In my opinion no but I never tried a tuner first which would have adjusted my settings. I went on forums and listened to people who said regear or your truck is not going to last long. I talked a gm mechanic friend who told me dont do it but it was to late. Look at it like this $400 for a tune which you can easily take everything off your truck without any worries versus $4500 and you changed the mechanics of the truck which it will be harder to go back stock due to the higher gear ratio. Im no expert just trying to pass my experience along to others. At the end of the day its your truck your money
