I have a '2500' 2000 silverado that I boosted the torsion bars to the next step up by replacing them, and added a set of Timbrins for the plow and put some larger tires on the truck. My question is about the "A" arms, is there a difference between the 3500 and the 2500 in regards to caster and camber adjustments. I cant seem to get it just right, its almost as if there is not enough ajustment left . Are the 3500 arms the same size (would they fit on a 2500) and do they have more room for adjustments?
