Autospec 4x4 Summit Undertray Toolboxes

We stock the full Autospec 4×4 Summit Series tapered under tray tool box range at our Cardiff workshop in Newcastle. Every toolbox comes as a pair covering both sides of your ute tray and is available in matte black powder coat finish.

Here are the sizes we stock and who each size suits.

600mm and 650mm Undertray Toolboxes

The 600mm and 650mm pairs are the most compact options in the Summit Series range. They suit ute trays where the available undertray space is limited by the wheel arch position or where a minimal profile toolbox is preferred over maximum storage volume. They work well on shorter wheelbase utes and builds where the primary storage sits in a canopy or drawer system with the undertray toolbox providing supplementary secure storage for smaller items.

• Suits: Shorter ute trays, builds where primary storage is elsewhere and owners who want a compact lockable undertray storage option without a large box protruding below the tray.

700mm and 750mm Undertray Toolboxes

The 700mm and 750mm pairs are the most popular mid-range sizes we fit at our Cardiff workshop in Newcastle. They sit in the sweet spot between compact profile and genuine storage capacity. They suit most standard ute trays on popular dual cab platforms including the Toyota HiLux, Ford Ranger, Isuzu D Max and similar models without requiring modification to fit within the undertray clearance.

• Suits: Most popular dual cab utes in the standard tray configuration. Tradies who want secure undertray storage for hand tools, consumables and smaller power tools without the box sitting below the chassis line.

800mm and 850mm Undertray Toolboxes

The 800mm and 850mm pairs step up the storage volume significantly while still fitting within the undertray clearance of most popular ute platforms with standard tray widths. They suit tradies and touring builds that carry more gear and need the additional capacity without moving to a full-length undertray box.

• Suits: Tradies running larger tool sets, builds with more storage requirements and ute owners who want additional capacity without moving to the maximum size options.

00mm and 950mm Undertray Toolboxes

The 900mm and 950mm pairs suit wider tray platforms and builds where maximum undertray storage is the priority. They work particularly well on utes running aftermarket Autospec Summit Series trays which are designed to accommodate the full Summit Series toolbox range at their maximum dimensions.

• Suits: Wider tray platforms, builds running Autospec Summit Series trays, serious tradies who carry maximum gear and owners who want the largest undertray storage option compatible with their specific tray width.

1000mm, 1050mm and 1100mm Undertray Toolboxes

The 1000mm, 1050mm and 1100mm pairs are the largest options in the Summit Series range. They provide maximum undertray storage capacity and suit wide body ute tray builds running aftermarket trays with extended tray width dimensions. These sizes are specifically engineered for the Autospec Summit Series tray system and deliver the maximum possible storage volume in the undertray position. Before purchasing the 1000mm, 1050mm or 1100mm options our team at our Cardiff workshop confirms your specific tray dimensions and undertray clearance to ensure the correct size fits correctly on your build.

• Suits: Wide body tray builds, Autospec Summit Series tray installations and serious work builds that need maximum undertray storage capacity.

Why Tradies and 4WD Owners Choose Autospec Summit Undertray Toolboxes

Tapered Design That Sits Clean Under Your Tray

The Summit Series undertray toolbox uses a tapered profile rather than a straight-sided box. The taper follows the chassis clearance geometry under the tray so the box sits flush and clean rather than protruding below the chassis line or creating a clearance issue with the rear wheels or suspension components.

Australia tradies and 4WD owners who have previously run generic straight-sided undertray boxes and experienced clearance problems immediately notice the difference when they see the tapered Summit Series profile installed at our Cardiff workshop.

Key Lockable for Genuine Tool Security

Every Autospec Summit Series undertray toolbox is key lockable. Tools and equipment lock securely inside the box and stay that way when the vehicle is unattended on a job site or campsite. The locking mechanism is a genuine security feature rather than a clip or latch that pulls open with moderate force.

For Australia tradies who park on job sites through the Hunter Valley and Newcastle region, a properly lockable undertray toolbox is a basic requirement not an optional extra.

Weather and Dust Resistant Construction

The Summit Series undertray toolbox seals against weather and dust intrusion. Coastal salt air near Port Stephens and Nelson Bay, summer storms on the Central Coast, dusty work sites through the Hunter Valley and creek crossings on weekend 4WD trips all expose undertray storage to conditions that deteriorate a poorly sealed toolbox quickly. The Summit Series construction keeps tools and equipment dry and clean regardless of the conditions outside.

Matte Black Powder Coat Finish

The Summit Series matte black powder coat finish integrates cleanly with the broader Autospec Summit Series product range including their aluminium trays, canopies and headboards. If you are building a complete Autospec Summit Series tray and canopy build through our 4WD workshop in Newcastle, the undertray toolboxes match the tray and canopy finish exactly for a clean consistent factory look across the entire build.

Sold in Pairs for Full Tray Coverage

Every Summit Series undertray toolbox comes as a pair covering both the driver side and passenger side of your ute tray in a single purchase. Both sides arrive together, both sides match and both sides install at the same time in a single workshop visit at our Cardiff workshop in Newcastle.

Aluminium Construction for Weight and Durability

Aluminium construction means the Summit Series toolboxes are significantly lighter than steel alternatives of the same size while resisting corrosion in the salt air and wet conditions common around the Newcastle coastline. For a tradie who runs a fully loaded ute daily, every kilogram of accessory weight matters for payload and fuel economy.

Compatible With the Full Autospec Summit Series Build System

The Summit Series undertray toolboxes are engineered to work within the broader Autospec Summit Series build system. If you are planning a complete tray, canopy, toolbox and headboard build through our Cardiff workshop, the Summit Series undertray toolboxes integrate with the tray system dimensions and mounting points as part of a cohesive build rather than a mix of incompatible products from different brands.
