Rear spring ?

Im a 2016 TRDOR DCLB. I have a hirise camper shell, a wood frame platform (about 30' of 2x10 and a 3/4" sheet of plywood) and all my camping gear and tools that ride around with me. I measure about 19-20" give or take hub to fender. Stock as I understand it is 22". I am toying with the idea of the Dakars with or without an AAL. I cannot yet afford to lift the whole truck but my thought is that the Dakars will basically put me back to stock plus maybe a itsy bitsy bit more. Am I right or wrong? Will I need the AAL to get stock height or will that start to get me above stock height? Does anybody have a similar set up? Is the CS047R the right spring even though it doesn't show up on all websites as fitting my truck? These things seem to range anywhere from $200-$450. What am I missing here on the price?

 

#CS047R is (1) leaf spring. You need to buy quantity (2). Most places sell them individually unless specifically says a pair. You'll need new bushings and longer u-bolts as well.
