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.

    So far so good

    I haven't had much time on this chain but so far it has been good. Gold looks good and it stretched on the first ride, haven't had to adjust it since

    Excellent Chain

    Used this chain on my '06 GSX-R750 track bike. An excellent chain that easily withstood the abuse that trackdays will give a bike.

  • Vortex 520 MV3 Chain

    Vortex 520 MV3 Chain

    Steven in CO

    Do not waste your money!

    Bought this chain and new front and rear sprockets at the same time. Installed as a set. I got 13 hours out of chain. It stretched so bad I had no more adjustment left on axle. Also had 2mm of slop in each sprocket tooth. I called Vortex and was told 1 month of use is the expected life of this chain. I can buy 4 cheaper chains and get 4 months use for the same $ I wasted on this chain. Chain used on a 2013 KTM 250SX
