I recently bought my very first jeep, which is a 2013 Wrangler sport. I'm thinking about a 3.5 Terraflex long arm lift, with 37' pitbull tires. Im gonna regear to 4.56's but do i have to replace my axels too? im planning on doing that eventually, but being as im 19 and money is tight, i dont want to do anything i dont have too. Any advice?
