I have a 2017 f150 super cab that has a 4” lift by a company called halo lifts. I have rough country shocks in the rear. I want to replace the front coil overs but everything I see says 0-3” lift max. I have lift spindles so does that mean I can get coil overs for 3”? All the suspension stuff is new to me. And does anybody know why I can’t run the rough country n3 struts I have a 2wd and that’s for 4wd but I don’t know what the suspension has to do with that?
