Start 6 Months FreeChoosing the best tool box for a Chevy Silverado 1500 is less about the box than about the truck around it. Silverado beds changed with the 2019 redesign, the MultiPro tailgate and the CarbonPro composite bed create fitment exclusions, and the single most common regret we found in owner discussions is buying a crossover box that then fights with a tonneau cover.
That is why this guide sorts the options by how they mount: over-the-rail crossover boxes, wheel-well swing boxes, a full-depth bed-mounted box and an underbody box. We built a pool of candidate listings, checked manufacturer and dealer fitment data, read owner forums and applied rating screens to what remained. Six products made the list; several well-known names did not, and we say why below.
Rating figures below are snapshots from listing and retailer pages, so check the star count on each listing before you buy. Everything below is research-based; we did not physically test these boxes.

1. UWS EC10473 Low-Profile Crossover
The UWS EC10473 is the lowest-risk pick for most Silverado 1500 owners: a 69-inch aluminum crossover with a foam-filled lid, a gasketed seal and a tray, listed for Fleetside Silverado 1500 trucks from 1999 through 2026.

Two lids open like gull wings, so you can reach half of the box from either side of the truck. The UWS EC10061 is the pick if you work out of your bed from both sides.

Weather Guard’s 121-52-03 offers 10.2 cubic feet in a low-profile saddle box, with the 1KEY ULTRALOCK and a full weather seal. It is the largest box here by listed volume, but reviewer notes on weld quality are mixed.

If you want storage that does not touch the bed at all, the Buyers 1702305 is a 14-gauge steel underbody box made in the USA, with a T-handle latch. It is a universal frame-mount, so fitment on a Silverado needs checking.

Best Overall Tool Box for Chevy Silverado 1500
1. UWS EC10473 69-Inch Matte Black Low-Profile Crossover Tool Box
Specifications
Type: Low-profile crossover (saddle) box
Material: 0.058-inch aluminum, matte black, RigidCore foam-filled lid
Fitment: 1999–2026 Chevy Silverado 1500 Fleetside, per AmericanTrucks fitment data
Capacity: 8.4 cubic feet; removable tool tray; roughly 68–77 lb depending on source
Warranty: Limited lifetime warranty (finish and parts are covered for 1 year)
Rating: About 4.4/5 from 150+ Amazon ratings
Today’s Best Deals
View at AmazonReasons to buy
- Fitment data covers Fleetside Silverado 1500 trucks from 1999 to 2026
- Low profile keeps the rear window sightline clearer than a full-height box
- Foam-filled lid and MicroSeal gasket for weather and sound control
- Stainless handles and an included tool tray
Reasons to avoid
- An over-the-rail crossover box usually conflicts with a tonneau cover
- Matte finish shows scuffs from daily use
- Rating count is far smaller than the SwingCase or Buyers picks
The UWS EC10473 earns Best Overall because it is the most straightforward answer to the question most Silverado 1500 owners are really asking: where does a full-width box go without making the truck harder to live with? It is a 69-inch crossover, also called a saddle box, that sits behind the cab and spans the bed. Owners on Silverado forums repeatedly praise UWS boxes for being low enough to step over, with one commenter describing how easily they can “jump on it without bending.” Amazon snapshots we reviewed showed roughly 4.4 stars from 150-plus ratings, which is a modest volume but consistent with that forum sentiment.
Audible Premium Plus — Annual Membership
12 audiobook credits up front, plus the full Audible catalogue.
See Annual PlansOn paper, the build is solid for the category. UWS lists 0.058-inch aluminum, a foam-filled RigidCore lid, a MicroSeal gasket for the lid seam, stainless steel handles and an included tool tray, with 8.4 cubic feet of storage. Sources put the shipping weight at about 68–77 lb, which matters if you watch payload (our Silverado 1500 payload chart is a good place to start). The warranty is a limited lifetime term, though UWS states a one-year term for the finish and parts, so read the fine print.
The honest weakness is the one every crossover box shares: it sits above the bed rails, so it competes with a tonneau cover for the same space. If you run a hard folding or roll-up cover, you will either lose the cover’s full-length coverage or need a different box style. A low-profile box also gives up some depth compared with a tall one; 8.4 cubic feet is generous but not the largest here.
If a tonneau is in your plans, the SwingCase wheel-well box is the better fit. If you want the most storage and do not mind the extra mass, the Weather Guard saddle offers more volume.
Before you buy: confirm your Silverado 1500 is a Fleetside bed (not Stepside), and check the listing’s fitment chart for your model year and bed length. Verify the box clears your bed rails, any bed lighting and a tonneau cover if you run one.
Best Wheel-Well Tool Box for Chevy Silverado 1500
2. UnderCover SwingCase SC104D Driver Side Swing Out Storage Box
Specifications
Type: Wheel-well swing-out box (driver side, SC104D; passenger side is SC104P, ASIN B07K9Q2D16)
Material: ABS plastic with key lock and moisture seal
Fitment: 2019–2026 Silverado 1500 (new body); not Silverado 1500 Limited, MultiPro tailgate or CarbonPro bed
Capacity: 75 lb capacity; sliding tray
Warranty: 1 year
Rating: About 4.2/5 from 1,300+ Amazon ratings (listings show 4.1–4.6)
Today’s Best Deals
View at AmazonReasons to buy
- Works with virtually all tonneau covers, with about 3 inches of clearance
- Swings roughly 180 degrees so you do not climb into the bed
- Keeps the bed floor open for cargo
- Largest rating volume of any Silverado-specific pick
Reasons to avoid
- Fitment is restricted: not for the Limited, MultiPro tailgate or CarbonPro bed
- Some soft tonneaus with low clamps, or hard tonneaus with shock lifts, may interfere
- Lower capacity than a crossover box; the driver and passenger sides are separate listings
- Rating snapshots disagree and sit near the 4.2-star cutoff
The UnderCover SwingCase SC104D is the pick for Silverado owners who already have a tonneau cover or plan to buy one. It mounts against the wheel well, swings out to give you access from outside the bed, and leaves the full bed floor free. UnderCover says it fits virtually all tonneau covers with about 3 inches of clearance, and owner discussions agree that wheel-well boxes are the usual workaround when an over-the-rail crossover will not coexist with a cover.
Amazon rating snapshots we saw were not consistent: 4.1 stars on one regional page, about 4.2 from roughly 1,300 ratings on the US page, and 4.6 on a retailer. We treat it as roughly a 4.2-star product with a large rating volume, which is why it sits second instead of first. The spec sheet is straightforward: ABS construction, a 75 lb capacity, a key lock, a moisture seal and a sliding tray. Installation uses six self-tapping screws, and the warranty is one year.
Fitment is the catch. This listing is for the 2019–2026 new-body Silverado 1500 only. It does not fit the Silverado 1500 Limited, trucks with the MultiPro tailgate, or the CarbonPro bed, and some soft tonneaus with low clamps or hard tonneaus with shock lifts may interfere. Some higher trims also have bed lighting or a bed inverter that can create clearance problems for wheel-well boxes. You also need to choose the driver or passenger listing, and a single box is a smaller volume than a crossover.
If you do not run a tonneau cover and want more storage, step up to the UWS EC10473 or the DECKED Tool Box.
Before you buy: confirm your Silverado 1500 is a 2019–2026 new-body truck, that it does not have the MultiPro tailgate or CarbonPro bed, and which side you want (SC104D is driver, SC104P is passenger). Check clearance with your tonneau cover’s clamps.
Best Premium Tool Box for Chevy Silverado 1500
3. DECKED Truck Tool Box, Full Depth, Without Ladder
Specifications
Type: Full-depth bed-mounted tool box
Material: Not specified in our sources; see DECKED’s product page
Fitment: Nearly all full-size trucks 2001+; not CarbonPro bed or Silverado EV
Capacity: 73.4 gallons; torsion-spring lid
Warranty: See DECKED’s product page
Rating: About 4.8/5 from roughly 770–900 reviews on DECKED’s site
Today’s Best Deals
View at AmazonReasons to buy
- Roomy at 73.4 gallons, roughly 9.8 cubic feet
- Torsion-spring lid
- Strong review scores on DECKED’s own site
- Listed for nearly all full-size trucks from 2001 on
Reasons to avoid
- Not for CarbonPro beds or the Silverado EV
- Review evidence comes mainly from DECKED’s own site
- A full-depth box takes up a large share of bed space
- Premium-tier product; confirm the exact configuration on the listing
The DECKED Tool Box is the premium choice, and the label reflects positioning rather than a test result. It is a full-depth, 73.4-gallon box that DECKED lists for nearly all full-size pickups from 2001 on, and the manufacturer’s own site shows about 4.8 stars from roughly 770 to 900 reviews. That is strong, but those are DECKED’s own figures rather than Amazon’s.
The standout spec is capacity: 73.4 gallons (roughly 9.8 cubic feet) is far more than any wheel-well box here and close to the largest crossovers. The lid uses a torsion spring. Pairing it with a tonneau cover is a fitment question that depends on bed length and cover type, so confirm it with DECKED before you buy a cover to match.
The trade-offs are space and exclusions. DECKED states it does not fit CarbonPro beds or the Silverado EV, so owners of those trucks should skip it. A full-depth box consumes a meaningful slice of the bed, which is the point for people who want everything in one lockable place and a problem for those who haul tall loads. Some forum owners also mention that a narrow crossover box can sit in the gap behind the cab on an 8-foot bed, a configuration to research if you want to combine storage types.
If you want a more conventional, lower-profile box, the UWS EC10473 is the simpler option. For under-tonneau storage, see the SwingCase.
Before you buy: confirm your Silverado 1500 is not a CarbonPro-bed truck, check bed length and the box dimensions against the listing, and verify how it interacts with a tonneau cover, bed liner or toolbox accessories.
Best Gull-Wing Tool Box for Chevy Silverado 1500
4. UWS EC10061 69-Inch Bright Aluminum Gull Wing Crossover Tool Box
Specifications
Type: Gull-wing (two-lid) crossover box
Material: 0.058-inch aluminum, bright finish; RigidCore lids
Fitment: 69-inch crossover for full-size trucks; confirm Silverado 1500 fitment on the listing
Capacity: 8.5 cubic feet; self-opening struts
Warranty: UWS limited lifetime warranty; confirm terms on the listing
Rating: 4.5–4.8/5 from only 3–6 retailer reviews
Today’s Best Deals
View at AmazonReasons to buy
- Half-box access from either side of the truck
- Foam-filled lids and self-opening struts
- Same 0.058-inch aluminum build as our top pick
- 8.5 cubic feet of storage
Reasons to avoid
- Very few retailer reviews (3–6)
- Bright aluminum shows fingerprints and scratches more than matte black
- Over-the-rail crossover that competes with a tonneau cover
- Taller lid assemblies than the low-profile Best Overall pick
The UWS EC10061 is the gull-wing alternative to our Best Overall pick. Instead of one lid that lifts from the side, it has two lids that open upward from the center, so you can stand on either side of the truck and reach half of the box. For anyone who uses the bed as a work station, that is a real convenience compared with a single-lid box that favors one side.
The specs are close to the EC10473: 0.058-inch aluminum, RigidCore foam-filled lids and self-opening struts, with 8.5 cubic feet of storage. UWS rates this box for full-size trucks, but the listing’s exact fitment for the Silverado 1500 should be confirmed by the buyer before ordering. The finish is bright aluminum rather than matte black, which looks good when clean and shows scratches over time.
The caution here is the evidence base. Retailer listings show 4.5–4.8 stars, but from only 3 to 6 reviews, which is too thin to rank it higher, and it would not pass a strict rating-count gate on its own, so we include it as a style-driven pick and flag that clearly. As with any over-the-rail box, it also conflicts with most tonneau covers.
If you want the same brand and the same footprint with lower risk, the EC10473 is the safer choice.
Before you buy: confirm your Silverado 1500’s model year, bed length and bed width against the listing’s fitment chart, and confirm the lids clear your rear window and any tonneau cover.
Best High-Capacity Tool Box for Chevy Silverado 1500
5. Weather Guard 121-52-03 Low-Profile Saddle Tool Box
Specifications
Type: Low-profile saddle crossover box
Material: Aluminum
Fitment: Full-size truck beds; confirm Silverado 1500 fitment on the listing
Capacity: 10.2 cubic feet; 72 x 20.5 x 18.5 inches; about 133 lb
Locking: 1KEY ULTRALOCK; PowerSync-capable
Warranty: Limited lifetime warranty
Rating: Retailer ratings range from 4.0 to 4.8/5
Today’s Best Deals
View at AmazonReasons to buy
- Largest listed volume of the picks at 10.2 cubic feet
- 1KEY ULTRALOCK and a full weather seal
- PowerSync-capable
- Limited lifetime warranty
Reasons to avoid
- About 133 lb, the heaviest box in this guide
- Some reviewers report weld, dent and quality-control problems
- Retailer ratings are mixed: 4.3 (10 reviews), 4.0 (37) and 4.8 (153) on different retailers
- Over-the-rail box that competes with a tonneau cover
The Weather Guard 121-52-03 is for the owner who needs the most room. At 10.2 cubic feet and 72 x 20.5 x 18.5 inches it is the largest box on our list by volume, and Weather Guard pairs it with the 1KEY ULTRALOCK and a full weather seal. It is also PowerSync-capable, which is relevant if you plan to add a compatible power system.
Weather Guard is an established name among truck owners, and Silverado forum members cite it alongside UWS and CamLocker as a brand they would buy. Warranty coverage is a limited lifetime term. The spec sheet is strong for people who haul gear, but the weight is notable at about 133 lb, which affects payload and installation effort.
Reviews are where it gets uneven. One retailer shows 4.3 stars from 10 reviews with complaints about welds, dents and quality control, another shows 4.0 from 37 reviews on a sibling part number, and a third shows 4.8 from 153. We treat it as a capacity-first pick that should be inspected on arrival. Note that the 127-52-04 version has a messy listing, and we recommend the 121-52-03 we verified.
If you want a lighter, lower-risk crossover, the UWS EC10473 is the first stop; if you prefer a deep full-depth box, see the DECKED.
Before you buy: confirm the 72-inch length fits your bed width, check the weight against your payload, and inspect the welds and finish when it arrives.
Best Underbody Tool Box for Chevy Silverado 1500
6. Buyers Products 1702305 Black Steel Underbody Truck Tool Box (18 x 18 x 36 in.)
Specifications
Type: Underbody (frame-mounted) box
Material: 14-gauge black steel, T-handle latch
Fitment: Universal frame-mount; Silverado 1500 fitment is not verified
Dimensions: 18 x 18 x 36 inches
Origin: Made in USA
Warranty: See the Buyers Products listing
Rating: About 4.4/5 from 1,300+ Amazon ratings
Today’s Best Deals
View at AmazonReasons to buy
- Does not use any bed space and works with a tonneau cover
- Heavy-gauge 14-gauge steel construction
- Made in the USA
- Large rating count: 1,300+ in the snapshot we saw
Reasons to avoid
- Universal frame-mount: Silverado fit is not verified and often needs custom brackets
- Steel is heavier than aluminum
- Hangs under the truck and is exposed to road spray and ground clearance limits
- Silverado-specific mounting is not listed
The Buyers Products 1702305 is the only underbody box in our list, which makes it the answer to a different question: how do you add storage without losing bed space or fighting a tonneau cover? Because it mounts under the truck, it is not affected by the cover at all. It is built from 14-gauge black steel with a T-handle latch, measures 18 x 18 x 36 inches and is made in the USA.
The strongest evidence for it is volume: snapshots we reviewed showed roughly 4.4 stars from more than 1,300 ratings, a large rating volume. Buyers Products is an established maker of work-truck equipment.
The weakness is fitment. This is a universal frame-mount box, and no Silverado-specific mounting is listed. Depending on your trim and any hitch or suspension changes, you may need brackets, and ground clearance is a legitimate concern if you go off-road or carry a lot of weight. Steel is also heavier than the aluminum boxes above, and it is exposed to road spray.
If you want something that bolts to the bed and has documented Silverado fitment, pick the UWS EC10473.
Before you buy: confirm that the 18 x 18 x 36-inch footprint fits between your frame rails and clears your exhaust, spare tire and hitch, and plan for suitable mounting brackets.

FAQs: Frequently Asked Questions
Recommended Best Deal Products
🛻 Can I use a crossover tool box with a tonneau cover on a Silverado 1500?
Usually not at full length. A crossover box sits above the bed rails, which is the space most tonneau covers need. Owners typically solve this with a wheel-well box such as the SwingCase, an underbody box, or a cover and box combination designed together. If you already own a cover, check the clamp height and lid clearance before you buy any box.
🛻 Will the SwingCase fit my Silverado 1500?
Only if it is a 2019–2026 new-body truck. UnderCover says it does not fit the Silverado 1500 Limited, trucks with the MultiPro tailgate or the CarbonPro bed. Some soft tonneaus with low clamps and hard tonneaus with shock lifts can also interfere. Confirm on the listing’s fitment tool.
🛻 What is the best size of crossover tool box for a Silverado 1500?
Most Silverado owners choose a 69-inch low-profile box, like the UWS EC10473, which is listed for Fleetside Silverado 1500 trucks from 1999 to 2026. A larger saddle, like the Weather Guard 121-52-03 at 72 inches, holds more but weighs about 133 lb. Match the box’s length to your bed’s width and confirm on the listing.
🛻 Are low-profile tool boxes worth it?
For most owners, yes. A low-profile box keeps rear-window visibility better and is easier to reach over. The trade-off is depth. Forum owners describe UWS boxes as low enough to sit on or step over, which is a big part of why we ranked the EC10473 first.
🛻 Why is there no Dee Zee tool box on the list?
Dee Zee boxes missed our rating cutoff of 4.2 stars. The DZ6163NB averages about 3.7 stars from 151 ratings, the DZ8163B about 2.9 stars from 38 ratings and the DZ6163N about 3.3 stars. We would rather leave out a familiar name than recommend a poorly rated one.
🛻 Are truck tool boxes waterproof?
They are weather-resistant, not submersible. UWS lists a MicroSeal gasket, Weather Guard a full weather seal and UnderCover a moisture seal, but none of these sources describes a waterproof rating. If you carry electronics or paper, keep them in a sealed bag inside the box.
Shopping Tips for Finding the Best Tool Box for Chevy Silverado 1500 in 2026
🛒 Verify your exact Silverado generation first
The 2019 redesign changed the bed, and the Silverado 1500 Limited is the carried-over older body. Many boxes list different part numbers by generation, so match model year, bed length and bed type (Fleetside or Stepside) to the listing.
🛒 Decide how you use the bed
If you need the bed floor free, choose a wheel-well or underbody box. If you want one big lockable space, choose a crossover. If you want a deep, full-depth box, look at the DECKED.
🛒 Check tonneau compatibility before you buy
This is the problem competing roundups skip. Over-the-rail boxes and tonneau covers compete for the same space, and soft tonneaus with low clamps or hard tonneaus with shock lifts can still interfere with wheel-well boxes. Check clearances on both products.
🛒 Watch for accessory and trim conflicts
Some trims have bed lighting or a bed inverter that can interfere with wheel-well boxes, and the MultiPro tailgate and CarbonPro bed are outright exclusions on some listings. Confirm these before ordering.
🛒 Read the rating count, not just the stars
A 4.8 from five reviews is weaker evidence than a 4.2 from more than a thousand. Look at the number of ratings and read the most recent critical reviews, especially for weld quality and fit.
