Just got my Thuren 3in Track Bar and (what a beefy piece)I need to get the front of this 4x4 done. I have been told zero toe, and about 4.5 degrees on the caster...

 

little bit of toe out jus to center the wheel and 6 plus on the caster if you can
sometimes its hard with non adjustable arms

 

Hmm, usually on all vehicles you want a bit of toe in. Toe out causes the tires to want to steer in their own direction, allowing the feel of always correcting for straight. Having toe in allows the tires to steer towards/against eachother and keep the vehicle straight. JMO though...

 

Don Thuren is the one who recommened these specs

In general, the more caster you can put in it the straighter the vehicle will track on the road but the heavier the wheel will feel and the more the wheel will want to return to center after turning a corner. Caster will not cause tire wear issues to if you can get 5 or 6 degrees out of the stock arms then go for it. Of course, there is a point were you would have too much caster (every ride a chopper?) but that is probably not attainable with the stock arms and adjusters.
