Gull Wing Axle - Disc Braked - 1500kg - Bare Metal is Trojan’s purpose-built trailer axle engineered for heavy-duty leaf-spring suspensions. This is a made-to-order component with a minimum lead time of six weeks, ensuring you get a bespoke solution that fits your trailer’s exact geometry and performance needs.

Designed to balance strength, longevity, and precise fit, this gull wing beam axle is offered in multiple box-section options and finishes. The disc-braked variant delivers dependable stopping power for heavier loads, with the flexibility to tailor the axle to your setup. All axles can be supplied either galvanised or in bare metal form, giving you the choice of factory protection or a finish you prefer.

Why choose a Gull Wing Disc Braked Axle?

• Durable gull wing design to accommodate specific mounting and clearance requirements while maintaining robust load paths for stability.
• Disc braking provides reliable, consistent stopping performance across a range of trailer weights, reducing wear on wheels and tires over time.
• Made to order with precise geometry: you specify C, D, and E measurements to ensure correct hub alignment, spring mounting, and bend depth.
• Beam options tuned to capacity: 40 mm, 50 mm, or 65 mm square hollow box sections—chosen based on the required strength and stiffness.
• Finish choice to suit your project: galvanised for corrosion resistance or bare metal for on-site finishing.
• Hubs can be fitted to your new axle on request, making installation simpler and ensuring compatibility with your existing brake lines and hubs.

Who this is for and practical use cases

• For trailer builders and operators who require a dependable, heavy-duty disc-braked axle with precise geometry tailored to their frame and suspension configuration.
• Ideal for projects where spring mounting points, hub spacing, and bend depth directly impact alignment, braking performance, and load distribution.
• Perfect for custom or restored trailers where standard off-the-shelf axles don’t meet the clearance or mounting constraints.
• Suitable for both new builds and mid-life trailer upgrades where a robust, easily finishable bare-metal option is preferred.

How to order and what to provide

• Download and complete the Axle Order Sheet (Adobe PDF) before placing the order, ensuring you specify C, D, and E precisely.
• Indicate the required capacity (1500 kg) and whether you want galvanised or bare metal finish.
• Specify whether you want a disc-braked setup and if hubs should be fitted to the axle at installation.
• If you’re unsure about the exact bend depth for the gull wing, refer to the E-depth options (60 mm, 90 mm, 120 mm) and select the value that aligns with your trailer’s frame geometry.
• After ordering, you’ll receive guidance on hub compatibility and any ancillary components needed for a complete axle assembly.
