This pitman arm works on 2003-08 models with the factory steering box. If your steering box has been upgraded, this pitman arm will not fit and you should order the 2009 model pitman arm. To determine this, measure the sector shaft spline. The 2003-08 model will measure 1-1/4". The upgrade will measure 1-1/2".
A Skyjacker pitman arm is built to last. With the addition of a suspension lift to your vehicle, steering geometry will need to be corrected to maintain complete turning radius and to prevent bump steer.
