The upper control arm locates the top of the spindle. Its length and mounting positions decide the camber and caster the front wheel runs at, and its joints decide how precisely the spindle is held as the suspension cycles.

These arms keep stock length, so they bolt straight in. What changes is the hardware: a 1.25" FK uniball at the spindle and 7/8" FK rod ends at the frame. The rod ends let you adjust caster and camber directly at the arm, which gives you control over the alignment that a fixed arm does not.
