Castor adjustments

Well. i just got back from the alignment shop. Truck drives much better with some castor.....Problem was after i installed the 7" Icon i was in the negative and after using the alignment shims or spacers, whatever you call them i only have 1degree positive.(Dont yell at me if i got these numbers backwards, new at the whole castor camber deal!) From reading here these trucks drive better with 4.5-5* castor? Well i have 1* which is way better then the -2 or so i had before.

SO i guess down the road i guess 4-link will allow me to do this.

Another question though.......This may be retarded, but looks like if you flipped the radius arms upside down you could gain a bit. Probably not even possible, but just curious. :hehe

Those are the replacement arms we have and you can adjust the Castor.

Layson I've read some pretty good debates on the 4-link and 3- link topic. Mostly u and pure performance guy...nice reads

If all immwanting is more castor it seems the 3-link would be where I'm headed. I also like the look of it. Just wondering though it says up to 6" lift.....I'm at 7"....... Will I still have to use my radius arm drop brackets with those?

If you run a drop Pitman arm and a dropped track rod bracket you should run the drop frame brackets.

Those should be more then capable to adjust out the caster. Last thing you want is to put on drop down brackets, it creates more leverage for deflection of the road forces introduced into the frame. A tall lift will require them and I would only use a top quality set to make sure there is no flexing or deflection.
Those are beautiful radius arms that much is for sure. Does anyone know what a set of them go for?
Stay away from those drop brackets if at all possible they do loosen up the handling I know this first hand.
