What I did was basically a MORE shackle reverse, but used wrangler spring hangers in front(4" drop) and the shackles are through the frame(4" length) . Seamed alright till I put some trails on it, it's fine on the trails,but on the road she turns a straight road into a slalom course. I plan on SOA next summer(ran out of weather)so for now the wedges might just do.I can't shorten the shackles much more since I put them in the frame(centered)and I'm lookin' at about 2" below frame. I'll be able to adjust for the angle with the SOA now that this has raised it ugly head. Man,I thought I spent enough time on that front end but what can I say.Thanks for the info,BC.
CSP,that's what I meant the "caster",right now my pinion is up4-5 degrees, with wedges it would bring it back down and I'd get my caster back.Also Avalanche(sorry 'bout spelling)has steel wedges instead of aluminium,good point.
