3" Blocks or Deaver Springs in the rear?

It looks like I'm set on the Cognito 4-6" lift. Now I just have to decide what I'm doing about the rear. I'm going to keep the front set at 4" and will raise the rear about 3" to have a slight rake. This is a crew cab, long bed truck so that probably won't even be noticeable. It will sit even when I have my car hauler attached. So what's everyone else running? I could go with 3" blocks or use the Deaver springs with 1" drop shackles and then slide air bags in for when I tow.

btw- Nick @ www.NORCALTRUCK.com is very informative! Thanks for all of the info today!

Springs are always the way to go. Even when I had 3" blocks I was still getting a slight bit of axle wrap. Springs will take care of that. My reccomendation is to start out with blocks though. Blocks are cheap and a good way to dial in what height you want. After you get yours lifted, you never know what you may think is perfect. I tried 3 different configurations of blocks and aal's before I found what height I wanted my back. When I did, I knew what size springs to order. So I'm at 7.5" front (6" Procomp and 1.5" crank), with 7" Betts springs in the rear. The springs did settle some, so I'm really only about .75" higher in the back.

Everyone that I've talked to has suggested springs over blocks. I'm not going to go to high so 3-4" in the rear will work fine for me. Most of my towing is light - a boat or double jet ski trailer but I do pull a 32" enclosed car hauler that weights a little over 10,000lbs. I'll go with air bags for when I'm towing heavy.

catch2otwo: I'll probably install it myself or bring it into work and have one of my guys take care of it. My company really doesn't do much with truck suspensions right now.
