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.

    It is an easy fit and held up well to the tork with little to no wear at all on tight technical desert trails. The only problem I had was that it does not include a master link, it was still cheaper and pulled its wait I would use it again I am on a budget

    Primary Drive 520 ORM O-Ring Chain

    CURTIS in PA

    Buy a extra master link

    Chain is great not sure if it was me but my master link seemed cheap so get a spare. my clip came off 12miles into my 30mile adventure luckily I had my spare in my kit with me about 70miles on the master link now with no problems but the clip feels better then the one that came with the chain. I'd buy it again it could have been my fault but there wasn't a positive feel when i installed the first one
