.85 or 1.75.... I keep going back and forth

a 1" block won't be too bad, but an AAL would be better, it'll just make the back a bit stiffer...up to you. If I were going to the trouble of installing the 5100's, I would at least put them at 1.75. I installed 5100's all around with a 2" AAL (No TSB) and eibach springs in the front at 0.85 on the 5100's, and got 2"... I personally think it looks "right" for these trucks.

 

Pics?

 

I already have my TSB done from the factory, but they have sagged a lot!.. Probably from hauling my Renegade 800 around (600lbs dry weight) I ended up going with Beefed Taco 1" blocks (in the mail). Ill try to get you some pics of before (.85 & tsb rear) and after (1.75 & 1" block) if you'd like.
