1. UWS TBSF52BLK: Best Overall

In our evaluation of the UWS TBSF52BLK, manufacturer specifications highlight the stainless steel paddle handles and the patented MicroSeal gasket system designed to keep water out. We compared this model against others and found the foam gasket consistently rated higher in owner feedback regarding dryness during rainstorms. However, we noted reports that the self opening strut can lose tension over time in extreme cold climates, requiring manual assistance to lift the lid.
Users looking for a maintenance free experience in sub zero temperatures might want to consider a gas strut upgrade or a different mechanism. This box is ideal for contractors who prioritize weather resistance and sturdy build quality over the lowest initial investment.
- MicroSeal gasket system keeps contents dry
- Self opening gas strut for easy access
- Stainless steel paddle handles
Pros: Excellent water resistance based on owner feedback; Heavy duty aluminum construction withstands rough use
Cons: Gas strut can lose tension in extremely cold climates
2. Dee Zee DZ85: Best Runner Up

We researched the Dee Zee DZ85 and found its Brite Tread aluminum construction offers a classic aesthetic while maintaining structural rigidity defined by industry standards. Our comparison of the Roto Tech lid system suggests it provides a smoother opening motion than many stamped steel hinges, though some owners report that the latch mechanism requires occasional lubrication to prevent sticking. Based on owner feedback, the finish is durable but can show surface scratches if heavy tools are dragged across it.
This unit is a strong contender for those needing a reliable storage solution that balances capacity with ease of access. Perfectionists regarding latch smoothness should be prepared for minor upkeep to ensure the mechanism continues to operate flawlessly.
- Roto Tech lid system for smooth operation
- Heavy duty gas shocks assist the lid
- Foam gasket for weather protection
Pros: Smooth lid hinge mechanism reduces wear; Classic design fits various truck models well
Cons: Latch mechanism may require lubrication over time
3. Better Built 70320112: Best Value

The Better Built 70320112 stands out in our research for offering a high storage capacity and solid build quality at a competitive tier. We analyzed the full piano hinge design, which manufacturer specs claim provides superior strength and prevents the lid from sagging over time. However, aggregated feedback indicates that the gas charged struts included in the package can sometimes be weak upon delivery, failing to hold the lid open fully.
Buyers should check the strut functionality immediately after installation. This box is a great choice for budget conscious buyers who need a sturdy saddle box, provided they are willing to potentially replace the struts if they do not meet expectations.
- Full piano hinge for added strength
- Gas charged struts for lid support
- Self closing latch design
Pros: Strong piano hinge prevents lid sag; High storage capacity relative to footprint
Cons: Gas struts can be weak upon delivery per some reviews
4. Buyers Products 1712359: Heavy Duty Pick

Our evaluation of the Buyers Products 1712359 focuses on its heavy duty powder coat finish and durable stainless steel hardware. Manufacturer specifications emphasize the high performance coating designed to resist chipping and rust, which we confirmed is a significant advantage for users in harsh climates. Despite its durability, the increased weight of the materials makes installation physically more demanding compared to lighter gauge aluminum models.
Owner feedback suggests that while the box is tough, the weight can be a drawback for single person installation. We recommend this product for users who prioritize maximum durability and weather resistance over ease of setup.
- High performance powder coat finish
- Stainless steel locks and handles
- Compatible with most truck beds
Pros: Extremely durable powder coat resists rust; Heavy gauge aluminum provides excellent security
Cons: Heavier weight makes installation more difficult
5. Delta 48-1100: Budget Option
We compared the Delta 48-1100 and found it offers a basic entry level solution for truck owners needing essential storage. The manufacturer specifications list a full weather seal and electrostatic finish, which provide adequate protection for occasional use. However, our research indicates that the weather stripping is thinner than that found on higher end models, potentially allowing moisture ingress in driving rain.
This model is suitable for users storing moisture insensitive items or those who park in covered areas. If you require a completely dry interior for sensitive tools during heavy storms, you may need to upgrade the seal yourself.
- Full weather seal included
- Electrostatic black finish
- Easy to install design
Pros: Simple installation process; Adequate weather protection for light use
Cons: Weather stripping is thinner than premium competitors
6. Husky 62664: Basic Storage
The Husky 62664 was evaluated as a functional, no frills storage option for standard truck beds. Manufacturer details highlight the brite tread aluminum and self opening lid, which our analysis confirms offers decent utility for the price. Based on owner feedback, the primary limitation involves fitment, as the dimensions can be tight on newer or wider truck bed models, potentially interfering with bed liners or wheel wells.
We suggest measuring your truck bed space precisely before purchasing. This product is best for owners of older or standard specification trucks who need a simple box without the requirement for precise water tightness.
- Brite tread aluminum construction
- Self opening lid with shocks
- Includes two keys for security
Pros: Self opening lid is convenient; Lightweight design aids in handling
Cons: Fitment can be tight on some newer truck models
7. Lund 83710: Economy Choice
Our research into the Lund 83710 reveals it is an economy level option that provides basic security and storage. The manufacturer specifications describe a diamond tread plate design and gas shocks, which are standard features at this level. However, we found that the metal gauge is thinner compared to our top picks, making the box more susceptible to denting if heavy objects are dropped against it or during rough use.
This unit is appropriate for light duty storage where the box will not face heavy impact. Users who transport heavy tools or equipment regularly should consider a more strong option to avoid deformation of the body.
- Diamond tread plate design
- Gas shocks for lid lift
- Positive latch system
Pros: Diamond tread offers a rugged look; Gas shocks assist with opening
Cons: Metal gauge is thinner leading to easier denting
Frequently Asked Questions
How do I measure my truck for a fender well box?
We researched installation guidelines and found you must measure the width of your truck bed between the wheel wells and the depth from the bedside to the wheel well. Manufacturer specifications usually list the minimum bed width required. Always compare these dimensions with your truck bed measurements to ensure the box fits without obstructing tailgate operation.
Are aluminum fender well boxes as strong as steel?
In our comparison of materials, aluminum boxes offer a high strength to weight ratio and resist rust naturally, while steel boxes are heavier and often require powder coating to prevent corrosion. Aluminum is generally sufficient for most tool storage needs, but steel provides superior impact resistance if you anticipate heavy abuse.
Will a fender well tool box leak in the rain?
Based on our evaluation of weather seals, most high quality boxes use foam gaskets to prevent water entry. However, we found through owner feedback that no box is completely submersible. Models with the MicroSeal system or thick rubber gaskets performed best in our research, while economy models may allow some moisture during heavy storms.
Do these boxes come with mounting hardware?
Our analysis indicates that most fender well tool boxes include the necessary hardware such as bolts and nuts, but they do not always include specific mounting brackets for every truck bed configuration. You may need to drill into the truck bed or wheel well for installation, so checking the included hardware list is essential.
Can I sit on a fender well tool box?
We compared manufacturer load ratings and found that while some heavy duty models can support significant weight, sitting on the lid is generally not recommended. The gas struts and latches are designed for the lid weight only, and placing a person’s full weight on the box can damage the hinges or compromise the weather seal.
Our Verdict
Based on our research and comparison, the UWS TBSF52BLK is the top pick for its superior weather resistance and solid build quality. The Dee Zee DZ85 is the runner up, offering a reliable design with smooth lid operation.
