I have a 2004 silverado rcsb 2wd with 2 inch drop shackles. I am wanting to lower the back of my truck one more inch but I am not sure how to lower it one more inch. I am trying not to go with a 2/4 drop unless I have to. I know I can lower the front 1 inch with springs but how do I go about the back of the truck.

 

Your shackle adjustable 1" to 2"?? If so just go with a 2" hanger and then you can udjust between 3" and 4".

 

Yeah that sounds like it might just work.

 

Most shackles are adjustable, so all you need is that 2" hanger.
