1. Dee Zee DZ8700 Heavy Duty Wheel Well Box: Best Overall
The Dee Zee DZ8700 stands out for its rugged diamond tread aluminum construction, which we found to be among the most durable in our research. Owner feedback consistently praises its precise fit for popular truck models like Ford F-150 and Ram 1500. The push-button latch and lockable handle provide convenient yet secure access.
However, some owners report minor water ingress during extreme downpours, so if you need absolute waterproof storage, consider a sealed plastic box. Skip this if you prefer a lightweight plastic unit or have a truck with unusual wheel well dimensions.
- Heavy-duty diamond tread aluminum construction resists dents and corrosion
- Push-button latch with lockable handle secures tools and gear
- Precision fit for most full-size and mid-size trucks
Pros: Excellent build quality and finish; Easy to install with included hardware
Cons: Lid may not be completely water-resistant in heavy rain
2. UWS EC-100 Economy Wheel Well Box: Budget Pick
The UWS EC-100 offers a budget-friendly steel option that doesn’t skimp on security. In our evaluation, the recessed paddle latch and key lock provide reliable protection for basic tools and gear. Owner feedback indicates it fits most standard wheel wells with minimal adjustment.
Its smaller size limits what you can store, and the powder coat finish can chip if subjected to heavy abrasion. Skip this if you need maximum capacity or prefer aluminum for corrosion resistance.
- Affordable steel construction with durable powder coat finish
- Recessed paddle latch with key lock
- Universal fit for many truck models
Pros: Great value for the price; Solid steel build
Cons: Smaller capacity than some competitors; Paint may chip over time
3. Weather Guard 128-0-001 Wheel Well Box: Most Durable
The Weather Guard 128-0-001 is built like a tank, using 16-gauge steel and a continuous weather seal that we found to be superior in keeping out moisture. Based on owner feedback, it withstands heavy use on job sites and rough conditions. The slam latch allows one-handed operation.
Its weight (over 30 pounds) is a drawback for fuel-conscious owners, and the cost is higher than many alternatives. Skip this if you prioritize lightweight storage or have a tight budget.
- Heavy 16-gauge steel with continuous weather seal
- Recessed key lock and slam latch
- Lid opens fully for easy access
Pros: Extremely rugged and weather-resistant; Slam latch for quick closing
Cons: Heavy weight adds to truck load; Higher price point
4. Kobalt 242255 Wheel Well Storage Box: Best Value
The Kobalt 242255 offers a great balance of cost and quality. In our research, it provides reliable security with its key-lockable paddle handle and fits many truck models without modification. Owner feedback highlights its ease of installation.
Its smaller size and lack of weather sealing mean it’s best for dry climates or storing items that can tolerate some moisture. Skip this if you need to store sensitive electronics or require a larger volume.
- Affordable yet sturdy steel construction
- Key-lockable paddle handle
- Pre-drilled holes for easy installation
Pros: Excellent value for money; Compact design fits tight spaces
Cons: Limited capacity; Not weather-sealed
5. Rugged Ridge 18001.14 Wheel Well Storage Box: Best for Jeep Gladiator
The Rugged Ridge 18001.14 is a niche product tailored for the Jeep Gladiator. Our research shows it integrates smoothly with the factory wheel well contours, and owner feedback confirms a hassle-free installation. The textured finish matches the truck’s off-road aesthetic.
However, its small size and single-vehicle compatibility limit its appeal. Skip this if you don’t own a Gladiator or need a larger storage box.
- Specifically designed for Jeep Gladiator wheel wells
- Textured black finish resists scratches
- Key lock included
Pros: Perfect fit for Gladiator; Rugged appearance
Cons: Small capacity; Limited to one vehicle model
6. Buyers Products B300W Wheel Well Tool Box: Compact Choice
The Buyers Products B300W is one of the smallest wheel well boxes available, ideal for those with minimal storage needs. In our evaluation, it fits in tight spaces where larger boxes won’t, and owner feedback notes its straightforward installation.
Its tiny capacity (0.8 cu ft) means you can only store a few small items, and the white paint is prone to chipping. Skip this if you need to store anything larger than a basic tool kit.
- Compact footprint fits tight wheel wells
- Key-lockable latch
- Lightweight at 15 pounds
Pros: Very small and lightweight; Easy to install
Cons: Very limited storage space; Paint may chip
7. TruXedo Wheel Well Storage Box: Weatherproof Design
The TruXedo Wheel Well Storage Box focuses on keeping contents dry with a foam gasket seal. Our research indicates it offers better moisture protection than many steel boxes, and owner feedback confirms it holds up well in rain. The reinforced lid adds strength.
The gasket can wear out with heavy use, requiring replacement, and the capacity is adequate but not generous. Skip this if you need a truly waterproof solution like a sealed plastic box.
- Gasket seal provides enhanced weather resistance
- Key-lockable paddle latch
- Reinforced lid for added durability
Pros: Good weather protection; Sturdy construction
Cons: Gasket may degrade over time; Average capacity
Frequently Asked Questions
Will a wheel well box fit my truck?
Most wheel well boxes are designed for full-size and mid-size trucks, but fit varies by model and year. Check the manufacturer’s fitment guide and measure your wheel well (height, width, depth) before purchasing. Some boxes are universal, while others are vehicle-specific.
Are wheel well boxes weatherproof?
Most steel boxes are weather-resistant but not fully waterproof. They typically have a gasket or seal to keep out splashes and light rain. For complete waterproof protection, look for boxes with continuous weather seals or consider plastic models that are fully sealed.
How do I install a wheel well box?
Installation usually involves positioning the box in the wheel well, marking the mounting holes, and securing it with bolts or screws (often included). Some boxes use existing holes or require drilling. Always follow the manufacturer’s instructions and use the provided hardware.
Can I lock a wheel well box?
Yes, most wheel well boxes come with a key lock or a padlock hasp. Lockable latches provide security for tools and valuables. Ensure the lock mechanism is durable and weather-resistant to prevent jamming.
What is the weight capacity of a wheel well box?
Weight capacity depends on the box’s construction and mounting. Typically, steel boxes can hold 50-100 pounds, but check the manufacturer’s rating. Avoid overloading to prevent damage to the box or truck bed.
