Help Identifying Rear Suspension

Hi all. Bought a 2014 Trd Sport long bed a few weeks ago, and I’m trying to identify if there was a leaf added in the rear. It has a total of 5 now. The rear seems to sit quite a bit higher than the front, with 265/70/17 tires shown here.

Thoughts? Was a leaf added?

 

The 3rd leaf isn’t stock.
It’s been added.

 

Thanks TnShooter. Can you tell how much lift it gave the back end? Thinking about lifting the front end 1.5-2in. Too much?

 

A measuring tape will tell you what you need to know.....

Thats a single 2in AAL on a 3+1 stock leaf pack which has probably netted ~ 1.5-2in of lift from stock in the rear

 

you 'll have to forgive me but i couldnt help it....
