The Full Beam Duratorque Gull Wing is a purpose-built, heavy-duty suspension system designed to elevate trailer performance to a new standard. Rated 1000-1500kg per axle, this model is crafted to handle demanding loads while delivering a smoother, more controlled ride. It’s a made-to-order solution with a practical 6-8 week lead time, ensuring you get the exact dimensions and mounting fit for your trailer. When ordering, download and complete the axle order sheet, and note that hub equipment is ordered separately.

What makes the Duratorque exceptional

• Independent wheel suspension: Each wheel is sprung independently because the two sides aren’t connected, delivering a smoother ride, improved load distribution, and better handling on uneven surfaces.
• Robust, corrosion-resistant construction: All Duratorque components are galvanised or electro zinc plated to withstand trailer environments and coastal conditions.
• Versatile capacity and configurations: Carrying capacities range from 1000kg to 2200kg for two-piece and full-beam variants, plus a 3000kg option in full or drop beam. The Gull Wing full-beam variant is specifically designed to sit the boat lower on the trailer for easier loading and a sleeker profile.
• Two-piece or full-beam options: Choose a two-piece unit to fit any chassis width, or opt for a full-beam Duratorque tailored to higher capacities and a lower boat profile. Gull Wing full beams are ideal for boat trailers where lowering the load height matters.
• Braking versatility: Duratorques can be fitted with non-braked hubs or disc-braked hubs. Electric drum braking is available for higher capacities (1750kg and 2200kg), and a 3000kg variant supports non-braked, disc, or electric braking configurations.
• Tandem configurations with clarity: When mounting in tandem, the carrying capacity per Duratorque is reduced by 25% (e.g., two 1500kg full-beam units yield a combined 2250kg). Plan accordingly for twin-axle setups.

Why boat trailers and low-profile setups benefit

The Gull Wing full-beam design lowers the boat’s resting height on the trailer, improving stability during loading and transport while keeping ground clearance intact. For best results, mount the Duratorque with the swing arms trailing and minimize tyre distance on twin-axle configurations—aim for no more than 150mm between tyres. This configuration helps balance load distribution and enhances trailer dynamics on the road.

Practical ordering and installation notes

• Lead time: This part is made to order with a 6-8 week lead time, so plan for production and shipping accordingly.
• Ordering process: Download the Axle Order Sheet (Adobe PDF) and fill it out to ensure correct capacity and mounting details. Hub equipment is ordered separately.
• Dimensions to provide: When ordering full-beam Duratorques, supply the required length measurements C & B as shown in the accompanying diagram to guarantee proper fit.
• Documentation: Access the Positive Camber Bend information and other general guidance via the included PDFs to ensure correct alignment and installation.

Electrical braking and higher-capacity options: Electric drum brakes are available on 1750kg and 2200kg Duratorques, with a 3000kg version offering non-braked, disc, or electric-braked configurations. If you’re upgrading an existing setup or specifying a new one for a heavier load, these options help you tailor braking performance to your trailer weight and towing needs.

Ideal users and use cases

• Boat trailer owners seeking a lower, stable load profile without compromising clearance or loading ease.
• Pro builders or DIY trailer enthusiasts needing a robust, corrosion-resistant suspension that’s easy to install and service.
• Deliveries and transport operators who require predictable handling under varying road conditions and weather.

With Duratorque, you’re choosing a self-contained, easily installed suspension that provides independent wheel response, enhanced durability, and a low-profile option for boat-trailer setups. It’s a thoughtful upgrade for trailers that demand reliability, longevity, and better ride characteristics without the complexity of traditional leaf-spring systems.
