Introducing the Full Beam Duratorque, 1000-1500kg, Gull Wing, for AU Top Hat — a purpose-built trailer suspension engineered for rugged reliability and smoother towing. This is Duratorque, refined for heavier loads and boat-trailer applications, with a gull wing full-beam design that lowers the boat sits position without compromising strength or stability.

Why this Duratorque stands out

• Independent wheel suspension: each wheel is sprung separately by a durable rubber cord system, so road irregularities are managed on a per-wheel basis, reducing sway and improving control on uneven surfaces.
• Full Beam Gull Wing variant: designed specifically for boat trailers, the Gull Wing form lowers the boat’s stance for easier loading and a sleeker trailer profile.
• Corrosion protection you can count on: all components are galvanised or electro zinc plated, delivering long-term resilience in challenging weather and road conditions.
• Built to adapt: available as straight or full-beam units, with options for non-braked, disc-braked, and electric drum-braked hubs to match your braking needs and vehicle setup.
• Made-to-order with clear lead time: this part is manufactured to order with a 6-8 week lead time, ensuring you get a Duratorque tailored to your trailer configuration.

Key specifications and configurations

The Full Beam Duratorque covers carrying capacities from 1000kg up to 2200kg in two-piece and full-beam variants, with 3000kg versions available in full and drop beam formats. For tandem setups, the per-axle capacity reduces by 25% to reflect the load distribution across two axles.

• Single axle / Tandem: when arranged in tandem, each Duratorque’s effective capacity is reduced by 25% (e.g., two 1500kg full-beam units carry 2250kg combined).
• Brakes compatibility: all Duratorques can be fitted with non-braked or braked hubs. Electric drum brakes are offered in 1750kg and 2200kg capacities; other configurations support hydraulic disc brakes.
• Available variants (Straight Beam Type):
• T101046 1000kg – 1500kg (select capacity): Non braked & disc braked
• T101055 1750kg: Non braked & disc braked
• T101051 1750kg: Electric drum braked
• T101052 2200kg: Non braked hubs & disc braked
• T101068 3000kg: Non braked, disc & electric braked

What it means for your trailer

The Duratorque system is a superior suspension solution for trailers of all types, offering a self-contained, easily fitted assembly that keeps each wheel independently tuned to the road. The Gull Wing/full-beam version is especially advantageous for boat trailers, allowing a lower overall boat height while maintaining a robust, safe ride height.

Practical guidance for ordering and installation

• This part is made to order with a 6-8 week lead time. Plan accordingly when scheduling your trailer build or refurbishment.
• When ordering, download and fill out the axle order sheet to specify exact length measurements (C & B) required for your chassis. Hub equipment is ordered separately.
• For tandem configurations, remember the 25% per-axle capacity reduction and ensure the front axle is braked when mounted in tandem for optimal braking balance.
• When mounting, it’s recommended to position the swing arms trailing, keep tyre distance to a minimum (not more than 150mm between tyres), and maintain at least 120mm clearance between the top of the tyres and the mudguards when the Duratorques are new and unloaded.

Who benefits most

Boat trailers, heavy-duty equipment trailers, and any application where a low-profile, highly stable, independently sprung axle is desired will gain from the Full Beam Duratorque Gull Wing setup. It’s ideal for users who prioritize long-term corrosion resistance, modular braking options, and a trailer that sits lower on the road without sacrificing load capacity.

Specification and compatibility details help you choose the right Duratorque for your AU Top Hat chassis. If you’re upgrading or building a trailer that needs dependable, road-ready suspension with flexible braking configurations, the Full Beam Duratorque is engineered to deliver predictable performance and lasting value.
