Hey everyone, just wanted to say hi and ask a few questions. I just purchased a new 2012 trooper as my deployment gift. I havent been able to ride it yet as I'm still deployed. LOL But I was wondering if a 15x7 wheel with 4.5 back spacing will work? I tried searching but couldnt find the answer. Also does anyone know if the differentials need to be upgraded on a 2012 model?
