The dont really "look" much different from your stock knuckles, but have a revised SAI to facilitate and optimize the competition alignment specs included inthe TSB and also include a dropped tie-rod boss to minimize "bump steer" due to the use of lowering springs.

Reduced Bumpsteer!!! Wooot Wooot!!! Ok, Now I HAVE to get them!

Well if that's your only issue, (after lowering that is) we use a large round 3/4" aluminum spacer under each mount for the steering rack/gear. Works well
