I am looking to buy a drop kit for my 2013 stx std cab teuck. My question is, I am looking at buying a 2/4 kit, but using the front struts I can actually go 3" which I plan to do. Should I decide to go more to a 5" drop rear will I have to buy a whole different rear setup, or can I just buy say the hangers and get that additional inch?

 

The 4" drop uses a 2" lifting hanger.

The 5" drop uses a 1" lifting shackle.

You would just need to buy the shackles and take out the hangers.
