Thoughts on 3rd Gen suspension on 2nd gen

When I bought my 2015 DCLB 4X4 I put Bilstein 5100's up front at 1.75 and it leveled me out perfectly. I went on to other suspension products, and have now put 3rd Gen TRD Offroad Complete suspension on it. Leaf springs with rear 4600 shocks, and Off Road Coils with 4600 shocks. Now I know the 3rd Gen coils will offer me an inch of lift up front, but now my truck is perfectly level at 21 inches on all 4 corners. How is this possible when 1.75 was needed to level my 15 previously. Any thoughts peeps? The only thing different is I have a Wilco Hitchgate Offset on the back with a full size spare. I was going to put a Baja Kit on my truck at 1.75 but now I'll be nose high and want to remain stock.

 

So the 3rd gens are 1" higher in the front than a second gen. They are not perfectly level though. Rear is still higher than the back. Not sure how much but I'm sure you can find measurements on here.
Also the extra weight you have on the rear is sagging those leaf springs!

 

Id say the extra weight hanging off the very rear of your truck is the reason it takes less to level you out now.

 

I was thinking that as well
