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.

    Great Product!

    Great product! The durability is amazing and installation was easy due to the precise fitment. I have ran nothing but Primary Drive sprockets and chains on my race quads over the years with no problems! I wouldn’t run any other product!

    This 520 chain is holding up well with about 40 hours of use on a 200 two stroke and has stretched initially a bit but not after break in.

    Primary Drive 520 ORH X-Ring Chain

    Nice chain

    I bought this for my 09 CRF250R. Seems well built and heavy duty. I was a little worried about fitment on my bike because of the added width from the o rings, and possible rubbing on my case. But everything fits good and still has lots of room. I dont have a chain press, and I was still able to pinch the master link with a pair of vise grips and install the clip.

    Great chain for the price

    You can’t go wrong with RK. Chain did stretch a little during my first ride. Made small adjustment and has been fine since. I ride mostly trails gncc style but not a racer. Highly recommend this product
