Gooseneck & Fifth Wheel Trailers

A Gooseneck trailer is a trailer that uses a ball fitted to the bed of a truck or ute. 

A fifth wheel trailer uses a u-shaped coupling in the tow vehicle bed: very similar to a semi trailer and truck. 

It has the advantage of allowing the tow vehicle to make tight turns using a revolution pin box system. Either type of trailer can be built in any length and weight capacity. Trailers over 4500kg will need air brakes fitting to tow vehicle and trailer.

Race Trailers

Our typical race car trailer can be built to any length / width / height. All are built to our stylish low sleek design. Any number of features can be included. 

The width between the internal mudguards can be 2020mm maximum. Wider cars may need ramps over mudguards. 

Horse Floats

We can build cost effective straight load floats and 2/3/4 angle load floats.
