OK here's the deal, I have a 6" lift with 35" tsl's. the lift is a superlift and I have the 4" steering arm and the 2" drop pitman arm and dual shock stabalizer. but I still have bumpsteer, not as bad as it was with just the steering arm and no pitman arm but now with the added two inch drop pitman arm it is still there. My tie rod ends are brand new, drag link is brand new. the only thing on my steering old is the box is that the problem? please help. also it is very sluggish to turn, say like I am trying to dodge something I would have to crank the wheel and it would turn the wheels very slowly.

When you put the lift and other parts on did you tighten up everything with the rig sitting on the ground?

Yeah what wayne said... and from what I have heard is Superlift has springs that have shims already attached... which means that you HAVE TO have the truck aligned afterwards. So this could also be playing into the mix of things

I of course put everything on in the air but tightened it all down on the ground does that make a difference? I had it aligned but it didn't help at all. If it is bad to tighten it down on the ground can I just undo everything and retighten it without the load on it?

One of your big problems is the frame is more than likely flexing. If you do not have a steering brace like the one ORD sells then you will always have problems. Get that first and make sure that your frame is not cracked around the steering box. This should fix 90% of your problem. If not two words,
crossover steering.

I thought I was wrong once,
but I was mistaken
 
You always want to tighten everything with the load on it. Someone had a post in a couple of days ago and tightened everything without the load and had the same problems and was told to loosen everything up and then retighten with the load on it. It cured most of their problems.
