I bought a used 08 Supercrew with a 6" ProComp lift but the rear end is a little lower then the front. Has anyone else experienced this with their truck? What was the solution (Shackle, Add A Leaf, etc.)?

 

very very common.

You can buy either a bigger block (not recommended), or buy an add-a-leaf.


You can pick up a 1.5" add-a-leaf on eBay from a company called Autosprings. Goes for about $140 shipped inside the US.


Autosprings has been making suspension stuff for these trucks since day 1. I had their 3" blocks and their 2.5" front spacers. All quality stuff.
