I use the long arm upgrade kit with about 4" lift. I did it mainly to get a better ride on and off road . I do like it alot . I still have short arms in the rear that are adjustable and flex. That along with OME shocks gives a great ride . I am still going to change to a different track bar and pitman to flatten out dragling and track bar angles to improve it more.
