Hey guys, I'm interested in picking up my front end on my truck. Basic info, truck is a 1998 Cheverolet K2500 4wd 8Lug. It has a Superlift on it right know with Rancho shocks. I didn't put that on and its on 6in blocks in the back. The front has the corrosponding front lift components. My question today is: Should I use Coil Spacers or Torsion Bar Keys?? When I search for Coil spacers it only is availabe in 2wd making me think that it won't work with 4wd.. Is that correct? Can anyone confirm?? Also when I search torsion bar keys I can't find any specific to my 98 K2500 4wd 8 lug. Can anyone point me in the right direction?? Thanks for taking the time to read this and help me out!
