I just put a 6" on and it worked out fine. I think you'll need a throttle extension kit, you'll prob. be really pushing it if you don't, but I think other than that you'd be fine by looking for slack in the cables. I guess I would also check your brake cable too, that will be getting stretched pretty good too, lol. Good luck and if you do, do it, please let me/us know how it went and worked out for ya!
