Delete this machine from profileSelect this machineATV axles. Are they all they’re cracked up to be? Yes. Will a damaged one really make a difference? Yes. Does Rocky Mountain ATV/MC have what you need? Yes.
The truth is… ATVs are highly sophisticated machines designed for speed, maneuvering, utility and all-around fun. And like any vehicle with four wheels, they’re designed to accept heavy loads. An axle that is straight and in proper working order will keep your machine moving forward as efficiently as possible. But if not – well, you’re going to run into problems. So if your axle is bent, damaged or simply worn out, don’t wait around for it to start giving you grief. Get it replaced pronto.
Need to know where you get a new one for your quad? Right here! But you’ll find much more on this page. Aside from axles, you’ll also be able to pick up axle tools. If you’ve ever replaced one before (or simply talked to someone who has), you know that removing those nuts and bearings is no easy task. That is, it’s no easy task unless you’re equipped with the right tools for the job. They’ll save you plenty of time (and probably a few choice words as well).
And speaking of bearings, why not replace them while you’re taking care of your axle problem? We’ve got several great choices. And since we always offer our products at the lowest prices, it’s a great time to pick up a few extra parts like rear axle bearings. Not quite enough for you? Pick up a new bearing housing as well.
If it’s extra width that you’re after, you simply can’t go wrong with an adjustable-width axle. There’s not a better way to extend your existing wheels out a little bit. But that isn’t the only solution we have on hand. We’ve also got a great selection of wheel spacers – nothing’s easier when it comes to adding an inch or two to each side of your ATV. If that’s not a good fit, you might want to consider extended rear wheel hubs.
So if you’re after axles or their associated tools and bearings, you’ve come to the right place: Rocky Mountain ATV/MC. Click one of the options above to take a peek at what enhancements are in store for your ATV.

I installed the Modquad Double Locking Axle Nut during my 400EX rebuild and have been really happy with it. Simple to install and adjust compared to the factory setup. Everything went together smoothly, and the double-locking design gives me confidence that it's going to stay put. The machining and finish are excellent, the threads are clean, and it looks great on the bike. It's one of those small upgrades that doesn't get much attention, but it makes maintenance easier and gives the rear end a much cleaner look. I'd definitely buy it again.

The Tusk Adjustable Width Racing Axle is a rock solid upgrade that delivers performance, durability, and flexibility all in one package. The adjustable width is a huge advantage it lets you fine tune your stance for stability, cornering, or track conditions without needing extra parts. Installation is straightforward, everything fits cleanly, and the machining quality is exactly what youd expect from Tusk: tough, precise, and built to last. Once installed, the rear end feels noticeably more planted and predictable, especially under hard acceleration or aggressive riding. Its a major confidence booster and a serious value for the price. If you want a dependable axle that improves handling and gives you tuning options, this one is a fantastic choice.

High quality! Better than the original. Easy to install with the right tools. Sorry guys, you need more than a screwdriver and crescent wrench.

Seems high quality. I think I've used these before. I ordered this for a 18 Polaris Ranger 900 front inner. Didn't fit my application, but I kept it anyway.

The Tusk Racing Axle Replacement Snap Ring is a simple but essential part that delivers exactly what you need: a perfect fit, solid tension, and dependable durability. It installs cleanly without distortion, seats firmly in the groove, and holds the axle components securely in place even under aggressive riding. The steel quality feels noticeably stronger than many generic replacements, giving you confidence that it wont bend, stretch, or fail. If youre rebuilding your axle or replacing worn hardware, this snap ring is a reliable, affordable upgrade that keeps everything locked down the way it should be. Tusk nailed it with this one highly recommended for anyone who wants a no nonsense, high quality replacement part.
