Truck Bed Storage Boxes
Weatherproof, lockable cargo cases built to live in a pickup bed — roto-molded boxes from 50 to 175 liters, plus low-profile rack-mount cases that keep your load height down.
Shop SRX Cargo Cases Low-Profile Rack CasesAn Eylar® truck bed storage box is built for the conditions a pickup bed actually delivers: driving rain at highway speed, dust that works into every seam, cargo shifting on washboard roads, and parking lots where anything visible and unlocked walks away. Every case on this page seals with a weatherproof gasket, locks shut, and is engineered to be tied down, stacked, or rack-mounted — so your tools, recovery gear, and camp kit ride protected from the job site to the trailhead.
Why Your Truck Bed Needs a Dedicated Storage Box
- Gasket-sealed lids — keep rain, mud, and fine dust out of your gear in an open bed
- Lockable security — integrated locking points and padlock-ready hasps deter theft at trailheads, campsites, and job sites
- Stackable, modular design — build a cargo system instead of a pile of loose totes
- No rust, no corrosion — roto-molded polymer shells shrug off salt spray, road brine, and years of sun
SRX Series — Roto-Molded Truck Bed Cargo Cases
The Eylar SRX series is the core of our truck bed storage lineup. Each case is molded in one seamless piece from impact-grade LLDPE — no welds, seams, or fasteners to split or leak. The shell flexes under load instead of cracking, stays flexible in cold weather, and won't rust, corrode, or oxidize on wet and salt-air trails. Gasket-sealed lids keep the weather out; integrated locking points keep your kit secure; the stackable geometry turns a truck bed into organized, modular storage.

When the space over your bed is spoken for — bed racks, crossbars, a rooftop tent overhead — the Eylar low-profile cargo case line keeps long gear in a slim, lockable footprint. These hard-shell cases run just 6.12" to 6.3" tall on the 38"–48" models, with a reinforced polypropylene body, IP67 waterproof and dustproof protection, TSA-approved padlock hasps, three layers of customizable foam, and reinforced wheels. Mount them on truck bed slats, slide them under a rack platform, or stack them in a trailer bay.
Which Truck Bed Storage Box Is Right for You?
Start with what stays in the bed permanently. A daily-carry tool and emergency kit fits an SRX-50; a serious recovery setup with traction boards wants the SRX-90 or SRX-110; a family running multi-day trips should look at the SRX-175 or a stacked pair of smaller cases. For long-handle tools, awnings, and recovery boards, the low-profile 38"–53" cases carry length without eating vertical space. All of them are sold with free US shipping and 30-day returns.
Truck Bed Storage Box FAQs
What should I look for in a truck bed storage box?
Three things: a gasket-sealed lid (an open bed is a wet, dusty place), real locking points, and a shell that survives impacts and sun. Roto-molded LLDPE flexes instead of cracking, won't rust or corrode, and holds up to years of UV exposure.
Are Eylar truck bed storage boxes waterproof?
SRX cargo cases are weatherproof, with gasket-sealed lids that keep out rain, mud, and dust. The low-profile rack cases carry IP67 waterproof and dustproof protection with a rubber gasket lining.
Can I lock a truck bed storage box?
Yes. SRX cases include integrated locking points for padlocks, and the low-profile cases have two padlock-adaptable hasps that meet TSA requirements for travel.
What size storage box fits a truck bed?
Measure your usable bed floor between the wheel wells, then work backwards. SRX cases run 50 to 175 liters and are stackable, so two smaller cases often beat one large one. The low-profile line runs 38" to 53" long for full-length gear.
