Hello! My son has asked for new sprockets for his quad for his birthday. He’s sent me a link to 14 tooth JT steel for front and 37 pro taper for rear. Do those sound correct to you? Also, I hear he should probably get a new chain as well with the new sprockets? Any recommendations there?

He’s able to do some work on the quad himself, so I’m guessing he knows if these will work, but I just wanted to make sure. He lost both his dad and his uncle in the last year and they were his “quad guys” for help and maintenance. I used to ride 300ex/400ex, but never did the work. Just trying to make sure he’s doing the right thing.

I appreciate your help!

welcome. I am not a sport atv person ?, but I can tell you for 100%, YES..make sure to include a new chain when replacing sprockets !. reason: they are wear together, when putting new sprockets on an old chain ?, all your going to do is wear the new sprockets down a lot faster !, sooooooo..make sure to include a new chain !.

What year is the quad? And i would suggest rk or d.i.d for chains. Depending on his mantainance schedule you could go non o-ring if he lubes it and cleans it regularly. If not i would go with an o-ring or x-ring. They will hold the little lube they get better. My .02

Stock gearing if I remember right is 13/38. So he wants to go up a tooth on the front and down a tooth on the rear. So he's looking for more top end speed from each?

Thanks, everyone!

Chain - check.

It’s a 1994 300EX.

yes, a little speed increase on both ends is what he’s telling me. It’s his first quad and he’s had it for several years now. He just wants to do what he can without spending a fortune.

Thanks for your advice!

If thats the case you should be able to buy a full sprocket kit with both front and rear and a chain. There is no need to go jt front and pro taper rear. And most sprocket kits will just be jt front and rear. Or renthal front and rear. You will want both of them to be made of the same materials so they wear the same and need all changed at once.
