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".
With the addition of a suspension lift kit, steering geometry will need to be corrected. A Rough Country pitman arm will maintain proper drag link alignment, optimize turning radius and help reduce steering vibrations.
