I have an 05 fx4 supercrew 110***miles and I'm going to be buying shocks and struts. This is the first time I've had to do this so I'm not sure what I need to buy. My truck has a 6" suspension lift. What do I need to buy as far as shocks, struts, should I get new coils? I'm on a budget but I want to make sure its right and isn't a p.o.s.
