Rear 5100 or 5125 for 2'' AAL

Looking to go 2.5 on my front 5100's and a 2 inch aal in the rear (non tsb leafs) to level my truck. On DownSouth they have 3 different options for the rear. It states the 5100's for the rear are 1-1.5 inches of lift and the 5125's are for 2-2.5 inches of lift. So I need the 5125's in the rear with a 2 inch aal? Just making sure. Thanks in advance. Tried searching and got so much random stuff but no definite answer.

I have a 1.5", 3 leaf aal with TSB springs and 5100's on for years now and the 1"-1.5" 5100's really limit your down travel alot. I have the 3-4" 5100's with longer rear bumpstops ready to go on tomorrow. Much more down travel but you NEED to get longer bumpstops so you don't top out your shocks. As for 5125's, they seem fine length-wise for a 2" lift but only have a 90 day warranty, whereas the 5100's are lifetime warranty.
I'd say if your gonna wheel your truck, get the 3-4" 5100's and some longer bumpstops. Just my 2 cent
