I have a 97 Ram 1500 4x4 with 7.5 inches of lift. My 35's look tiny so I want to get 37's. I have stock 1500 gearing and I know people say you need at least 4:10's for 37's but I dont want to re gear. I know my gas mileage would go down a lot but other than that would there me any mechanical problems if I ran them with my stock gearing? Thanks!
