If RK did not want a final check during the alignment then they would make fixed arms and not adjustable.

You absolutely want to make sure that the person or shop doing the alignment actually takes the time to make the final adjustment.

As far as the jam nuts go we recommend using lock tite on the jam nut after the final adjustment is made and tightening until you can't tighten anymore. Some of the jam nuts are very difficult to get to while the arm is installed so it may require removal of the arm in order to do so.
