The use of wheel spacers on an ATV is a subject with as many opinions as there are riders. There are numerous pros and cons. Spacers can be beneficial in some aspects, while in others, they can be detrimental.

A few years ago, when searching for a set of spacers for my Polaris Sportsman, I found the myriad of often contradicting information on the subject quite overwhelming.

To assist potential wheel spacer buyers in making an informed decision, I’ve consolidated all the possible pros and cons, as well as guidelines on when to use and when not to use them. Additionally, I’ve included some lessons from my own experience with them.

What Is the Purpose of ATV Wheel Spacers?

The primary purpose of wheel spacers is to alter the wheel spacing of the ATV, giving it a wider stance and better clearance inside the wheel wells.

You can get them in different thicknesses ranging from 1/2 to three inches. This means you can increase track width by up to six inches.

ATV wheel spacer thickness is measured in inches and ranges from 0,5 inches to two inches. Some even offer thicker spacers up to three-inch thicknesses.

Let’s look at various riding scenarios where you may need or benefit from having wheel spacers installed.

If you’ve already decided you need spacers, this post tells you how to choose and install them.

Pros of ATV Wheel Spacers

Better Clearance for Installing Tire Chains

Clearance issues when installing tire chains are a common reason for having to get wheel spacers. It was the main reason I had to get a set for my Polaris.

Most ATVs are not made to be used with tire chains. So when you install them, you may run into issues where the chains catch onto and damage various components of the ATV.

The front wheels are usually the most affected because they turn. Brake lines, inner fenders, or suspension parts may conflict with the chains.

You usually have more space at the rear wheels, and because they do not turn, you may apply the rule of thumb that says any clearance is proper clearance. But even at the rear, you may find the chains hitting your exhaust muffler or other components close to the wheel.

Adding a set of spacers should give you the clearance you need. You will likely need 1 to 2 inches thick spacers. I got the two-inch size for my Polaris, but 1,5 inches would probably be a better solution for this particular bike.

The best way to find out what size spacers you need is to install the chains with your stock wheels and measure how much clearance you’ll need. There is no exact science to this, but I recommend you aim for about one inch of clearance around the tire.

Better Stability on Steep Slopes or Rough Terrain

After the winter, I left my two-inch wheel spacers on the ATV just for fun (or rather out of laziness).

We often ride in areas with steep slopes. One plausible mishap when ascending such a hill is hitting a root, a bump, or a rock, causing the ATV to flip to one side and end up positioned sideways on the hill.

Without wheel spacers, it won’t be long until it flips and starts rolling down the hill. This happened to me, and for a second, I was sure that the ATV would start rolling.

But then I remembered I still had my wheel spacers, which ultimately saved me.

Another benefit is when you are doing some low-speed technical riding in really bumpy terrain. I do much of that too, and the increased stability (not so tippy) is quite noticeable.

With improved stability, you might find yourself tackling even bigger challenges, but I would advise against it.

So, to sum things up: a wider wheel stance will provide increased lateral stability when riding in hilly terrain, which might be beneficial in some of the more extreme riding situations.

Better Stability on Paved Roads

Where I live, you can legally use an ATV on public roads.

But when you ride at high speeds on paved roads, there is a risk that the ATV may flip due to the combination of excellent traction and narrow track width.

After installing spacers, I noticed that the ATV felt much more stable when riding turns.

The difference is not so noticeable when riding on gravel roads or trails. That’s because the lesser traction allows the ATV to slide sideways instead of flipping.

Most ATVs are designed to handle sharp turns on gravel roads without needing spacers to be stable. But it felt like they helped keep the ride steady on paved roads.

Increased Clearance When Installing Bigger Tires

When installing bigger and wider tires on your ATV, you may encounter many of the same rubbing issues when installing tire chains.

One way to solve this is by getting new rims with a different offset. But if you plan on using your old rims, you may need to add a set of spacers to prevent your new wheels from hitting various bike components.

It’s Cheaper Than Getting a Set of New Rimes

As mentioned above, getting a set of new rims with a different offset is one way to solve your problem when you run into clearance issues. Quality wheel spacers are not cheap but will still set you back less than most rims on the market.

Increased Safety

It is not hard to argue that better stability generally equals a safer ride. However, Spacers make the bike harder to turn, so it’s not all good. More on that later.

It Makes the ATV Look Better

The last one of the Pros comes down to personal preference. Some riders prefer the bike’s more aggressive look when widening the wheel stance.

Cons of ATV Wheel Spacers

There are a lot of benefits to installing wheel spacers on an ATV, but there are quite a few potential downsides as well. Ultimately you must decide whether you can accept some of the cons listed below.

You can minimalize most of them by choosing spacers that are only as thick as necessary but no more. Less is more when it comes to wheel spacers.

Increased Wear on Drivetrain and Suspension

Moving the tires further out from the axles will increase the strain on wheel bearings, ball joints, axles, and just about any component of the bike’s drivetrain and suspension.

The further you offset the wheels, the more significant momentum you get. This applies to both wheel spacers and different offset rims.

Therefore, it’s crucial to choose spacers that provide the extra clearance you need and no more. There are no added benefits to widening the bike beyond necessity, but the drawbacks will start to appear one by one.

The ATV Become Harder to Steer

The difference in steering geometry between stock and two-inch spacers is quite noticeable. Even bikes that have power steering may struggle to turn the wheels from time to time.

The reason why this happens is quite simple. When riding stock, the wheel’s center is aligned with the pivot point in the ball joints. When you turn, the wheel also pivots (rotate).

However, when you add spacers, you’re not just rotating the wheel but also moving it back and forth. Essentially, you’re forcing it to swing.

This extra movement puts much strain on the power steering system, which may cause premature wear or damage if you don’t pay attention. A bike without power steering will get heavier steering which may cause fatigue for the rider.

Increased Bump Steer (Bar Whip)

Bump steer is the twitch in the handlebar when you hit a rock or a small bump. Due to the same steering geometry changes described above, these twitches will become noticeably more powerful when you install spacers.

This adds to the strain on the power steering or the rider in a non-power steering ATV.

Expert Tip: Using wheel spacers only at the rear wheels will add a lot to stability without the downsides of changing the front wheels’ steering geometry.

The ATV May Become Too Wide for Some Trails

With a wider stance, your ATV may not fit as well into the ruts on muddy trails where others ride with stock configurations. Your wheels will brush off on track edges and rocks where others pass through. It will become harder to ride, and you risk damaging your wheels.

Some trails are set with a maximum legal width of 50 inches. Adding wheel spacers may make your ATV illegal to use on such trails.

ATV May No Longer Fit Between Trees or Through Narrow Passages

The extra width may be enough so you don’t fit between when riding in dense forests, through narrow gates, or between narrow rock passes.

They Will Likely Make You Dirty

When installing wheel spacers, your stock fenders may no longer protect you from flying mud and dirt.

Stock wheels on most ATVs are about in-line with the fenders. When you install wheel spacers, you will quickly learn that this design feature did not happen accidentally.

Expect to get dirty or pay for a set of fender-flares that widens your fenders and increases their coverage.

The ATV Will No Longer Fit All Truck Beds and Trailers

Ensure your trailer or truck bed is wide enough for a wider ATV. This aspect is sometimes overlooked when people install wheel spacers. Measure twice, buy once!
