up your rear % to around 60% on dry-slick also raise the lower link mounts up higher on the chassis. How much angle is in the pull bar?(what chassis do you have?)

on our singarm car we tried the afco pullbar with a 1050 spring. All it did was let the rearend wrap way up and actually hurt forward bite. I would sayget a pullbar woth one spring about 1300-1800lbs. It helped our car more than i thaught it would. See the theory behind the pullbar is to pick the weight up off the car and load it on the rear end, if your just wraping up the rearend and not pulling up on the chassis then your not loading the rear tires. Thats just my theory though.

Mod6x,
Sounds like you have the same setup we run except we run a 900lb spring w/the AFCO pull bar. Our rear springs are 200lr and 175rr. I would bump your cross weight up to 50 to 51% cross and your rear up to 58 or 59%.Run the bottom links all the way up and as much angle
as you can get in the pullbar. That and buy new tires every week
