I am getting some 35x12.50 super swampers, and I dont think that my gears now (which I am unsure of, maybe 3.09 or 2.73) will handle them. Would 4.11 be good for me? I do some towing and romping, no rock crawling or anything like that. I am really unsure of what gears to go with..what would you guys reccomend? And can you guys help me with exactly what I need to purchase to do this? Do I just need to buy new ring and pinon sets or so I need more stuff than that (besides the gaskets and fluid). Should I do it myself and learn, or have someone else do it for me? How many hours of labor should it take, so I could get an idea of pricing, my mechanic is about $50 an hour.
