Buyer's Guide for UTV Axles: Helping You Shop!

When to Replace vs. When to Upgrade Your UTV Axles

Not every axle job requires an expensive upgrade. Sometimes, a quality OEM-replacement axle is exactly what you need to get back on the trail with as little hassle as possible. If your stock axle failed due to normal wear after years of moderate use, and you're not planning any major modifications, a direct replacement axle restores your machine to proper working order at a reasonable cost. These are ideal for work UTVs where downtime is expensive, and you just need reliable transportation without paying for performance you won't use.

However, there is one often overlooked factor: if you've already broken multiple stock axles, the smart financial move is upgrading rather than continuing to replace. A $400 heavy-duty axle that lasts five years beats buying three $200 stock replacements over the same period, plus you eliminate the frustration and inconvenience of repeated failures.

How Aftermarket UTV Axles Set Themselves Apart

There are several key differences between stock and premium upgrade axles that you’ll want to familiarize yourself with if you’re going to get the most utility per dollar. For example, where stock axles will typically use more basic CV joints and rubber boots sealed with simple clamps, performance-grade replacements will use chromoly steel, which is much (much) stronger.

Shaft diameter is also no small matter when upgrading axles. Increasing your diameter by 5 mm or more will dramatically increase your axle’s resistance against torque and other strong forces translating up from the ground. Finally, boot material is an often overlooked factor. High-quality axles are reinforced with materials like neoprene or thermoplastic.

How Your Setup Should Influence UTV Axle Choice

Taking your current setup into account when replacing your stock axle will help you find the perfect fit. If you’re looking to keep running stock tires, for example, a straight stock replacement axle might be the play. However, if you’re looking to run some chunkier tires and/or lift your machine, heavy-duty axles may be the best option. These come with more robust shaft diameters and fortified CV joints to hold up against more serious abuse.

When you need an aftermarket UTV axle that can withstand even tougher abuse, then you might be in the extreme-duty or porta-rated axle category. These things are engineered for the toughest use cases, including running a portal gear lift, 35+ inch tires, a supercharged engine or other performance mods. Rhino and SuperATV are among two of the most trusted names when it comes to extreme-duty side-by-side axles. If you’re going extreme, then no other type of axle will cut it!

UTV Axle Frequently Asked Questions

How can I tell when my axle is failing?

The quintessential indicator of an axle in trouble is a clicking or popping noise that can be heard while you’re turning. This sign and other similar issues (like vibrations while speeding up) may indicate that it’s time for a new axle.

Do I have to swap both axles out at the same time?

Axles are one of those components that you don’t have to worry about changing out all at once. Just keep in mind that one failed axle (due to regular wear) may mean the other one is also on its way out.

Will I need to make any tweaks before installing a new axle?

That depends on the axle. While there are plenty of bolt-on replacement UTV axles out there (ah, how we love them), you are much more likely to need modifications if you’re installing axles as part of a lift kit or portal gear hookup. Always research the modifications and hardware you will need ahead of time.
