We enjoy driving the ATV, and this has caused the popularity of the sport. It is an exciting sport, but all the same, disgust when you find some of its axles not functioning effectively.

With your ATK’s axle failure, you have no other option other than planning to replace it.  Do you even know where to buy them? I guess not! And perhaps I am right.

However, that should not worry you. We have prepared a list of the best aftermarket ATV axles for you.

Best Aftermarket ATV Axles

Many of the axles on the market are heavy-duty made from some renowned engineering companies in America.

So what does this tell you?

You are sure of the quality and safety of what you buy through our recommendation.

However, before we recommend anything to you, we would like to arm you with information that will take you a long way in buying the best axles for your ATV.

How To Choose The Best Aftermarket ATV  

If you can approach experienced ATV users, they would so comfortably tell you that not all Aftermarket ATV axles are best for your ATV. While you are in a hurry to replace your ATV axles, it is essential to consider the following factors: they help you choose the best aftermarket ATV axles.

  1. Construction

The condition under which ATV drives is challenging terrain compared to streetcars. Although China uses the same standard as the streetcar when making the axles, the strength required is more. The manufacturing companies use 5140 alloy steel, which is cheap but with high heat technology and excellent performance. Consider checking for this material, as it has proven to heat resistible for driving elements like axles.

  1. Heat treatment

The 5140 alloy steel is good enough but not the best until it is heat-treated. The axles are heat treated through a process known as normalizing. It helps in strengthening the axles towards achieving the country standard.

  1. Size

The OE parts used to be strong enough for a regular drive and not making it in rock crawling and mud race parts in the past. However, aftermarket products are made more prolonged and more extensive to meet the extended suspension and strength.  A shaft usually has a diameter of about 20 % increased following the working space and angle limit.

  1. Grease

Constant velocity joint is a requirement while recognizing that the high temperature and pressure reduce excessive wear and prolong the joint’s life. With several grades and different grease in the market, some apply the same levels as cars. In contrast, others like heavy-duty ATV axles use high-grade grease to ensure long lusting and prolonged life of the constant velocity joints.

  1. Profile

One of the factors that determine the strength of an axle is profile. The design of the OE replacement parts should be smooth to avoid stress rise. However, with an experienced engineer, it is never an issue. When you decide to have a customized axle, recall reminding them about the profile.

  1. CV Boot

CV boot is responsible for enclosing and preventing dust and sand particles from getting into the lubrication system. It is a requirement for the boot to have high-temperature resistance, and the material that gives it this ability is TPEE. TPEE has excellent low fatigue resistance, oil resistance, and a long-term erosion of wide working temperature. It is crucial to check on the boot to ensure that the relevant materials are included for effective working.

 What are the Best Aftermarket ATV Axles

Knowing what we should look for when buying ATV axles, let us now jump to some of the best axles for our ATV.

Frequently Asked Questions

Question: How Is An ATV Axle Measured?

Answer: Firstly, make sure you extend the axle to the maximum point possible by pulling on both ends. Secondly, from the outside of each end, cup face to get your extended measurements. Then push the CV’s together to the maximum point possible and measure again. In addition, this is your compressed measurements.

The compressed and the extended measurements are among the specifications designers and engineers used to measure the length of an axle. To determine the axle you need to use these specifications.

Question: What Type of Axle Allows Easier And Smooth Turns An ATV?

Answer: A differential axle. It lets the outside wheel rotate faster than the inside wheel, resulting in a more comfortable and smoother turn.

Question: How Do You Remove Your ATV Axles?

1. Take your ATV into the pack and raise your machine using a jerk so that the front wheels are off the ground.
2. Using a screw remove the nuts and pull the wheel of the machine.
3. Take back the nut but lightly tightened so that they are not lost.
4. In case your axle nut has caps, remove them, then remove the nuts using nose pliers. To remove the nut, you may need someone pressing and holding brakes to have the required resistance.
5. Remove the brake caliper followed by the fasteners. You can either disconnect the brake hose or leave it like that. However, master the route of the brake so you can take it back the same way.
6. Remove the hub
7. Free up the axle from its attachment by removing the tie rod end from the spindle. While steering the knuckle joint, swinging the carrier assembly down and back, remove the upper steering knuckle joint from the bearing carrier.
8. Assuming your axle is free, now it is time to pull the axle out of the casing. Pull it from a right angle and ensure your ATV will not fall off the jack. Hold on to the shaft while doing some swift tugs. You may need to push it inward first to make sure that the snap ring usually found in, is not preventing it from coming out.
9. In case you find it stuck, spray the casing area using a lubricant and give it a few minutes and then thereafter, you should be able to remove it.

Question: How Do I Know if My ATV Axles Are Bad?

Answer: For you to prove that your axle is bad, try to figure out the following symptoms:
A buzzing sound
Although a buzzing sound may result from inadequate grease, it can also be the sound of a bad wheel.
If you hear the sound of a cluck when you accelerate, slow down, or shift gear
To be sure about this, put the ATV in reverse mode, and then vary it up and down. If the noise gets louder, then you ought to replace your axle.
Hearing a popping or clicking noise when turning
To confirm this, put your machine in reserve mode, switch all the handlebars one way, drive in a circle, and the axle is bad if the noise gets louder.
Vibration on Acceleration
Although the inner or outer joints’ movement can cause this, it is usually an indication of a worn-out inner joint.


Despite the above-listed axles being the best, there is one category that I like and prefer most. Rhino brand axles are made to operate at high angles and resist the abuse that comes with including a lift kit and extra tires to your machine. Rhino has established an excellent reputation with its high quality and well-performing axles.

The rhino axles’ price ranges from $149- $209 and a warranty for two months. If the axle breaks within two months, the manufacturer replaces it at no cost. If the axle fails after the two months but within the first year of buying, it is still replaced, but now the buyer pays a $50 fee and shipping for both ways, but boots are not covered.
