Right now on my 2015 I have a level up front with stock shocks and the Bilstein 5100 shocks in the rear. I am about to remove my level up front and my factory rear lift block.

Question 1
My rear Bilstein shocks are the 4wd versions and once I remove the rear block will I need to swap out those 4wd 5100's to the 2wd 5100's.

Question 2
Would this set of front and rear 5100's off of Ebay work. With it being for a 2wd would it lower my front of my 4wd truck lower than stock. I am fine with that because I don't need ground clearance at all and I am about to go with some shorter/wider street tires than my current KO2's. http://www.ebay.com/itm/BILSTEIN-24-...hYnW~5&vxp=mtr
