X2 This is how mine sat.

I have a RC leveling kit and a set of their 3" blocks on the rear of the truck. When I installed the front leveling kit, it was actually a little higher in the front than in the rear and looked funny, that's why I installed the blocks. With the level and blocks, the truck has a perfect amount of rake to it and is perfect for towing. The truck sits level when loaded and doesn't have the front end pointing up in the air like it would without lifting the rear after the leveling kit install.

A 3" rear block will only give 1 3/4" lift in the rear. Stay away from the ReadyLift blocks, they cost way to much money ($160.00). The Rough Country kit costs much less, around $50.00 for the same exact size and tapered rear blocks.

An issue you may run into adding a 3" rear block is the shocks may bottom out on you because you are stretching them when adding the blocks. To fix this you can either buy longer shocks OR get a set of ReadyLift relocation brackets ($60) for the rear shock mounting points. I added a set and they work great, my shocks do not bottom out with them, they did without the brackets.

For anyone thinking about doing this, the RC 3" block and u-bolt kit part number is : 6564 (they are tapered to correct angle)
The shock mount brackets are ReadyLift : 67-3809 (recommended with 3" blocks)

You can also lift the rear up to 2" by adding a long leaf to the leaf pack. If you tow or haul heavy loads this would be a much better option than a rear block.
