The UWS 59" UTV Crossbed Tool Box runs across the front of a side-by-side bed and gives you 3.2ft³ of locked, sealed storage while leaving the rest of the load floor clear. It is 59.75" across, only 12.25" deep and 10.25" tall, which is the shape that makes it work: it takes the strip of bed you were not really using and turns it into somewhere chainsaw kit, straps, fencing tools or a couple of cases can live. This part number is the box on its own, without brackets: UWS builds it to mount with vehicle-specific brackets, but the kit is not in this carton and has to be ordered separately for your machine. The tub is aluminum welded into a single piece in the USA and finished in matte black powder coat, which stays glare-free across the hood. The lid carries UWS's patented RigidCore foam-filled construction so it does not flex or warp, and a MicroSeal gasket runs the lid seam to keep out the water and fine grit that get into everything on a trail machine. A recessed key-operated stainless steel paddle handle locks it. Empty weight is 27.6 lb, and this SKU ships by freight.

Features
3.2ft³ Across the Bed of the Side-by-Side The box runs 59.75" across the UTV bed, stands only 10.25" tall and is just 12.25" deep, so it takes the front strip of the bed and leaves the rest of the load floor clear. UWS rates the interior at 3.2ft³, which is enough for chainsaw kit, tow straps, fencing tools or a couple of rifle cases without eating the space you actually haul in.
Designed for Vehicle-Specific Brackets, Sold Separately This is the bare box. It is built to mount with UWS vehicle-specific brackets, but the bracket kit is not in the carton and has to be ordered separately for your machine. If you want the box and the brackets together, buy the bracketed SKU for your application instead.
Patented RigidCore Lid and MicroSeal Gasket The lid uses the same patented RigidCore construction as UWS's truck boxes, with hardening foam pressed between two aluminum plates so it does not flex or warp, and a MicroSeal gasket runs the lid seam to keep out dust, water and the fine grit that gets into everything on a trail machine.
Welded Aluminum Tub, Powder Coated Matte Black The tub is aluminum, welded into a single piece in the USA, and finished in matte black powder coat. Matte black is the practical choice on a UTV: it does not throw glare back at you across the hood, and the powder coat adds corrosion resistance on top of what aluminum already gives you.
Key-Operated Stainless Steel Paddle Handle A recessed stainless steel paddle handle keeps the box locked and keeps the latch out of the way of shins and cargo. Stainless matters here because a UTV box spends its life wet and muddy.
Ships Freight This SKU ships by freight (LTL), which suits a box this size going to a shop or a yard. UWS also sells the identical box in heavy parcel packaging under a different part number if a freight delivery is awkward for you.
Fitment & Compatibility
Application
Fit
The listed UTV application
● This is the base box with no application-specific bracket kit.
Other side-by-side models
● Only with the correct UWS bracket kit for that machine. The box itself is common across the range; the brackets are what make it vehicle-specific.
ATVs and four-wheelers
✗ No. This is a crossbed box for a side-by-side bed. UWS builds the ATV box for rack mounting.
Pickup truck beds
✗ No. At 59.75" long and 12.25" deep this box is proportioned for a UTV bed and has no truck bed-rail mounting.
Brackets
✗ NOT included with this part number. Order the bracket kit for your machine separately, or buy the bracketed SKU.
Fit guidance: This is a UTV crossbed box. It mounts down in the bed of a side-by-side with vehicle-specific brackets, and it is not a truck bed-rail box: there is nothing on it that clamps to a pickup bed rail, and the 59.75" x 12.25" x 10.25" proportions are wrong for a truck. UWS publishes fitment by machine and model year in its application guide and states only that this SKU suits certain years, so treat the application named here as the starting point and verify the year against UWS before you order. No bracket kit is in this carton.

About UWS
UWS is short for United Welding Services, and the name is the point: every UWS box starts as flat aluminum sheet and is welded into a single-piece tub rather than riveted or folded together. The company builds at its own plant in Perry, Florida, and it has been supplying the truck accessory trade long enough that the diamond plate box with the blue UWS badge is a familiar sight on job sites. UWS is part of the CURT Group, which in turn belongs to Lippert, so behind a fairly specialized Florida welding shop sits a full national parts and warranty network.
Two pieces of engineering separate a UWS box from a generic aluminum one. The first is the patented RigidCore lid: instead of a hollow shell, the lid is a pair of aluminum plates completely filled with a hardening, expanding foam, which sets into a solid structure and stops the lid bending, warping or binding after a few years of being leaned on. The second is the MicroSeal gasket, which lines the entire seam where the lid meets the tub and keeps water, dust, grit and insects out of the box rather than merely slowing them down. Both are backed by a limited lifetime warranty on the box, with one year on the finish and one year on the parts.
Prestige Truck is an authorized UWS dealer. Every box we ship is new, in the original UWS carton, built in the USA, and covered by the full UWS factory warranty.
Frequently Asked Questions
Straight answers on specs, fit and support
Will the UTV-59-MB fit my machine?
This part number is the box on its own, without an application-specific bracket kit, so fitment depends entirely on which UWS bracket kit you pair it with. Check the UWS application guide for your machine and year.
Are the mounting brackets included?
No. This part number is the box only. The mounting brackets and hardware have to be ordered separately for your machine. If you want the box and the brackets in one carton, buy the SKU that is listed for your specific machine instead.
Can I put this in a pickup truck bed?
It is not designed for one. This is a crossbed box proportioned for a side-by-side bed, at 59.75" by 12.25" by 10.25", and it has no truck bed-rail mounting of any kind. For a pickup, look at the UWS chest and crossover boxes instead.
How much will it hold?
UWS rates the interior at 3.2ft³. The tub measures 52" by 11.5", 4.5" deep at the lower section. Those figures come from UWS's own dimension drawing for this part number and match the spec table on the same page.
Will it keep dust and water out?
That is what the MicroSeal gasket is for: it lines the seam where the lid meets the tub and keeps out moisture, dirt, debris and insects. On a trail machine the fine dust is usually the bigger problem, and the gasket is the reason the contents stay clean. It is a sealed box, not a submersible case.
Why are there two part numbers for what looks like the same box?
Because of how it ships. This one goes freight (LTL), which means a truck and a delivery appointment. UWS also sells the identical box in heavy parcel packaging under a separate part number, backed by a damage-free delivery guarantee, if a freight delivery is awkward where you are.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
