Delete this machine from profileSelect this machineThe ATV drive system is what propels your quad forward, transforming the raw energy generated by the engine into a useful kinetic force, turning the wheels. However, just as with anything else on a four wheeler, individual components can wear out and need to be replaced. When the time comes to find ATV drive parts, count on Rocky Mountain ATV/MC to be your source. We carry all of the parts you need to keep your drive system in working order:
• SprocketsIn some cases, we make it easy by providing chain and sprockets kits, so you can replace both at a single time – this prevents one worn-out part from causing premature wear on a new component after you install it.
Among our drive parts, you’ll find more than just the top quality you need to keep your ATV at its optimal functioning level. The products we stock also have a distinctive visual flair – perfect for adding that custom look to your quad. Nothing shares quite the same aggressive, raw appearance as a finely crafted sprocket that has been engineered for top performance and designed with style in mind.
We also have the accessories you need to keep your ATV’s drive system in top shape. We have many options of chain lube to allow you to extend your chain’s useful life as long as possible. We also have drive tools to make working on your chain a breeze. Some of these tools are must-haves if you ride regularly and like to wrench on your own machine.
With major brands like Renthal, Supersprox, DID, Primary Drive and more, you know that you’re getting quality ATV drive parts when you shop with us. Take a moment to choose which category of parts you’d like to see, then click through and browse our selection.

Good chain roller. Appeared to be of good quality. Would be nice if it came with an extra bolt.

good front sprocket. Didn't last as long as I would have wished but still did the job.

I've used a couple of these sprockets now and I must say I'm very impressed! They have a good lifespan to them, so as long as you clean and maintain your chain and sprockets after rides. Will continue to buy!
