Designed for heavy-duty trailer builds, the Drop Beam Axle - Disc Braked - 1750kg - Galvanised combines robust structural design with reliable braking and long-lasting protection against the elements. Built to order, this galvanised axle is ready to handle demanding loads while resisting corrosion in outdoor environments.

Key features

• Nominal capacity: 1750 kg, making it suitable for midsize to heavy trailer applications
• Disc braking system for superior stopping power and fade resistance under load
• Galvanised finish for enhanced durability and outdoor longevity
• Available as straight beam, drop beam, or gull wing configurations to match your suspension geometry
• Braked and non-braked variants to suit different trailer requirements
• Beam options include 40 mm, 50 mm, or 65 mm square hollow box sections, chosen by capacity and application
• Made to order with a lead time of at least 6 weeks

Why this drop beam design matters

The drop beam configuration lowers the axle’s ride height, increasing ground clearance for difficult terrains and preventing wheel arch contact on uneven surfaces. For trailers carrying tall payloads or operating on rough roads, the drop in height (B) can be set to 60 mm or 90 mm to balance stability with clearance.

Measurement guidance for precise fit

To ensure a perfect fit, Trojan builds each axle to your measurements. You’ll need to provide:

• C — face-to-face measurement from the outside face of one hub to the opposite hub
• D — center-to-center distance of the spring mounting position
• B — the required height of the drop (60 mm or 90 mm for drop beams)
• For Gull Wing axles: E — depth of the bend (60 mm, 90 mm, or 120 mm)

All measurements are captured on the Axle Order Sheet. This part is made to order, so download the sheet, complete the fields, and return it with your order to ensure accurate fabrication.

Hub options and compatibility

If you need hubs fitted to your new axle, Trojan offers hub assemblies as a complementary option. For customers who want a turnkey installation, consider selecting hubs during the ordering process so the axle arrives ready to bolt onto your trailer frame.

Materials, finish, and longevity

All drop beam axles can be supplied galvanised or bare metal, depending on your environmental exposure and corrosion resistance needs. The galvanised finish is particularly advantageous for trailers used outdoors, salt-prone environments, or equipment subjected to frequent washdowns.

Who this is ideal for

Ideal for trailer builders, agricultural trailers, utility trailers, and commercial equipment trailers that rely on a robust, precisely configured axle with dependable disc braking. It’s also a strong choice for bespoke trailers where custom geometry is essential to achieve the desired handling and stability.

Order with confidence

Because these axles are manufactured to firm orders, lead times begin at a minimum of six weeks. Start by downloading the Axle Order Sheet (Adobe PDF), fill in the required measurements (C, D, B, and potentially E for Gull Wing), and specify your galvanised option. If you need hubs fitted, indicate so during checkout and reference the related products below. This ensures you receive a drop beam axle that fits your trailer frame precisely and performs reliably on the road or worksite.
