8×5 High Side Box Trailer – More Depth, More Versatility

Need more space for taller loads? This high side box trailer gives you that extra cubic space while staying easy to tow and store. Designed for users who want a practical upgrade from standard trailers, this 8×5 single axle trailer offers 920kg load capacity and more usable space. This high sided trailer stands out with 425mm high sides, offering significantly more bed depth than the standard 300mm walls. This extra height makes a big difference when you’re transporting loose materials, bulky items, or gear that requires added containment. Additionally, this 8×5 high side box trailer is fully welded and fully hot dip galvanised in molten zinc. This process coats the trailer inside and out, providing complete protection from rust and corrosion. It’s made to handle Australian weather, rough roads, and years of use. Another excellent feature of our galvanised trailers is that all the electrical wiring runs inside the chassis tubes. This design shields the wires from water, debris, and physical damage, ensuring long-term durability and added peace of mind.

 Trustindex verifies that the original source of the review is Google. I contacted Farzad from TGT before coming down from NSW, advised him what I was looking for and he emailed through three professional itemised quotes. I selected an 8x5 tandem trailer with ramp which I am very happy with. Other people have commented on the quality of my trailer. I would highly recommend Farzad and his father from TGT for customer service, price and workmanship.

 Trustindex verifies that the original source of the review is Google. Purchased my 7x5 trailer a few years ago and done over 5,000 kms. It’s  a heavy duty trailer and has been great - towed everything with ease with no issues. The quality is evident - long drawbar, heavy duty metal, rated chains,  strong clips, light truck tyres and wheels.  TGT is a family business - the owner and son build the trailers. I have been back a few times for a service and spare parts. Have always been helpful and friendly and gone above expectations on service. Highly recommended!
