im thinking of dropping a tooth on the top gear on my mxz for better low end pull, and i want to know what size chain i will need, and what size gear. *if i only drop one tooth will the stock chain i have fit, or will i have to get a different one. and if i get a different chain what size wide will i need. *i see that there is all kinds of different gear and chain sizes, like 11 wide and 13 wide and whatnot. *all i want to do is drop a tooth on my top gear, so what size gear and chain will i need??

Your sled will be a 13 wide, all you need is the gear, you might also want to buy a couple others each one tooth smaller and try em, most sleds work well 2 down as you USUALLY get the same mph but better acceleration, good luck.

ok thnx ballsout, are the erlandson performance gears good?
