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.

  • Primary Drive 520 ORH Gold X-Ring Chain

    Primary Drive 520 ORH Gold X-Ring Chain

    Bryan in MI

    Lasts for the entire riding season

    I'm a dual sport rider and put on between 1500 - 2000 miles/year of all dirt, two track, and single track riding. The chain and sprockets last an entire season without any issue. Chain stretches very little and sprockets wear well. Front sprocket is the first the show wear, but I change the whole assembly for the cost. The only issue that I have is that they typically send a chain that is a couple links longer than I need. I have a chain breaker so not a big deal. I believe they have the 120 listed when I need a 118.
