Turbo 4x4 1500 launches violently

I made a few runs this past friday night at the local 1/8th mile track... I have 325/65R18 (33x13.50) nitto's on 18" rockstars. I have the front end leveled with torsion keys. I can't apply any power whatsoever in 4wd or the front reacts violently, by picking up the front of the truck until it tops out on the shocks and creating serious positive camber and toe in and jerking left and right multiple times. 4x4 launches at only 2psi and 2500rpm are impossible and 2wd launches are worthless in a truck.... What needs to be done to allow a 4x4 launch like i see some of these trucks doing? I remember parish's truck used to launch in 4wd.... If its because of my torsion keys i will gladly remove the wheels and tires and lower it back to stock height or even lower... i did an inspection of everything... it all looks great and no bent or broken parts....

Id say drop it a little so it has that stink bug stance then go from there.

Put some limiting chains or straps on the front end to reduce suspension down-travel.

you need to drop the crap out of the front, lower it untill the CV's are AT LEAST level if not lower, it will help plant them alot better

I have a very similiar issue, 4wd launches are scary as shit and I cant steer worth a damn.

foggy also had this issue and I believe he resolved it. Check with him he was on 6" and 33 or 35s

I also suggest getting tie rod sleeves and maybe the cognito pitman/idler arm braces.

I'm also trying to remedy this issue. The limiting chains helped, but I think I need to play with their length more to get them to work better.
