adding a rear pro comp trac bar to the front :bs) well , I orderd it from 4 wheel parts and had them install it , cant believe they didnt catch that . I bleive this is the reason why my tracbar mount broke away from the frame . it only had about 3 inches of upward flex on the driver side before it would hit on the front diff. and it would just rest on it applying a lot of stress om the mount. :bs)
