.
It is noticeably higher off the ground (my seat of the pants feel not so much the measurements) I almost trip a bit jumping up into it now with the extra inch or so.
Overall I'm very happy, the Z71's in the back are a godsend, I was sagging BAD with all that stuff in the back (even worse at TECORE last month...) this solved that and then some.
Now.... I really really really need to get this thing out onto the beach!
