Re: I’ve done the caster mod should I also get upper control arms?
Which style of caster modification did you do? As far as your upper control arm questions they can only be answered by the manufacturer of the arm. Each company has a different take on what they want to accomplish with their control arm.
This link will take you to the front suspension part of my Burban project. There is more information on the next page as well. For even more information try posting your question on the suspension part of the forum.
Good luck.
