6 Best Adjustable Wheel Chocks For Different Tire Sizes Nomads Swear By

That slight, unnerving wiggle you feel every time someone walks to the back of the trailer is more than just an annoyance; it’s a constant reminder that your rolling home isn’t quite settled. While traditional wedge chocks stop you from rolling away, they do almost nothing to combat the fore-and-aft rocking that turns a simple movement into a rig-wide event. This is where adjustable, between-the-tire wheel chocks come in, transforming a shaky trailer into a stable, grounded living space.

Choosing Chocks for Stability and Peace of Mind

The fundamental job of an adjustable chock is to apply opposing force between the tires on a tandem or triple-axle setup. This effectively locks the suspension in place, eliminating the bounce and jiggle that comes from the tires shifting on their axles. It’s the difference between feeling like you’re on a boat and feeling like you’re in a foundation-built home.

Before you buy anything, grab a tape measure. The single most important factor is the distance between your tires. This gap determines which models will even work for your rig. Some chocks are designed for tight, standard axle spacing, while others are built specifically for the wider stances found on many modern trailers.

Don’t just think about fit; think about your workflow. Are you a weekend warrior who sets up once, or a full-time nomad who moves every few days? A chock that requires five minutes of cranking with a ratchet might be fine for a long stay, but it will feel like a chore if you’re constantly on the go. Your camping style should guide your choice just as much as your axle spacing.

BAL X-Chock: The Original Tandem Axle Stabilizer

When people talk about this style of chock, the BAL X-Chock is usually what they picture. It’s the original, a time-tested design that has been stabilizing RVs for decades. Its simple scissor-action mechanism expands between the tires, and a few turns of the included ratchet wrench locks everything down tight.

The standard X-Chock is designed to work on tire spacings from 1-3/8 inches up to 10 inches. This covers the vast majority of tandem-axle travel trailers and fifth wheels on the road. Made of heavy-gauge steel with a corrosion-resistant coating, these things are built to last. You’ll see them in campgrounds everywhere for a reason: they just work.

The key thing to remember is that the X-Chock is a stabilizer, not a primary chock. BAL explicitly states you should still use traditional wedge chocks to prevent rolling before installing the X-Chock. It excels at one job—eliminating movement—and it does that job exceptionally well. For pure, dedicated stabilization, it remains the gold standard.

Andersen Leveler: Leveling and Chocking in One

The Andersen Leveler breaks the mold by combining two of the most tedious setup tasks into one simple action. Instead of messing with stacks of leveling blocks and separate wheel chocks, you get a single, integrated system. It’s a brilliant piece of engineering for anyone who values speed and simplicity.

The system consists of a curved, crescent-shaped ramp and a matching chock wedge. You simply place the ramp in front of or behind the tire on the low side of your rig and drive up until you’re level. Then, you slide the chock wedge under the ramp, and you’re done. You’ve leveled and chocked one side in a single, fluid motion.

While incredibly efficient, it’s a different approach. You are primarily chocking one tire very, very securely. For most rigs, this is more than enough to prevent movement, but some people still prefer to add a traditional chock on the opposite side for redundancy. Made from a surprisingly durable polymer, these things can handle immense weight, but their real value is in turning a 15-minute setup chore into a 30-second task.

Camco Tandem Chock: A Reliable, User-Friendly Pick

Think of the Camco Tandem Chock as a highly effective and often more affordable alternative to the big-name brands. It performs the same essential function as the BAL X-Chock, using a threaded screw to expand a scissor mechanism between your tandem tires. It’s a straightforward design that gets the job done without any fuss.

This chock is designed for tire spacings from 3 inches to 10 inches, a slightly different range than the standard X-Chock. This small difference can be crucial, so it’s another reminder to measure your specific rig. It’s a solid, all-metal tool that provides a dramatic reduction in trailer movement once installed.

Where the Camco often shines is in the small details. Some versions include an easy-start nut that makes getting the threads engaged much quicker. For RVers who want proven stabilization technology without paying for a brand name, the Camco is a workhorse that offers fantastic value.

Fastway ONEstep: The Quickest Chock on the Block

If you’re an overnighter or someone who hates a long setup and teardown process, the Fastway ONEstep was made for you. This chock is all about speed. It completely eliminates the need for a ratchet wrench or any hand-cranking, replacing it with a simple, foot-operated lever.

The design is ingenious. You place the chock between the tires, and a single push down with your foot expands the scissor arms and locks them into place. Removal is just as fast. This can save you precious minutes every time you park, which really adds up on a long journey with multiple stops.

The tradeoff for this speed is a bit less adjustability. The ONEstep is designed for specific axle spacings (typically 16" to 24" center-to-center), so you need to ensure it matches your trailer. But if you’re in that range, there is simply no faster way to get your rig stabilized. It’s a game-changer for nomads who prioritize efficiency above all else.

Ultra-Fab Super Grip: Heavy-Duty Locking Power

For owners of larger, heavier rigs, even small movements can feel significant. The Ultra-Fab Super Grip Chock is engineered for maximum holding power. It’s a heavy-duty option that provides an incredibly solid, locked-in feel, inspiring confidence when you’re parked.

The design often features wider, contoured louvers on the pads that contact the tires. This creates more surface area and allows the chock to bite into the tire treads for a superior grip, preventing even the slightest shift. The robust steel construction is built to handle the forces exerted by big fifth wheels and toy haulers.

A standout feature on some Ultra-Fab models is a built-in locking mechanism. A simple hole allows you to slip a padlock through the chock, which not only secures it from theft but also adds a layer of theft deterrence for your entire trailer. It’s a small detail that provides significant peace of mind.

BAL X-Chock Extended for Wide-Spaced Axles

You measured the gap between your tires and it’s 12 inches. A standard X-Chock won’t work; it maxes out at 10 inches. This is a common scenario with many newer trailers that use wider axle stances for improved towing dynamics, and it’s exactly why the BAL X-Chock Extended exists.

This model operates identically to the classic X-Chock but is built on a larger scale. It’s designed to cover gaps from 10 inches all the way up to 17 inches, bridging the gap where standard models fall short. It provides the same rock-solid stabilization, just for a different geometry.

This product is the perfect lesson in the "measure twice, buy once" philosophy. Many nomads have bought a standard chock only to find it’s useless for their rig. Knowing your trailer’s specific dimensions is not optional. If you have a wide-stance axle system, the extended version isn’t just a good option; it’s your only option for this style of chock.

Matching Your Chock to Your Axle and Tire Size

There is no single "best" chock, only the best chock for your trailer and your style of travel. Don’t get swayed by what someone else uses; focus on what your setup requires. Making the right choice comes down to a few simple steps.

First and foremost, measure the gap between your tires. This one measurement will immediately narrow your options and prevent you from buying a tool that simply won’t fit. Write it down and compare it to the operating range of any chock you consider.

Next, honestly evaluate your needs and priorities with a simple framework:

• For Maximum Speed: If you move often and hate setup time, the Fastway ONEstep is in a class of its own.
• For All-in-One Leveling: If you want to simplify your entire process, the Andersen Leveler is a brilliant multi-tasker.
• For Classic, Proven Stability: For most standard tandem axles, the BAL X-Chock or the Camco Tandem Chock are reliable, powerful choices.
• For Heavy Rigs & Security: If you have a large rig or want added theft deterrence, look to the Ultra-Fab Super Grip.
• For Wide-Stance Axles: If your tire gap is over 10 inches, the BAL X-Chock Extended is the purpose-built solution.

Ultimately, the goal is to make your RV feel less like a vehicle and more like a home. By matching the right tool to your specific rig, you eliminate one of the biggest annoyances of mobile living and gain a much more comfortable, stable foundation for your adventures.

Investing in the right adjustable wheel chock is one of the highest-impact upgrades you can make for your quality of life on the road. It’s a small change that transforms your daily experience, turning a shaky trailer into a solid, peaceful sanctuary, no matter where you decide to park it.
