Ive been thinking about 4 linking also, have you found a kit?
T bar bolts out with 3 inch shackles + 1 leef spring removed with 20x9 eagle 050
I must be a lot lower than y'all are. I'm running 305/40/22s and have about 3 inches from top of my tire to the bedside. And no I can't buy a kit I have quadrasteer. But I pulled my bed and cab today. Cab for studs and bed for the four link. I'll try to get some pictures up while I'm doing all.of this.
Waiting on my shackles but here it is so far.
Show us some pics..
