1"-2" Lowering shackles
 

Used for about a year, swapped to the Belltechs to get a little more drop. These do not require cutting/bending the bed seam, or at least they didn't on my 2013 STX. They do fit very tightly into the lower mount pocket, I used a big C-clamp to get them in.

will there level the back down to the front. I really did not want to raise my front ( heard it will decrease the comfort) any pics of them installed

It'll be close to level.

Yep.
