Duratorque is a superior suspension system that is suitable for fitment to and use on all types of trailers. Using specially formulated rubber cords as a springing medium, Duratorques are totally self-contained and easily fitted to the trailer chassis. Because the two sides are not connected, each wheel is independently sprung. All Duratorque components are either galvanised or electro zinc plated for protection against corrosion. 

Carrying capacities for Duratorques are 1000kg, 1500kg, 1750kg to 2200kg in both two piece and full beam types and 3000kg version in full and drop beam. These capacities are for single axle applications. When mounted in tandem the capacity must be reduced by 25% i.e. two 1500kgfull beam Duratorques will carry 2250kg. Note that Duratorque half axles are each labelled with the total capacity per pair, not each side. All Duratorques are able to be fitted with non braked or braked hubs. These brakes can be hydraulic disc, 1500kg, 1750kg, 2200kg & 3000kg capacities.

Electric drum brakes in 1500kg, 1750kg & 2200kg capacities and hydraulic drum brakes in 1250kg capacity. Available as two piece units which will fit any chassis width and are available as ex-stock or full beam or one piece units which are manufactured to the customers specifications. Full beams are also available in a gull wing form for fitment to boat trailers allowing the boat to sit lower on the trailer. It is recommended that Duratorques be mounted to the trailer with the swing arms trailing. When mounted in tandem the distance between the tyres be kept to a minimum and should not exceed 150mm. The distance between the top of the tyres and the mudguards when the Duratorques are new and unloaded should be at least 120mm. When mounted in tandem the front axle should be braked. When ordering full beam Duratorques the customer is to supply certain information.
