After putting it off for a while I have finally decided to spend the money on lifting my truck. I'm going to go with a 6" with either 33s or 35s. I know most people say to re gear when going with 35s even though some people have gone without it and haven't had problems. But I'm wondering if I really need to regear since my truck is supercharged. Is not regearing really going to hurt anything? What are the cons to not regearing?
