6 Degrees? I maxed my caster out negative and when I took it to the shop, it was 3 degrees back. Now that was with ball joint spacers so I did lose some of my ability rock the spindles rearwards with vertical caster but are you sure about 6?

Anyway, search on this forum and you'll find some info on aligning your own truck.

As for caster, you just need both spindles leaning rearwards. I just got my relay rod done and one side is back 3 degrees, the other 1.5, and the truck drives straight as an arrow. Caster simply encourages the wheel to return to center and fluctuating a few degrees of zero doesn't make a large difference.

If you truck is sitting level, and you installed the lift brackets straight, than look for symmetry between the adjusting nuts on your lower a-arms. If one side of the rear facing hardware is biased outwards (which is should be), the other side should be biased outwards too.

When you think you have all the specs in, take her for a drive. That will tell you if you have done it correctly or not.
