Hey Zack first you need to find out what size chain your Coolster has.

Second is find out what the bolt pattern and spacing is for the rear sprocket. Take note of the center hole diameter too.

For the front sprocket you will want to pay attention to the splines. I'm not sure though what sort of shaft you have coming out of that CVT though.

I think yours is similar to the TaoTao 150's .. I believe there are some better choices in gears front and rear for that style ATV if its 520 chain.

My Rhino is a 530 chain setup.. not sure what yours is. I stuck with that size chain for the added stress of the very heavy loads I am hauling. This link may help you figure that one out for sure... http://www.gizmology.net/sprockets.htm

To figure out the largest sprocket you can fit in the rear without having to hack the sprocket guard and re-weld it use this link. https://www.rbracing-rsr.com/calcsprocketdiam.html

I think I used the McMaster Carr websites 530 sprocket page for dimensions of the different amount of teeth at the time.

Keep in mind if you do go bigger then the rear sprocket guard can handle you will lose ground clearance.

I'm not a big fan of buy and try .... and not knowing if what I bought will fit. A lot of these Chinese ATV parts dealers will sell you parts they state will work, but wont work, wont fit so be careful if you don't see specs and dimensions listed. Those grainy pictures can be deceptive. I paid a little more from a dealer I could trust but got it right the first time. Do your homework.

I think a lot of us on here are a bit frugal so don't think I'm alone on this.

The guys on here are a great help... if you get stuck... ask

One last note. Steel sprockets will last much longer then aluminum. Only a concern if you are racking up a lot of miles.
