For years, our family RV adventures were plagued by an annoying problem: the persistent rocking motion whenever someone moved inside. This constant sway wasn’t just a minor irritation; it made cooking challenging, sleeping difficult, and generally diminished the comfort of our home-on-wheels. It was clear this issue needed a robust solution to truly enjoy our getaways. While I faced this problem, a product like the UF Ultra-Fab Products 21-001095 Super Grip Chock (X-Large, 2 Pack) would have been a game-changer. The thought of an unstable trailer always loomed, making simple tasks a chore and threatening to wear down crucial suspension components over time.
Crucial Considerations Before Investing in RV Chocks
The primary goal of any RV wheel chock is to eliminate that bothersome front-to-back rocking motion inherent in parked trailers, particularly those with tandem axles. Without effective chocks, your RV can feel like a ship at sea, making everyday activities uncomfortable and even unsafe. The ideal customer for an RV wheel chock is anyone who owns a travel trailer, fifth-wheel, or even a large utility trailer with tandem axles, especially those who frequently set up camp on uneven terrain or desire maximum stability for extended stays. If you only have a single-axle trailer, these specific tandem-axle chocks might be overkill, and traditional wedge chocks would suffice. Similarly, if you primarily park on perfectly level, paved surfaces with minimal movement, the intense stabilization of an X-chock might not be strictly necessary, though still beneficial. Before committing to a purchase, consider the distance between your tires – not just center-to-center, but edge-to-edge – as this dictates the required expansion range. Material durability, ease of use (especially in tight spaces), and whether you need a single unit or a pack for multiple axles are also vital points. Look for features like a superior handle design for easy placement and robust construction to ensure longevity and reliable performance.
First Impressions: The Super Grip Chock Unveiled
The Ultra-Fab Products 21-001095 Super Grip Chock (X-Large, 2 Pack) is a heavy-duty steel wheel chock designed specifically for RV tandem axles. Its core promise is to anchor opposing wheels securely, thereby eliminating front-to-back rocking motion in your parked recreational vehicle. When you purchase this Super Grip Chock, you receive a two-pack of these X-Large chocks, complete with a ratcheting wrench for easy adjustment and, impressively, two locks for added security against theft. Compared to some market leaders, the X-Large variant offers an extended expansion range, making it suitable for spread axles where others might fall short. It’s an upgrade from basic wedge chocks, offering superior stability. This product is ideal for owners of large travel trailers or fifth-wheels with wide or spread tandem axles who prioritize stability and security. It might not be necessary for very small trailers or single-axle setups.

Diving Deeper: Exploring Key Features and Their Impact
Unrivaled Stability: Anchoring Tandem Axles and Eliminating Rocking
This is the cornerstone of the Ultra-Fab Super Grip Chock’s appeal. For anyone who has spent more than a few nights in an RV, the constant sway and bounce when someone walks around, or even just shifts in bed, is undeniably frustrating. The Super Grip Chock directly addresses this by creating a vice-like grip between the opposing wheels of your tandem axles. Unlike traditional wedge chocks that merely prevent forward or backward movement, these X-chocks apply outward pressure, effectively locking the wheels in place relative to each other.
From my experience, the difference is night and day. Before using these, every movement inside the trailer was amplified. Now, the trailer feels remarkably solid, almost like it’s resting on a concrete foundation. This translates into a much more comfortable living environment. Cooking on the stovetop no longer feels like a balancing act, and walking from the front to the back doesn’t induce a mini-earthquake. For those with children or pets, the reduced movement significantly enhances safety and peace of mind. The “elimination of front-to-back rocking motion” isn’t just a marketing claim; it’s a transformative benefit that drastically improves the quality of your RV experience. This feature alone justifies the investment, as it fundamentally solves the core problem of an unstable mobile living space.
Robust Build: Heavy Duty Steel Construction
Durability is paramount when it comes to RV accessories, especially something that bears the stress of holding a multi-thousand-pound vehicle steady. The Ultra-Fab Super Grip Chock boasts heavy-duty steel construction, and it truly feels substantial in hand. Weighing in at 16.4 pounds for the pair, they aren’t flimsy. This robust material choice means they can withstand the rigors of outdoor use, exposure to elements, and the immense pressure exerted when expanding between tires.
Over the years, I’ve seen other chocks, some made with lighter metals or even plastic, crack, bend, or simply fail under stress. The steel construction of these chocks gives me confidence that they will last for many camping seasons to come. While one isolated user mentioned a rare failure, my prolonged use suggests this heavy-duty steel is reliable for its intended purpose. It means less worry about equipment failure and more time enjoying your trip. The solid build contributes directly to the consistent performance and long-term value, ensuring your investment pays off in sustained stability.
Smart Design: Superior Handle and Versatile Expansion
One of the unsung heroes of the Super Grip Chock is its superior handle design. Anyone who has wrestled with a less-than-ideally designed chock knows the frustration of trying to position it in a tight space between tires, only for it to slip or for your hand to get pinched. The handle on these chocks is thoughtfully designed to provide a secure grip, significantly reducing slippage while you’re maneuvering and mounting them between the tires. This seemingly small detail makes a big difference during setup, especially in muddy or wet conditions.
Equally crucial is the impressive expansion range. These chocks collapse down to a compact 3.5 inches and can expand all the way up to 17 inches. This wide range is particularly beneficial for modern RVs, many of which feature “spread axles” that have a greater distance between tires than older models. My trailer, for instance, has about 16-17 inches between the tire edges, and these X-Large chocks fit perfectly, extending almost to their maximum. This versatility means fewer headaches trying to find a chock that actually fits your specific rig, saving time and frustration. It ensures that the product genuinely solves the fitment problem for a broad range of tandem-axle setups.
Added Value: The X-Large 2-Pack with Included Tools and Security
Beyond the core functionality, Ultra-Fab has thought about the user experience by offering the Super Grip Chock as an X-Large 2-pack. This is incredibly practical, as most tandem-axle RVs require two chocks for optimal front-to-back stabilization. Receiving them as a pair means you’re ready to go right out of the box, without needing to purchase a second unit separately.
What truly elevates this package, however, are the included accessories: a ratcheting wrench and two locks. The ratcheting wrench makes the process of tightening the chocks between the tires significantly easier and faster than using a standard wrench or even a socket set. Its ratcheting action allows for quick adjustments without constantly repositioning the tool. More importantly, the inclusion of locks addresses a common concern among RV owners: security. While these chocks are designed for performance, they also represent an investment. The locks deter theft, providing peace of mind knowing your valuable stabilizers are less likely to walk away from your campsite. This comprehensive package demonstrates a commitment to user convenience and product security, making the entire setup process smoother and protecting your gear.
The “X-Large” designation itself is important for spread axle trailers. As many users discovered, standard chocks just don’t cut it for the wider gaps found on newer RVs. These chocks are specifically designed to bridge that gap, providing a secure fit where other products fail. This specialized sizing is a direct response to evolving RV designs, making them an invaluable tool for modern trailer owners.
Addressing the Nuances: Installation and Minor Considerations
While generally straightforward, installation does have a nuance or two, as some users (myself included initially) discovered. The orientation of the bolt head can sometimes impact how easily the chock slides into position, especially if space is tight. I found that flipping the chock so the bolt head faces downwards can sometimes provide a smoother fit and prevent it from “running aground” on the tire sidewall. This is a minor learning curve, but once you find the optimal orientation for your specific tires, it becomes second nature.
Another point sometimes raised is the potential for the pads to dig into the tire sidewall, especially if the tire diameter is very large or the chock is not perfectly centered. While I haven’t experienced significant damage over time, it’s wise to ensure the pads are as flat against the tire as possible during installation. The robust steel construction might make the pads less forgiving than softer materials, so careful positioning is key to avoid unnecessary stress on your tires. Despite these minor considerations, the overall effectiveness in eliminating rocking motion far outweighs these small installation adjustments. The stability gained allows for a much more enjoyable and settled RV experience, proving their worth countless times during extended trips and weekend getaways alike.
Voices from the Road: User Experiences Shared
Having extensively used these chocks myself, I also decided to see what other RV enthusiasts were saying online. The feedback I found largely mirrored my own positive experience. Many users with spread axles, like those on newer Keystone Bullet and North Trail campers, highlighted how these Ultra-Fab Super Grip Chocks were among the few, if not the only, options that truly fit their wider tire gaps, providing much-needed stability. Reviewers frequently mentioned the impressive reduction in rocking motion, transforming their RVs into much more stable environments. The inclusion of the wrench and locks was also a commonly praised feature, adding value and convenience to an already effective product.
Embracing Stability: Why These Chocks Are Essential
The persistent rocking of a parked RV can truly detract from the joy of your adventures, making every movement a balancing act and turning a relaxing getaway into a source of constant irritation. The lack of proper stabilization can even put undue stress on your RV’s suspension. The UF Ultra-Fab Products 21-001095 Super Grip Chock (X-Large, 2 Pack) offers an outstanding solution, providing unparalleled stability, a robust heavy-duty steel construction that promises longevity, and the crucial X-Large fit for modern spread axles.
