Trojan’s Drop Beam Axle - 9" Drum - 1750kg - Bare Metal is a purpose-built, leaf-spring compatible axle designed for exacting trailer builds. This is a made-to-order component, with a lead time of at least six weeks, ensuring your axle is tailored to your precise geometry and mounting needs. When you order, you’ll download and complete the Axle Order Sheet to capture your exact measurements and finish preferences. If you need hubs fitted to the new axle, this option is available as a related product.

Key specifications and what makes it unique

• Capacity: 1750 kg gross axle weight rating, paired with a 9" drum braking system (braked or non-braked options available).
• Drop beam geometry: B specifies the required drop height with choices of 60 mm or 90 mm, enabling compatibility with your trailer’s underside clearance and suspension layout.
• Finish options: Bare metal or galvanised finishes to suit exposure, corrosion resistance needs, and service life expectations.
• Beam construction: Available in 40 mm, 50 mm, or 65 mm square hollow box sections, chosen to match load requirements and mounting points.
• Suspension compatibility: Designed for leaf spring suspensions and offered in straight beam, drop beam, and gull wing configurations to fit a range of chassis designs.
• Measurement requirements: Precise fit relies on C (face-to-face hub measurement) and D (center-to-center spring mount). Gull Wing variants also require E (bend depth). For drop beams, C and D are required plus B (drop height). Values can be 60 mm or 90 mm for B, and the bend depths for gull wings can be 60, 90, or 120 mm.
• Made-to-order process: Each axle is built to your specifications after you submit the Axle Order Sheet, with the specified lead time applied to production.
• Hub fittings: If you want hubs attached to the axle upon delivery, you can choose hub fittings as a related product option.

Practical use cases and who benefits most

This Drop Beam Axle is ideal for custom trailer projects where precise geometry matters—whether you’re building a heavy-duty utility trailer, a work trailer, or a specialty caravan. It’s particularly well-suited for configurations that require a defined drop height (B) or specific bend depths (E) to accommodate chassis clearance and suspension geometry. By specifying C, D, and, if applicable, B and E, you get an axle that aligns with your existing leaf springs and hub positions, reducing install time and field adjustments.

Why choose this over standard off-the-shelf axles

Unlike generic options, this is a fully customizable axle designed to your exact measurements and finish preferences. The ability to select the beam size (40/50/65 mm), the drop height (B), bend depth (E for Gull Wing), and the finish (bare metal or galvanised) means you can optimize handling, mounting points, and durability for your specific trailer build. The made-to-order approach minimizes the risk of misalignment and unnecessary modification on-site.

How to order and practical tips

• Download and complete the Axle Order Sheet before placing your order to capture C, D, and, if applicable, B and E specifications.
• Be prepared to specify whether you need a braked or non-braked drum configuration, and your preferred finish (bare metal or galvanised).
• Decide if you want hubs fitted at delivery and consider related product options for hub assembly.
• Remember the lead time: this part is built to order, with a minimum six-week production window from final specification acceptance.

In short, the Drop Beam Axle - 9" Drum - 1750kg - Bare Metal from Trojan is a tailored, high-integrity solution for builders who demand exacting dimensional accuracy and durable performance in leaf-spring trailer applications. It’s not off-the-shelf—it’s designed around your project, so you can trust the axle to integrate seamlessly with your spring mounts, hubs, and chassis geometry from day one.
