probably a 14 in the front and what ever is stock in the rear, the 14 will give u more bottom end

Go with the 13 tooth in the front. All I do is ride the dunes with my 400. I run at 13 in the front and it gives me plenty of torque to make it up pretty much anything in 2nd gear... some things in 3rd. I can even do 2nd gear starts for drag racing.
