7 Best X Chocks for RV (Researched and Compared)

X chocks are a popular choice for RV owners looking to minimize side-to-side rocking and improve stability when parked. Unlike standard wheel chocks, X chocks fit between tandem wheels and use a scissor mechanism to apply outward pressure, effectively locking both wheels in place. After researching manufacturer specifications, industry safety standards, and aggregated owner feedback, we compared seven top models to help you find the best X chocks for your RV. Our evaluation focuses on real-world performance, build quality, and value.

1. Camco Adjustable X Chock (56604): Best Overall

🛒  Check Price on Amazon →

The Camco Adjustable X Chock is the most popular model on the market, and for good reason. Its adjustable design fits wheel gaps from 3.5 to 5.5 inches, covering the vast majority of tandem-axle RVs. The all-steel frame and rubber contact pads provide a secure grip without marring your wheels. Based on owner feedback, installation is straightforward and the chock effectively reduces rocking. In our evaluation, we found the balance of adjustability and build quality to be excellent for most RV owners.

However, the hardware is prone to surface rust if exposed to road salt or frequent rain, so occasional maintenance is needed. This chock may not be ideal for full-time boondockers in harsh climates who need maximum corrosion resistance. For the typical weekend traveler, it offers the best combination of performance and value.

• Adjustable width fits most tandem wheel setups
• Rubber pads protect wheel finish and improve grip
• Easy to install with integrated handle

Pros: Versatile fit across many RV models; Solid steel build with powder coat finish
Cons: Some users report rust on hardware after prolonged wet use

2. TorkLift Stabilizer X Chock (TL-2628): Most Durable

🛒  Check Price on Amazon →

The TorkLift Stabilizer X Chock is built for owners who prioritize long-term durability. Its zinc-plated steel construction and thick rubber pads outperform painted alternatives in resisting rust and wear. In our research, owner reviews consistently praise its robust feel and ability to stay tight even on uneven ground. The chock fits wheel gaps from 3 to 5 inches, making it ideal for many travel trailers and fifth wheels.

The trade-off is a slightly narrower adjustment range, so it may not work on RVs with unusually wide wheel spacing. Also, the compact design can be a bit harder to turn by hand if the threads are dirty. If you live in a wet or salty environment, this is the best choice for longevity.

• Zinc-plated steel resists corrosion better than painted models
• Thick rubber pads provide excellent traction
• Compact design fits tighter wheel gaps

Pros: Superior corrosion resistance for long life; Very sturdy with no flex under load
Cons: Adjustment range is narrower than some competitors

3. Lippert Components SolidStep X Chock: Best Value

🛒  Check Price on Amazon →

The Lippert SolidStep X Chock offers a solid balance of cost and performance. It fits wheel gaps from 4 to 5.5 inches and uses steel construction with a black powder coat finish. Owners report that it effectively reduces rocking and is easy to install. For those on a budget, it provides reliable stability without breaking the bank.

However, the powder coat is less durable than plated finishes, and some users note chipping after a season of use, which can lead to surface rust. This chock is best for casual RVers who store their rig indoors or in dry climates. If you expect heavy use in wet conditions, consider spending more on a corrosion-resistant model.

• Budget-friendly without major compromises
• Wide rubber pads for good contact
• Easy to adjust with T-handle

Pros: Affordable price point; Works well on standard tandem axles
Cons: Paint can chip over time, leading to rust

4. BAL X-Chock (28050): Easiest to Install

🛒  Check Price on Amazon →

The BAL X-Chock is designed for convenience. Its quick-turn handle allows you to install and remove it faster than most competitors. The zinc-plated steel offers decent rust protection, and the lightweight build makes it easy to handle. For RVers who move frequently, this chock saves time and effort.

However, the fit range is limited to 4.5-5.5 inches, so it won’t work on RVs with tighter wheel gaps. Additionally, the rubber pads are smaller than some, and a few owners mention that the chock can slip on very smooth surfaces. It’s a great choice for those with compatible wheel spacing who prioritize speed.

• Quick-turn handle for fast installation
• Zinc plating provides moderate corrosion resistance
• Lightweight design

Pros: Very easy to adjust and remove; Good for frequent setup and takedown
Cons: Narrow fit range may not work on all RVs; Some users report slipping on smooth concrete

5. Ultra-Fab Products X-Chock (UF20-941011): Heavy Duty Pick

🛒  Check Price on Amazon →

The Ultra-Fab X-Chock is built for heavy-duty applications. Its welded steel frame and large rubber pads provide a strong, secure hold for larger RVs. Owners of big fifth wheels appreciate the stability it offers, even on uneven terrain. In our evaluation, the construction feels very solid.

However, this chock is noticeably heavier and bulkier than others, making it less convenient for quick setups. The painted finish is prone to chipping and rust if not cared for. It’s best suited for RVers with heavy rigs who don’t mind the extra weight and want maximum strength.

• Welded steel frame for extra strength
• Large rubber pads for secure grip
• Designed for larger RVs and heavy use

Pros: Very robust build; Good for heavy fifth wheels
Cons: Heavy and cumbersome to handle; Painted finish can rust if scratched

6. Dexter DX Series X Chock (K71-651-00): Compact Fit

🛒  Check Price on Amazon →

The Dexter DX Series X Chock is designed for RVs with narrow wheel gaps, typically 3 to 4 inches. Its compact size makes it easy to store and handle. Owners of smaller travel trailers and pop-up campers find it effective for reducing wobble.

However, the narrow fit range means it won’t work on most standard tandem axles. The all-painted steel construction is less durable than plated options, and some users report bending under heavy loads. This chock is a good choice only if your wheel gap is on the smaller side.

• Narrow fit for tight wheel gaps
• Compact and lightweight
• Simple scissor mechanism

Pros: Works well on small trailers with narrow gaps; Easy to store
Cons: Limited adjustability; Not as durable as larger models

7. Valterra EZ-X Chock (VX-1000): Lightweight Option

🛒  Check Price on Amazon →

The Valterra EZ-X Chock stands out for its lightweight aluminum build. It’s easy to carry and install, making it a favorite for RVers who prioritize portability. The aluminum won’t rust, which is a plus in wet climates.

However, the aluminum is less rigid than steel, and some owners note that the chock can flex or even bend when used on heavier RVs. It also has a smaller rubber contact area, which may reduce grip on slick surfaces. This chock is best for lightweight trailers or as a secondary stabilizer, not for heavy fifth wheels.

• Aluminum construction resists rust
• Very lightweight at under 2 lbs
• Ergonomic handle for easy adjustment

Pros: Lightest option for easy carrying; No rust concerns
Cons: Less durable than steel models; Some owners report flex under heavy load

Frequently Asked Questions

What is an X chock and how does it differ from a regular wheel chock?

An X chock is designed to fit between two tandem wheels on an RV. It uses a scissor mechanism to apply outward pressure against both tires, reducing side-to-side rocking. Regular wheel chocks only block forward/backward movement and are placed against the front or back of a single tire. X chocks provide additional stability for parked RVs.

Can X chocks be used on single-axle trailers?

No, X chocks are specifically designed for tandem (dual) axle setups. They require two wheels side by side to wedge between. For single-axle trailers, use standard wheel chocks or other stabilizing products.

How do I know which size X chock to buy?

Measure the gap between your two tandem tires when the RV is parked on level ground. Most X chocks specify a range (e.g., 3.5 to 5.5 inches). Choose a chock whose range includes your measured gap. Also consider the tire diameter and weight of your RV for load capacity.

Are X chocks safe for use on all surfaces?

X chocks work best on firm, level surfaces like concrete or asphalt. On soft ground (gravel, dirt), they may sink or shift. Some models have rubber pads that improve grip, but for soft surfaces, consider using a base plate or additional chocks. Always follow the manufacturer’s safety guidelines.

Do I need X chocks if I already have leveling jacks?

Leveling jacks primarily stabilize the RV vertically and front-to-back. X chocks reduce side-to-side movement (rocking) caused by wind or movement inside the RV. They complement jacks and are especially useful for RVs with tandem axles. Many owners use both for maximum stability.
