I had a 2006 F150 and put 31's on it with a 2.5" leveling kit and it had a fiberglass leer cap. The problem was it was almost unlevel. So I bought a 2009 with 33's and I ordered a 2" leveling kit and this also has a cap. Has anyone else done this and what should my exspectations be as far as being level with the cap? Gene
