Introducing the Full Beam Duratorque Gull-Wing Beam Axle 2200kg — a purpose-built suspension system engineered for demanding trailer work, especially boat trailers. With its independent wheel design, corrosion-ready construction, and factory-ready versatility, this is a transformatively smoother, more reliable towing experience.

Why the Duratorque Gull-Wing Stands Apart

• Independent wheel suspension — each side is sprung separately, so irregular surfaces or heavy waves won’t throw the entire trailer off balance. This translates to better handling and consistent tire wear.
• Self-contained, plug-and-play fit — specially formulated rubber cords act as the springing medium, and the Duratorque assembly is designed for straightforward installation to the trailer chassis.
• Durable, corrosion-resistant construction — all components are galvanised or electro-zinc plated, giving long service life in harsh marine and roadside environments.
• Bolt-in replaceable stub axle (1000–1750 versions) — since 2011, these’ve made field maintenance simpler and faster, reducing downtime on the water or the road.
• Modular capacities and configurations — available in 1000kg, 1500kg, 1750kg, 2200kg (two-piece and full-beam); 3000kg in full and drop beam. Hubs and stubs are not included, and there’s a clear path to the right setup for your trailer size.

Capacities and Compatibility

• Single-axle capacities: 1000kg, 1500kg, 1750kg, 2200kg (two-piece and full-beam types).
• Heavy-duty option: 3000kg available in full and drop beam configurations.
• Tandem installations require a 25% reduction in total capacity (e.g., two 1500kg full-beam Duratorques carry 2250kg).
• Braking options: compatible with non-braked hubs or braked hubs, including hydraulic disc brakes (1500kg, 1750kg, 2200kg, 3000kg), electric drum brakes (1500kg, 1750kg, 2200kg), and hydraulic drum brakes (1250kg).

Key Measurements and Fitment

Duratorque full-beam assemblies are built to order and require precise length measurement—A, B, and C—as shown in the accompanying diagrams. When ordering, specify the exact length to ensure a perfect fit for your trailer frame. Important spacing notes to maximize performance and clearance:

• For tandem mounting, keep the tyre distance to 150mm or less.
• New, unloaded Duratorques should have at least 120mm clearance between the top of the tyres and the mudguards.
• Front axle on a tandem setup should be braked.
• Pack weight is 42kg per unit.
• Hubs and stubs are not included; products are built to order with no spare parts supplied.

Applications and Use Cases

Designed with boat trailers in mind, the Duratorque Gull-Wing beam axle excels in marine environments where corrosion resistance and dependable suspension matter most. Its independent-suspension design helps boats stay level on rough ramps and uneven ramps, while the robust galvanised finish resists salt spray and road grime between trips. It’s equally at home on utility trailers, small commercial trailers, or any setup where a durable, semi-custom beam axle is a priority.

What You Get and How It Compares

• Custom-length full-beam Duratorques tailored to your trailer’s A, B, and C measurements — a precise fit reduces installation time and ensures optimal handling.
• Not sold as a pair; each unit carries its own capacity rating and can be paired with compatible hubs and brakes for the exact stopping power you require.
• Compared to generic suspension options, the Duratorque system offers independent wheel travel, easier maintenance with bolt-in stub axles, and superior corrosion protection — translating to longer service life and more predictable towing behavior.

Practical Tips for Installation and Maintenance

• Plan for trailing swing arms during mounting to optimize clearance and performance over load cycles.
• Choose the braking configuration that matches your towing needs and the axle’s capacity—disc or drum, electro-mechanical or hydraulic—without exceeding the specified load limits.
• Account for the full-beam versus two-piece configuration when budgeting space and mounting hardware on your trailer frame.

Ready to upgrade to a reliable, marine-ready suspension that’s built to last? The Full Beam Duratorque Gull-Wing 2200kg is built to order for a tailored fit, offers robust corrosion protection, and delivers consistent, independent wheel performance on every trip.
