Aluminium Truck Body Systems

For a strong and good-looking truck body

The smarter way to build your truck or trailer body

Looking for a truck or trailer body that’s strong, lightweight and built to last? The Multilock System, developed by Boss Motorbodies Ltd, is designed to do just that. Using expertly crafted aluminium extrusions that lock together seamlessly, Multilock delivers a sleek, reliable finish every time.

Whether you need a body that’s big, small, or somewhere in between, Multilock gives you the flexibility, durability and smart design that puts it ahead of the rest.

Multilock Features

When you’re investing in a truck or trailer body, you want something that not only performs exceptionally but also makes your business more efficient, cost-effective, and professional.

That’s exactly what the Multilock Truck Body System delivers. Here’s how it can benefit you:

Multilock bodies are built with tough extruded aluminium wall panels and 200mm internal ribs, offering superior resistance to dents and punctures.
 
What this means for you:
 
  • Fewer panel repairs and reduced maintenance costs
  • A cleaner, well-kept appearance that reflects positively on your business
  • Longer service life – your truck body will stay looking good and performing well for years

Multilock bodies are significantly lighter than traditional steel-frame builds. By removing the need for steel sub-frames and wall structures, we help you cut down on vehicle tare weight.

What this means for you:

  • Lower fuel consumption = lower running costs
  • Reduced engine wear, prolonging the life of your vehicle
  • Potential savings on Road User Charges (RUC)
  • More usable payload – so you can carry more without exceeding weight limits

Made primarily from aluminium – one of the most abundant and recyclable metals on Earth – Multilock is a forward-thinking, eco-conscious solution. It can even be built entirely without timber.A greener choice that aligns with modern sustainability goals

  • Reduce your reliance on timber materials as forests become increasingly depleted
  • Enjoy peace of mind knowing your truck body can be recycled at the end of its lifespan

Multilock suits all types of vehicle builds, from small utility units to large freight bodies.

What this means for you:

  • A consistent, reliable system across your entire fleet
  • Flexibility to customise vehicle bodies for different needs
  • Scalable solutions that grow with your business

Multilock makes it easy to build wide, strong, and lightweight container-style side doors, including vertical opening options.

What this means for you:

  • Easy access for drivers and loading teams
  • Reduced wear on hinges and improved ease of use
  • Faster, more efficient loading and unloading

Multilock features smooth wall panels and rounded corners for a sleek, contemporary look. You can choose natural aluminium or a painted finish.

What this means for you:

  • A more professional image for your business
  • A clean, streamlined appearance across your fleet

With fasteners only at the top and bottom of the walls, the surface remains smooth and uninterrupted.

What this means for you:

  • Easier application of decals and signage
  • A polished, high-impact canvas for branding and advertising
  • No visible rivets to disrupt the visual appeal

Multilock panels are made from high-grade aluminium extrusions, not thin wall linings. Damaged panels can be replaced individually.

What this means for you:

  • Lower repair costs and faster turnaround
  • Minimal downtime – keep your vehicles on the road
  • Better long-term value from your investment
