So i just bought a 2009 jeep unlimited sahara 4 door with 22 inch black boss rims and 37 inch wheels for 25 grand... it has 50 thousand miles on it. so im thinking i either got a really good deal or got ripped off. Let me know what you think, real question is do i need to change the gears out and if so how do i do this gimme a website please to tell me how. i dont know if its stock but i dont know if the previous owner did it and i dont want to ruin this jeep... its my daily driver and will be doing alot of off roading probably. BTW i get 11.8 mpg lol! Thanks!
