Best Truck Tool Boxes Reviews & Recommendations

Best Overall
Buyers Products Diamond Tread Aluminum Underbody Truck Box

When it comes to the best overall choice for a rugged, durable, and well-priced truck tool box, our pick is the Buyers Products 1705115 Diamond Tread Aluminum Underbody Truck Box. This is a traditionally styled 60-inch truck toolbox that’s constructed from .100-inch thick diamond tread aluminum that’s built to withstand extreme weather conditions. It’s corrosion- and dent-resistant, and will hold up well against some serious wear and tear. This tool box comes equipped with a locking, die-cast compression latch system that not only protects your tools and gear from weather, but from theft as well. 

Constructed with aircraft-grade cables and a tough, replaceable gasket sealing system, this tool box and its contents aren’t going anywhere. It’s made to mount on a flat truck bed, or you can also mount it under the bed on larger trucks. The reinforced, recessed drop-door is built to be rattle-free. There have been a few customer complaints about quality control issues with this particular model, but rest assured that customer service responses have been timely and sufficient to satisfy most buyers. 


  • Brand: Buyers Products
  • Model: 1705115
  • Weight: 66 pounds


  • Sleek styling
  • Equipped with a solid die-cast, locking compression latch
  • Reinforced recessed drop door


  • A little pricey
  • Some units arrive with unfinished welds
  • Doesn’t include mounting brackets with your purchase
Best Value
UnderCover SwingCase

Throwing out the book on traditional truck tool box design, UnderCover created the SwingCase to appease truck owners who want to keep their beds covered and usable at the same time. As a result, this box fits below the bedrail, staying clear of a tonneau cover and opening up the main usable bed space between the wheels. In addition to a good value, this tool box also offers a lot of utility for professionals and daily drivers alike.

Each case comes in a paired set, so you can install one tool box on each side of the truck. A curved cutout on the bottom of the box allows it to fit over the wheel, flush with the bed's side. The best part of the box's design is the hinge that allows it to swing out over the tailgate. The hinge makes it easy to access the box without having to dive into the tailgate with the cover closed. The SwingCase is designed with portability in mind, which is both a benefit and drawback. Since you can slide the tool box out of the hinge to take it with you, the main body is light and small. With a 75-pound weight limit, the storage capacity of the SwingCase is more limited than traditional tool boxes.


  • Brand: Undercover
  • Model: ‎SC100D
  • Weight: 20 pounds


  • Works with your tonneau cover
  • Makes good use of awkward over-the-wheel space in your truck bed
  • Comes as a set of two for each side of your truck


  • Smaller than most traditional truck tool boxes
  • Lacks the space to accommodate larger or more awkward tools
  • Not compatible with all truck makes and models
Most Versatile
TruXedo TL TonneauMate

We like the TruXedo TL TonneauMate for its lightweight, rugged construction. It’s made from a heavy-duty composite that’s fully water- and rust-proof, giving you years of reliable use. It’s able to accommodate a tonneau cover while being mounted in an elevated position that allows you use of the full length of your truck bed. It also features a versatile adjustable mounting design and can be placed in the front, middle, or rear of your truck bed. 

This model is affordable and is also compatible with most full-size truck beds, with the exception of stepside, flareside, or composite beds. It features a locking mechanism for added safety and theft-protection, although several users complain that the lock itself is tricky and can be frustrating to get into in a hurry. The composite construction looks good and hides scratches that some other all-metal boxes reveal, but if you live in a climate with lots of harsh weather, this box may not hold up as well over time as a pricier, all-metal model. For the price point though, it’s still an excellent value.


  • Brand: Truxedo
  • Model: 1117416
  • Weight: 54 pounds


  • Affordable
  • Can be mounted in several different spots on your truck
  • Compatible with tonneau covers


  • Not compatible with all tonneau covers or truck makes and models
  • Mounting bracket system needs to be a little stronger
  • May not hold up as well over time as an all-metal tool box
Best Looking
UWS Truck Tool Box With Low-Profile Lid

This offering from UWS is a little pricier than some other models on our list, but for your dollar, you get an extra-thick aluminum walled matte black truck box that’s constructed from welded 0.058-inch aluminum. You also get UWS’ signature RigidCore lid, which is built with patented technology to be maximally strong and minimally binding and opens a full 90 degrees. Its low profile allows you to have a better view out of your truck’s rear window. You’ll like the sleek, understated look of this tool box, as well as the fact that it comes with a tool tray and built-in screwdriver holders for those who really want to stay organized.

This particular model is designed for full-size pickup trucks, measuring 17 x 77 x 24 inches. It also gets high marks for being easy to install. The one annoyance that several users note is that the tool tray tends to slide and bang around while driving, and should have an anchor system to keep it in place. There are also reports that the supplied J-hooks that are used to secure the box to the rail can actually start to bend the rails as you tighten them down, so you may want to consider other mounting methods.


  • Brand: UWS
  • Model: EC10473
  • Weight: 58 pounds


  • Easy to install
  • Low profile allows for full view out of your rearview window
  • Lid opens a full 90 degrees to allow easy access to the entire tool box


  • Only fits in full-size truck beds
  • Included tool tray tends to slide around during driving
  • Included J-hooks for mounting may damage the rails on the side of your truck
Best For Smaller Truck Beds
Arksen Aluminum Diamond Plate Tool Box

The Arksen underbed storage box is available in both 24 and 36 inches. It's designed for heavy-duty trucks and features a T-handle latch and dual locks for security and to prevent theft. It has a rugged, rotary-style, two-position latch and a weather seal to lock moisture out. It's made of corrosion-resistant aluminum diamond plate and has a polished black finish that looks modern and rugged. This tool box is lightweight but durable. 

It's fully waterproof, and the plastic cap over the keyhole is a nice feature to lock out moisture. You know this tool box will withstand some serious abuse. You can secure it or weld it directly to the truck bed, and it has plenty of room for tools, gas cans, straps, hitches, and so on. Overall, it's a great value for what you get. Unfortunately, this box is not particularly heavy-duty, and the aluminum is a little on the thin side. Also, each lock requires a separate key, which is a little inconvenient. Another drawback is that the black polished finish can tend to get really hot to the touch in direct sunlight.


  • Brand: ARKSEN
  • Model: 002-36UB-DP-BK
  • Weight: 22 pounds


  • Can fit in smaller truck beds
  • Features two solidly built, durable locking latches
  • Affordable


  • Limited storage capacity compared to larger tool boxes
  • Black polished finish gets hot to the touch in prolonged sunlight exposure
  • Not as ruggedly constructed as some other models on our list

How We Selected The Products 

Our goal with this guide was to select a well-rounded and versatile group of top-quality truck tool boxes that are suitable for a variety of different situations. Not all trucks are created the same and not all truck owners have the same needs, so keeping that in mind, we sifted through dozens of potential options to produce a well-rounded group of selections. We only considered truck tool boxes made by reputable and long-standing manufacturers. We sifted through hundreds of online user evaluations and real customer feedback to come up with the truck tool boxes that get lots of love from satisfied purchasers.  

Our product selections, rankings, and awards for this story are based on research. While we haven’t conducted real-world testing yet on all of these products, we’ve looked at consumer testimonials and data, tutorials, and general discussions on social media and in forums. We also consider price and specification in the context of the segment. And, of course, we rely on our institutional knowledge of the automotive landscape to weed out weak products.

Buying Guide/What to Look For 

Why Buy a Truck Tool Box

  • Organize and haul small items. Since a truck bed is just one large rectangle, storing small items can be difficult when you don't want loose items floating around as you drive. A tool or storage box provides a simple and convenient storage space to contain small objects so everything stays in place.
  • Protect valuables. While most truck tool boxes aren't bank vaults, the basic locks and latches they provide are good for general tool storage and protection. The average tool box is secure enough to deter all but the most motivated would-be thieves.
  • Free up the pickup truck bed. Fewer small items in the truck bed mean more usable space for larger things. Some tool boxes sit above the floor of the bed, so it's easier to haul longer or more awkward items while still taking advantage of the space above.

Types of Tool Boxes for Trucks

Saddle Tool Box

Also known as a crossover toolbox, this is arguably the most traditional form of a truck tool box. Spanning from one side of the bed to the other, this design straddles the bed so it floats above the floor. Many saddle boxes offer more flexible mounting options and preserve the space underneath for longer items.

Chest Tool Box

If you were to take a typical garage tool box and place it in a pickup bed, you'd have the basic ingredients of a low-profile, chest-style truck box. Chest boxes usually sit on the floor of the bed and can provide more space for tools at the expense of space in the bed. They are accessible via a single lid and tend to be simpler in design and installation.

Side Mount Tool Box

Side-mounted truck boxes often run the length of the truck bed while preserving the center. This type of tool box plays well with camper shells and tonneau covers, especially if the box sits below the bed rail line. Most side-mounted setups use two boxes for each side of the bed.

Underbody Tool Box

As the name implies, these super heavy-duty, large-capacity tool boxes mount on the underside of your vehicle’s frame. They’re usually reserved for use in larger commercial vehicles, such as tow trucks and tractor trailers. They provide easy access from the side of the truck and come in a wide variety of sizes.

Wheel Well Tool Box

Wheel Well tool boxes are a fairly ingenious design that maximize storage space and efficiency in the back of your truck. They’re cut with a round shape that fits over the wheel well and may or may not be mounted on swinging hinges near the tailgate so that you can swing them toward the back of the truck to access your gear. They’re slimmer and smaller in capacity than other types of tool boxes, but they’re an excellent option for storing smaller tools and other gear.

Top Brands of Truck Tool Boxes

Buyers Products

Buyers Products was founded in 1946 and is an Ohio-based company. A leader in the truck equipment industry, Buyers Products is proud that all of its engineering, manufacturing, and assembly takes place in the United States. Check out the Buyers Products Black Diamond Tread Aluminum Gull Wing Truck Box and the Buyers Products Heavy Duty Diamond Tread Aluminum Step Box for some innovative storage solutions. 


TruXedo was founded in 2000 as a division of Shur-Co., a South Dakota-based company. It has grown into the largest manufacturer of soft roll-up tonneau covers, like the TruXedo TruXport. The company was purchased by a private equity firm in 2007 as part of a larger umbrella of truck products and accessories.


Originally a one-piece truck cover manufacturer, UnderCover has quickly expanded its line of tonneau covers and accessories since its founding in 1999. In addition to different types of tonneau covers, the company introduced its line of SwingCase Toolboxes to offer more value and utility to its customers.

Key Features

Weatherproof Protection

The main purpose of a tool box, besides organization, is protection. Beyond theft prevention, the best protection a tool box can provide is weather protection. Weather-resistant protection comes in the form of quality exterior materials and a proper weather seal around the seams of the box. The best options can keep out the rain and survive a few knocks from hail or rust from water. Look at stainless steel boxes and heavy-duty aluminum tool boxes with a good powder coat for the best corrosion-resistant protection.


Theft prevention is an important component to truck beds in general since they lack the inherent security of enclosed cargo spaces like trunks. A tool box with a high-quality, smooth-running lock makes it more difficult to open the lid, which deters casual thieves from stealing the contents.

Lid and Gas Lift

If you plan on using your tool box a lot, a high-quality lid is a must. In addition to weather and theft resistance, the lid should open and close smoothly. Good gas lifts to support the lid help with smooth operation since they can take the weight of the lid and control the movement while you're opening and closing it.


  • Buy a tool box with some internal dividers or compartments to add more tool organization to your setup.
  • Tool chests are a good type of toolbox to consider if you want something that can work with tonneau covers. Not all chest designs are short enough to work, but many sit right below the bed rail line.
  • Almost all tool boxes will work with camper shells unless they interfere with the shell's placement on the bed rails. Measure the box's overhang to see if it may present a problem.
  • Some tool boxes will require drilling into the side of the truck bed for installation. This is where professional installation may be preferable if you aren't comfortable modifying the truck yourself.
  • Add some style to your truck with a color-matched powder coating. You can also choose a black powder coat or a plane diamond-plate steel surface if you want something that goes well with different colors and styles.


Q. What style of tool box is the best?

While there is no one style of truck tool box that can definitively be called the best, we prefer the versatility of a tool box that can be mounted either in the truck bed or under the truck for easy access, depending on the type of truck you own. 

Q. What do I need to measure to see if a tool box will fit?

When measuring the space for your truck tool box, the most important number to get right is the length of the box. The outside length of the tool box must measure slightly less than the inside width of your truck bed, or the undermounting space that you plan to use. If you use larger tools, be sure to measure the inside length and width of the tool box to ensure that it will be able to accommodate larger tools.

Q. What can I store in a tool box?

The possibilities are endless. Smaller items, like hardware, wrenches, saws, etc. are perfect for storing in your truck tool box. However, you can also store hunting gear, emergency supplies, sporting goods, beach gear, and anything else you don’t want to get wet or damaged from rolling around in the back of your truck.

Final Thoughts

Now that you know what to look for in a top-quality truck tool box, it’s easy to see why the Buyers Products 1705115 Diamond Tread Aluminum Underbody Truck Box is our top pick. It’s constructed from .100-inch thick diamond tread aluminum that’s built to withstand extreme weather conditions. It’s corrosion- and dent-resistant, and will hold up well against some serious wear and tear. This toolbox comes equipped with a locking, die cast compression latch system that not only protects your tools and gear from weather, but from theft as well. 

Our budget-friendly pick, the UnderCover SwingCase, is also an excellent choice that won’t break the bank and will keep your gear safe and organized.
