Trojan’s Drop Beam Axle - 9" Drum - 1250kg - Galvanised is purpose-built for builders who value precision, longevity, and adaptable suspension configurations. This is a made-to-order axle with a lead time of at least six weeks, ensuring your trailer receives a tailor-made component that fits your exact layout. When you place the order, download and fill out the Axle Order Sheet (Adobe PDF) to capture all essential measurements before production begins.

Why this drop beam axle stands out

• Rigorous load capacity: a 1250 kg axle rating designed for robust trailers and utility applications that regularly carry heavy gear or livestock.
• Drop beam geometry for stability: the drop height (B) can be specified as 60 mm or 90 mm, providing improved ride height, better tire clearance, and enhanced control on uneven surfaces.
• Drum brake compatibility: configured for drum-type braking systems, with the flexibility of choosing braked or non-braked variants as you customise your build.
• Corrosion resistance you can rely on: galvanised finish protects the beam in challenging environments, from coastal work sites to rural jobsites.
• Versatile beam options: available in straight, drop, or Gull Wing configurations to match your trailer’s wheel track and mounting geometry; this product is the drop-beam variant that pairs with leaf-spring suspensions.
• Customizable cross-section: constructed from square hollow box sections in 40 mm, 50 mm, or 65 mm to suit different load paths and ride characteristics.
• Hubs available on request: if you need hubs fitted to your new axle, you can select from compatible hub options during ordering (see related products).
• Precise measurement references: essential dimensions to specify are C (face-to-face hub-to-hub) and D (center-to-center of the spring mounting). For Gull Wing axles, you’ll also provide E (bend depth). For Drop Beam axles, provide B (drop height). These inputs ensure a perfect fit for your trailer.

Who this is for

Ideal for builders of mid-to-heavy-duty trailers, including utility trailers, agricultural trailers, boat trailers, and commercial trailers that run on leaf-spring suspensions. The galvanised finish makes it a solid choice for outdoor, salt-prone, or rugged environments where longevity matters as much as performance.

How it compares and why it matters

Compared with generic straight- or non-custom axles, this Drop Beam Axle offers a tailored drop height, targeted compliance with your C and D measurements, and a finish designed to withstand exposure. The option to choose between drum brake configurations and braked/non-braked variants provides meaningful control over braking response, weight distribution, and overall trailer behavior under load. By specifying your exact dimensions on the Axle Order Sheet, you ensure compatibility with your existing leaf-spring setup, hubs, and wheel track.

Ordering and practical considerations

All drop beam axles are manufactured to order with a minimum lead time of six weeks. Prior to production, you’ll need to download the Axle Order Sheet (Adobe PDF) and provide:

• C: face-to-face distance from outside of one hub to the opposite hub
• D: center-to-center distance of the spring-mounted position
• For Gull Wing axles: E = bend depth (60 mm, 90 mm, or 120 mm)
• For Drop Beam axles: B = drop height (60 mm or 90 mm)

If you plan to fit hubs to your axle, consider selecting hub-compatible options during ordering to streamline installation and ensure proper bolt patterns and offsets.

Tip for installers: align the wheel track to your vehicle’s steering geometry by validating C and D against your existing mounting points, then confirm that the chosen B or E specifications maintain adequate clearance for brake drums, brake lines, and suspension travel under full load.
