ATV Sprockets

Whether you just need to replace a worn out sprocket, or you are looking to re-gear your machine, Rocky Mountain ATV/MC has a wide variety of front and rear ATV sprockets to help you get the job done.

When you are looking to make a change in the acceleration or speed of your machine, changing the teeth on your sprockets can make all the difference. If you are looking for:

  • Better Acceleration – Subtract teeth from the front sprocket, or add teeth to the rear sprocket, as this will gear your bike down.
  • Faster Top Speed – Add teeth to the front sprocket, or subtract teeth from the rear sprocket, as this will gear your bike up.

When you do change the teeth of your sprocket, make sure you run the appropriate size chain. If you:

  • Add one or two teeth to the front or rear sprocket, then add two links to the stock chain length.
  • Subtract one tooth from the front or rear sprocket, then use the stock chain length.
  • Add two or more teeth to the front or rear sprocket, then add two links for every two teeth added.
  • Subtract two or more teeth from the front or rear sprocket, then subtract two links for every two teeth subtracted.

We have a huge variety of high quality sprockets from brands like Renthal, Primary Drive, Pro X, Supersprox, Talon and more. Check them out today!

    Steel Sprockets FTW

    I've only had this sprocket installed for a few days but It still looks like it did day one.. I will probably never buy an aluminum sprocket again..

    Excellent Replacement

    I stripped the nuts on the rear of the stock bolts so I replaced them with these and these nuts are excellent.. They do their job.. The finish was actually better than expected too.. The paint didn't come off when I installed my sprocket..

  • Primary Drive Rear Aluminum Sprocket

    Primary Drive Rear Aluminum Sprocket

    Surprisingly high quality

    Okay so here's the thing, I have a street legal KTM and it's tough to find a rear sprocket that gives me top end but still has juice through the woods. I'm running a 45 tooth and that fits the bill for my riding style. Honestly though, I'm worried that the aluminum construction won't last as long (duh) as a steel sprocket but I couldn't find a 45 in steel that fit my bike. For the price though, I won't be heartbroken if I go through a sprocket a season.

  • Sunstar Works Z Rear Sprocket

    Sunstar Works Z Rear Sprocket

    Rocky in New Jersey

    Sunstar Z

    I have 124 hours on this sprocket it is still not worn out, slightly heavier than aluminum. Because the Z sprocket is thinner than conventional sprockets I had some concern about chain wear, that was not a issue at all. Excellent sprocket.
