Flat leaf springs

I have a 2015 tundra with a 3/1 level kit. My rear springs are just about flat. No U shape to them. Anyone know why?

 

Ditto^^.....Seriously Mike, If you have the time, take some pics. Curious as to what gave you the 1" lift in the rear. This should be an easy fix.By the way, who did the 3/1 and do you know the brand? The more info you can give , the better.

 

I'm going to guess that it's a block between the axle and the bottom leaf spring, that seems to be the most common small lift. Flat springs are pretty much the norm as well, they ride better. The 1st generation Tacomas rear springs even had a negative arch, all the off-roaders were like WTF? It also allow for droop, a leaf pack with a huge arch is really only going to allow for flattening (compression), they're not going to arch much more. A flat(er) spring is going to arch both positive and negative.

 

They're flat from the factory. They also angle it slightly up from front to rear. This makes it smoother as well.
