ATV Chains

ATV chains require two points of maintenance: regular lubrication and length adjustment. You shouldn’t neglect either. Lube keeps the chain moving efficiently (something that is important at the high speeds a four wheeler demands). It’s also important to keep dirt and particles out of the chain, which causes increased wear. Over time the wear on the chain causes it to naturally stretch. Adjusting it keeps it at an appropriate length to reduce unnecessary wear.

However, even with proper maintenance, there comes a time when a quad’s chain needs to be replaced (as with all ATV parts). When that time arrives, we hope you’ll think of Rocky Mountain ATV/MC. We carry a variety of ATV chains to fit your needs. We stock major brands like DID, RK, Renthal, Primary Drive and more.

When shopping for a new drive chain, one of the most important things to consider is the seal. Standard chains include no seal and require constant lubrication to run efficiently. While less expensive, standard chains will wear out more quickly if you neglect lubrication or have intense riding demands. O-ring chains include a seal for the factory lubrication, reducing the amount of maintenance that is required. The O-rings also help keep dirt out, extending the life of the chain. X-ring chains are similar, but the cross section of the seal is shaped more like an X than a circle. This creates a two contact points instead of one, ideally improving the seal while reducing friction. However, X-ring chains tend to cost more than O-ring chains.

Whatever your preference, you can rely on Rocky Mountain ATV/MC when you’re looking for ATV chains. Browse our selection now.

    wide chain

    I have not ridden my bike with this chain yet and, I'm not sure anyone else reviewing this product had the same problem but, this is a very wide chain. It's almost three mm wider than the chain I removed and is causing really bad friction on the chain guide. I'm sure after a couple rides it will wear down the guide so it will become less noticeable. However, it's bad enough where I think I will definitely notice it riding. If I were trying to go out and finish well in a race, and I'm not, I would probably return this chain. It takes a lot of effort to turn my wheel by hand. Other than that, it does seem like it is and will be a reliable product.

    Primary Drive 520 RDO O-Ring Chain

    Very impressed with this chain, has not needed adjusting since the first couple rides. About 30 hrs on it so far, MX only, will probably last another 20 at least. I will get their X-ring chain next time, less rolling resistance. Very good value from Primary Drive.
