TrailCore Tray & Toolbox Features
Slam Latch Side Boards
Fiddly anti-luce fasteners or over-centre latches on Tray sideboard can be frustrating to work with - the TrailCore Tray slam latch sideboard catches are quick and easy to use, and remove any externally protruding features giving a sleek and modern look.
Quick-Release Side Boards
Sometimes you want to carry a load without the sideboards on, but R clips can be fiddly to use and easy to lose causing your sideboards to fall off down the track. The TrailCore Tray Innovative hinge mechanism allows you to quickly remove the side board if needed, and then install them back on in a few seconds without any moving parts or fastners!
Huge Undertray Drawer
Small cases and parts are vulnerable to theft on the Tray, so secure storage is a must. The TrailCore boasts the largest lockable undertray drawer on the market, meaning you can store a huge amount of gear down low and out of the way! Better still, its long enough to take your side boards if you take them off and is compatible with central locking.
Dimensions:
Double Cab: 820mm Wide x 1700mm Long
Extra Cab: 820mm Wide x 2000mm Long
Single Cab: 820mm Wide x 1700mm Long
Strong Bones
Reinforced with extruded braces along the front, rear, and ceiling, giving it incredible strength and durability.
This makes it resistant to bending, even under heavy loads or rough conditions. It's strength-to-weight ratio is unbeatable, offering toughness without the extra weight.
If you're tired of flimsy trays and need something built to last, the TrailCore Tray is the real deal.
Full-Perimeter Seal & Rain Channel
Whether you're out on a dusty 4WD track or in the rain, a leak can damage tools or adventure gear.
This is not only costly, but it can also hinder your ability to get stuff done.
The TrailCore Service Body has minimal joints, no exposed rivets piercing the skin and full seals on all of the doors so your gear will be dry and free of dust.
The underfloor drawer is now inside the main body, so is not exposed to the elements.
T-Tracks Everywhere!
The whole interior mounting system is assembled using T-Tracks, making it easy for you to adjust and add accessories as needed.
This flexibility ensures you won’t outgrow your setup, no matter how your needs evolve.
Concealed Wiring Routing
On some canopies, the electrical wiring just gets left hanging loose. The TrailCore features hidden cable routing, so you can tuck everything away and keep your electrics safe from damage.
Internal Tie-Down Points
Strapping loads over your side boards can mean that the sideboards can get damaged and the load becomes loose. The TrailCore Tray comes standard with 6x internal recessed Heavy Duty tie down rings to give you extremely strong structural tie down points at a low angle. They also work well with a load that is lower than the height of your sideboards.
Infil Panels
Often a Tray will have areas of the underbody exposed either side of the mudguards. This leaves the vehicle looking unfinished and out of shape.
TheTrailCore Tray comes standard with infill panels to suit the contours of the ute it's going on. These are all model-specific and will cover up any exposed areas under the body, enhancing the overall style.
Lightweight But Strong
The TrailCore Tray is lightweight so you can take more gear with you without exceeding your payload. This has been achieved using the aluminium extrusion design which requires less material to achieve a strength rating that exceeds a lot of Aluminium Tray designs.
Keeping your weight down is not only important for driver safety, but it also reduces fuel consumption and improves offroad dynamics.
Multiple Door Configurations
Hard-working ute owners require efficient ute setups in order to get stuff done, enjoy life's adventures!
Choose from a range of door options including:
- Standard Door
- Split Door / Work Bench
- Roadside Safety Door
Built with Strong Bones
Engineered for zero failure and maximum payload is the standard every product has to meet before it ships.
Thermal testing, cycle testing, load rating, and shake testing - that's the baseline. Then we take it further. Strong Bones extreme testing pushes every product to its limits, so you never have to find them yourself.
That's the confidence behind our 5-year warranty. If it's not right, we'll make it right - no questions asked.
