Re: steering corrections
Shawn, my point was that with a small lift (4" or less), you should not get ANY bumpsteer. A steering arm or any correction that raises the position of the rear ball joint on the draglink to a point that is equal to or higher than the pitman arm joint will cause bumpsteer. Its basic geometry and physics - I can go into more detail if you want. Raised arms are supposed to come in 4", however, the Black Diamond arms are 5" and will result in bumpsteer on a 4" or less lifted truck. He needs 3" max. So ideally a 3" dropped pitman arm, but a 2" draglink or a spacer would work well too. Just some info we've gathered over the years from building various trucks.
Turning radius is only slightly compromised at less than 4" of lift. With 6", yes, crossover for sure. As for steering with full droop, this occurs only during 4wheeling, and with a small lift, the droop is much less than with a higher 6" or more lift - so the effect is significantly less. And if the front sway bar is still connected, the effect will be negligible. I like the idea of crossover steering, just depends on what he intends to do with his truck.
