1. Rugged Ridge Black Steel Cargo Box: Best Overall
In our evaluation, the Rugged Ridge Black Steel Cargo Box stands out for its robust build and straightforward mounting. The steel construction and powder coat finish provide excellent resistance to impacts and corrosion, making it a long-lasting choice for truck owners who prioritize security. The lockable latch adds peace of mind, and the 4.5-cubic-foot capacity is sufficient for tools, emergency gear, or camping supplies. Based on owner feedback, installation takes about 20 minutes using the included hardware and existing bed tie-downs.
However, the steel box is noticeably heavier than aluminum or plastic alternatives, which may reduce payload capacity slightly. If you need a lightweight option for frequent removal, consider a plastic model. Also, the box lacks internal dividers, so smaller items may shift during travel. This box is best for those who want a permanent, heavy-duty storage solution and don’t mind the extra weight.
- Heavy-duty steel with black powder coat finish resists rust and dents
- Lockable latch with key for secure storage
- Easy bolt-on installation using existing bed tie-down points
Pros: Extremely durable steel construction; Simple no-drill installation
Cons: Heavier than aluminum or plastic boxes
2. Dee Zee Heavy Duty Aluminum Cargo Box: Best Aluminum
We researched the Dee Zee Heavy Duty Aluminum Cargo Box and found it offers a great balance of weight and durability. The diamond plate aluminum is both attractive and functional, providing a non-slip surface. The 5-cubic-foot capacity is generous, and the gas spring lid assist makes access effortless. The rubber seal helps keep contents dry, though we note that prolonged heavy rain may still allow some moisture ingress based on owner reports.
The main limitation is that aluminum is softer than steel, so it can dent if struck by heavy cargo. Also, the mounting brackets are not universal and may require minor adjustments on some truck beds. This box is an excellent choice for those who want a lighter box that won’t significantly impact fuel economy or payload, but if you need maximum impact resistance, a steel box is better.
- Lightweight aluminum with diamond plate tread for grip and style
- 5 cubic feet of storage with gas spring lid assist
- Includes rubber seal to keep out dust and moisture
Pros: Lightweight yet sturdy; Gas springs make lid easy to open
Cons: Aluminum can dent more easily than steel
3. UWS Low Profile Truck Tool Box: Best Low Profile
Our evaluation of the UWS Low Profile Truck Tool Box shows it is ideal for truck owners who need to maintain rear visibility. The low profile sits just above the bed rails, so it doesn’t block the rear window. The push-button lock is convenient, and the weather seal does a good job keeping out dust. Based on spec sheets, the aluminum construction is corrosion-resistant and lightweight.
However, the shallow depth means you cannot store tall items like upright shovels or long-handled tools. Also, some owners report that the weather seal can degrade over time in extreme sun, requiring replacement. This box is best for those who prioritize visibility and have smaller items to store, but skip it if you need to haul bulky gear.
- Low profile design does not obstruct rear window visibility
- Push-button lock with key override for security
- Built-in weather seal to protect contents
Pros: Excellent visibility over the box; Sleek, modern look
Cons: Limited depth may not fit larger tools
4. Weather Guard Heavy Duty Cargo Box: Most Durable
The Weather Guard Heavy Duty Cargo Box is built to last, with heavy-gauge steel and stainless steel hardware. In our research, it consistently ranks high for durability among owner reviews. The 6-cubic-foot capacity is one of the largest available, suitable for storing multiple tool boxes or camping gear. The lockable latch provides security, and the paint finish resists chipping.
On the downside, the box is extremely heavy, which can significantly affect fuel economy and available payload. Installation is also more involved, often requiring drilling for proper mounting. Additionally, the price point is higher than many competitors, making it a less attractive value for casual users. This box is best for commercial or heavy-duty use where durability is paramount, but not for everyday light-duty truck owners.
- Heavy-gauge steel with automotive-grade paint finish
- Stainless steel hinges and lock rod for longevity
- Large 6 cubic foot capacity for bulky items
Pros: Extremely rugged construction; Large capacity
Cons: Very heavy, reduces payload noticeably
5. Buyers Products Aluminum Cargo Box: Best Value
We compared the Buyers Products Aluminum Cargo Box and found it offers solid value for those on a budget. The aluminum diamond plate is lightweight and rust-resistant, and the 3-cubic-foot capacity is adequate for storing a few tools or emergency supplies. The included mounting hardware and weather stripping simplify installation. Based on owner feedback, the box holds up well in typical use.
However, the smaller size may not suit those with more gear, and the latch mechanism feels less robust than pricier models. Some owners report that the weather stripping can come loose over time. This box is a good entry-level choice for occasional use, but serious truck owners may want to invest in a larger, more durable option.
- Affordable aluminum construction with diamond plate
- 3 cubic foot capacity for essentials
- Includes mounting hardware and weather stripping
Pros: Budget-friendly price; Corrosion-resistant aluminum
Cons: Smaller capacity than many competitors
6. Truck Bed Cargo Box by Rage Powersports: Best for ATVs
The Rage Powersports Truck Bed Cargo Box is made from UV-resistant polyethylene, making it immune to rust and dents. It is lightweight and easy to install or remove, with tie-down loops that help secure items. The 4.2-cubic-foot capacity is decent for recreational gear. In our evaluation, it appeals to ATV and off-road enthusiasts who need a box that can withstand the elements without adding much weight.
However, the plastic construction feels less premium than metal boxes, and some owners report that the lid seal is not completely watertight during heavy downpours. The locking mechanism is also basic and may not deter determined thieves. This box is best for those who prioritize weight savings and rust resistance over security and absolute weather protection. Skip it if you need a secure, weatherproof storage solution.
- UV-resistant polyethylene won't rust or dent
- 4.2 cubic foot capacity with tie-down loops
- Lightweight design for easy handling
Pros: Rust-proof and lightweight; Tie-down loops for securing cargo
Cons: Lid seal may leak in heavy rain
7. Voodoo Tactical Cargo Box: Best Tactical
The Voodoo Tactical Cargo Box is a unique soft-sided option designed for tactical and outdoor enthusiasts. It features MOLLE webbing on the exterior for attaching pouches, and internal organizer pockets for small items. The lockable zippers provide basic security, and the reinforced handles make it easy to carry. Based on spec sheets, it is made from heavy-duty nylon over a plastic frame, offering moderate protection.
However, this box is not waterproof; it is only water-resistant, so contents can get wet in heavy rain. The soft sides also offer less protection against impacts or theft compared to hard-sided boxes. Additionally, the 3.5-cubic-foot capacity is smaller than many hard boxes. This cargo box is best for those who need a soft, portable organizer for gear, but it is not suitable for securing valuable tools or items that must stay dry.
- Heavy-duty nylon exterior with MOLLE webbing for accessories
- Internal organizer pockets and divider panels
- Lockable zippers and reinforced carry handles
Pros: Highly customizable with MOLLE system; Organized interior pockets
Cons: Not waterproof, only water-resistant
Frequently Asked Questions
What size cargo box do I need for my truck?
The right size depends on your bed dimensions and storage needs. Measure the available space between your wheel wells and tailgate. For most full-size trucks, a box between 4 and 6 cubic feet is common. Compact trucks may need smaller boxes. Consider what you plan to store: toolboxes, camping gear, or emergency kits.
Are cargo boxes waterproof?
Most hard-sided cargo boxes are weather-resistant but not fully waterproof. They typically have rubber seals that keep out rain and dust, but prolonged submersion or heavy pressure washing can cause leaks. Soft-sided boxes are generally only water-resistant. If you need absolute waterproofing, look for boxes with gasket seals and test them.
How do I install a truck cargo box?
Installation varies by model. Many boxes use clamp-on or bolt-on mounting systems that attach to existing bed tie-down points or rails. Some require drilling holes for a more permanent fit. Always follow the manufacturer’s instructions and use the included hardware. For heavy boxes, consider a second person for lifting.
Can I lock a cargo box to prevent theft?
Yes, most cargo boxes come with built-in lockable latches or hasps. Some use keys, while others have combination locks. For added security, you can use padlocks or cable locks. However, no lock is completely theft-proof; choose a box with a robust locking mechanism and consider parking in secure areas.
Will a cargo box affect my truck's fuel economy?
A cargo box can affect aerodynamics and add weight, potentially reducing fuel economy. The impact is usually small, especially with low-profile or aluminum boxes. Larger, heavier steel boxes may have a more noticeable effect. If fuel economy is a concern, choose a lightweight, aerodynamic model.
Our Verdict
Our top pick is the Rugged Ridge Black Steel Cargo Box for its excellent balance of durability, security, and ease of installation. It is a reliable choice for most truck owners. For those seeking a lighter option, the Dee Zee Heavy Duty Aluminum Cargo Box is a strong runner-up, offering generous capacity and corrosion resistance.
