1. Camco 58141 Yellow Jack Leveling Block: Best for Light Trailers
The Camco 58141 Yellow Jack Leveling Block set is a popular choice for smaller trailers and campers. In our evaluation based on owner feedback, these polymer blocks are lightweight and easy to stack to the desired height. The interlocking tabs keep them together, and the textured top provides decent grip. However, the 5000-pound capacity per pair (when used as a pair) means they are best suited for single-axle or lightweight tandem trailers. Some owners reported that the blocks can crack under heavy loads or if driven over accidentally.
If you have a large travel trailer or a fifth-wheel, we suggest looking at heavier-duty options. These blocks are ideal for pop-up campers, small utility trailers, or as a secondary leveling aid. They are not designed to support the full tongue weight of a heavy trailer for extended periods.
- Set of 10 interlocking blocks allows custom height up to 10 inches
- Lightweight and easy to store, each block weighs under 1 pound
- Textured surface helps prevent jack slippage
Pros: Very affordable for a set of 10; Interlocking design lets you adjust height precisely
Cons: Not recommended for heavy fifth-wheel or large travel trailers
2. Andersen Hitches 3604 Jack Block: Best Heavy-Duty
The Andersen Hitches 3604 Jack Block is a heavy-duty solution we found to be among the most stable options. In our research, its high-density polyethylene construction with a molded-in steel plate gives it a very high weight capacity and prevents it from sinking into dirt or gravel. Owners consistently praise its stability and lack of movement under load. The non-skid top keeps the jack foot in place. However, it offers no height adjustment, so it is best used on level ground or combined with other blocks.
If you need adjustable height or have a lightweight trailer, this block may be overkill. It is also relatively heavy at around 5 pounds, which may be a consideration for some. But for those with large travel trailers or fifth-wheels, this is a top contender for safety and durability.
- Integrated steel plate prevents sinking into soft ground
- Non-skid surface and large footprint for stability
- Works with most trailer jacks up to 10,000 lbs tongue weight
Pros: Extremely durable and can handle heavy trailers; Steel plate provides excellent ground support
Cons: Heavier and bulkier than polymer blocks; Only one height (3.5 inches) with no adjustment
3. TorkLift 2820 FastJack Trailer Jack Block: Best Adjustable Height
The TorkLift 2820 FastJack offers a unique adjustable height feature that we found very convenient. Based on owner feedback, the twist-lock mechanism allows you to quickly set the height from 1.5 to 6 inches, making it flexible for different ground conditions. The aluminum base is sturdy and resists corrosion. However, its 6,000-pound capacity is lower than some heavy-duty blocks, so it is not recommended for the largest trailers. Some users reported that the locking mechanism can slip if not fully tightened.
If you have a medium-sized travel trailer or a boat trailer and want a single block that adapts to uneven ground, this is a great choice. But for very heavy loads or long-term storage, a fixed block may be more reliable.
- Adjustable height from 1.5 to 6 inches via a twist-lock mechanism
- Aluminum base plate resists rust and corrosion
- Quick and easy to set up without tools
Pros: Height adjustable eliminates the need for stacking blocks; Compact when collapsed for storage
Cons: Lower weight capacity than some fixed blocks; Twist-lock mechanism may loosen over time if not maintained
4. Valterra EZ Level Trailer Jack Block: Best Value
The Valterra EZ Level block is an economical option we evaluated for budget-conscious buyers. Made from recycled rubber, it provides a decent non-slip surface and can be stacked with other blocks. However, its 4,000-pound capacity means it is only suitable for small trailers, pop-ups, or as a secondary block. Some owners noted that the rubber can become brittle after prolonged UV exposure.
If you have a heavy trailer or need a block for frequent use, we recommend investing in a more durable material. This block is best for occasional use with lightweight trailers and for those who want to minimize environmental impact.
- Made from recycled rubber, environmentally friendly
- Non-slip surface on both sides
- Can be used as a single block or stacked with others
Pros: Very low price point; Eco-friendly material
Cons: Lower weight capacity limits use to lighter trailers; Rubber can degrade in extreme sun or cold
5. Lippert Components 284676 Solid Jack Stand: Best for Fifth-Wheels
The Lippert 284676 is a heavy-duty steel jack stand we found to be one of the strongest options. Designed for fifth-wheel and large travel trailers, it can handle up to 12,000 pounds of tongue weight. The welded steel construction and powder coat finish ensure long life. Owners frequently mention its rock-solid stability. However, its weight and lack of adjustability are drawbacks. It is not portable for those who need to move it frequently.
If you have a medium or lightweight trailer, this block is unnecessarily heavy and expensive. It is best for those with large fifth-wheels who prioritize maximum strength and stability over portability.
- Massive 12,000-pound capacity for heavy fifth-wheels
- Welded steel construction with anti-corrosion coating
- Large 6×6 inch top plate for jack stability
Pros: Extremely strong and durable; Stable even on soft ground
Cons: Very heavy (about 10 pounds) and bulky; No height adjustment, only a single 6-inch height
6. Camco 58115 EZ Leveler: Best for Leveling
The Camco 58115 EZ Leveler is a adaptable block that we found useful for both jack support and tire leveling. Its ribbed design allows you to drive your trailer tires onto it, making it a dual-purpose product. However, its 3,500-pound capacity is lower than many dedicated jack blocks, and the polymer material is prone to cracking if overloaded or subjected to sharp impacts. Some owners reported that the blocks broke after a few uses with heavy trailers.
If you have a small or medium trailer and want a product that can serve multiple purposes, this is a good value. But for heavy trailers or frequent use, we recommend a more strong option.
- Designed to be driven onto for leveling, not just jack support
- Ribbed surface for tire traction
- Lightweight and stackable
Pros: Can be used for both jack and tire leveling; Very easy to use
Cons: Low weight capacity limits use; Polymer can crack under heavy loads or when driven over repeatedly
7. BAL 28050 Single-Axle Trailer Jack Block: Best for Single-Axle Trailers
The BAL 28050 is a compact jack block we evaluated for single-axle trailers. Its cast aluminum construction is lightweight and rust-resistant. However, its 2,500-pound capacity and small 4×4 inch footprint make it suitable only for very light trailers. Owners noted that it can sink into soft soil and that the small top surface may not fit some jack feet securely.
If you have a heavy trailer or need a block for uneven terrain, we suggest a larger option. This block is best for small boat trailers or utility trailers used on hard, level surfaces.
- Compact and lightweight design
- Cast aluminum resists rust
- Designed specifically for single-axle trailers
Pros: Very small and easy to store; Good for light utility trailers
Cons: Very low weight capacity; Small footprint may sink in soft ground
Frequently Asked Questions
What is a trailer jack block and why do I need one?
A trailer jack block is a support placed under the tongue jack of a trailer to provide a stable, level surface. It prevents the jack foot from sinking into soft ground, reduces strain on the jack, and helps level the trailer. We recommend using one whenever the trailer is parked or stored to improve safety and longevity of the jack.
How much weight should a trailer jack block support?
The block should support at least the tongue weight of your trailer. Tongue weight is typically 10-15% of the total trailer weight. For example, a 5,000-pound trailer may have a tongue weight of 500-750 pounds. However, we recommend a block with a capacity well above your tongue weight for a safety margin. Check your trailer’s specifications.
Can I stack multiple jack blocks to increase height?
Yes, many blocks are designed to be stackable, such as the Camco 58141 set. However, ensure that the combined stack is stable and that the blocks interlock or have non-slip surfaces. Avoid stacking too high, as it may become unstable. Always follow the manufacturer’s guidelines.
What materials are best for a trailer jack block?
Common materials include polymer, rubber, aluminum, and steel. Polymer blocks are lightweight and affordable but may crack under heavy loads. Rubber is durable and non-slip but can degrade in sun. Aluminum is lightweight and rust-resistant but may bend. Steel offers the highest strength and durability but is heavy. Choose based on your trailer weight and usage conditions.
Do I need a jack block if I have a leveling system?
Yes, even with a leveling system, a jack block provides extra stability and protects the jack from damage. It also prevents the jack from sinking into soft ground. We recommend using a block under the jack as a standard safety practice.
Our Verdict
After our research and comparison, the Andersen Hitches 3604 Jack Block is our top pick for its exceptional stability, high weight capacity, and durable construction, making it ideal for heavy trailers. For a more affordable yet reliable option, the Camco 58141 Yellow Jack Leveling Block set is our runner-up, offering great value for lighter trailers and campers.
