The Straight Beam Axle - Tophat Disc - 1750kg - Galvanised from Trojan is built to handle demanding trailer workloads with lasting reliability. Crafted for leaf-spring suspensions, this dedicated axle combines a heavy-duty straight beam with robust tophat disc hubs, delivering straightforward installation, precise alignment, and long-term protection against the elements. This is not a generic part—it’s a tailored, order-to-build solution designed to fit your exact trailer configuration and payload needs.

Why this straight beam axle stands out

• High-capacity, galvanised construction: rated for a 1750 kg gross axle load, the axle uses a galvanised finish to resist rust, salt spray, and weather exposure—ideal for rural, coastal, or farm environments where durability matters.
• Tophat Disc hub design: engineered for strength and ease of service, the Tophat Disc hubs provide solid mounting and reliable bearing alignment, helping you maintain optimal tracking and reduce maintenance over time.
• Tailored to your application: assembled for leaf-spring suspensions and available in 40 mm, 50 mm, or 65 mm square hollow box sections depending on capacity, ensuring the right stiffness and payload handling for your trailer.
• Braked or non-braked options: choose the braking configuration that matches your trailer requirements, helping you optimize stopping power and compliance for your load class.
• Precise fit with C and D measurements: to match your chassis, this axle is specified with key dimensions—C (face-to-face distance between hubs) and D (center-to-center distance from springs mounted position). These measurements ensure smooth installation and accurate wheel alignment.

Beyond raw specs, this axle is designed to streamline assembly and reduce mid-project uncertainties. The galvanised coating minimizes maintenance needs, so you can focus on use rather than upkeep. The straight beam geometry provides predictable load distribution across the axle, contributing to stable handling and reduced wear on wheels and tires over time.

Ideal uses and real-world scenarios

Designed for trailers and utility vehicles that endure regular payloads and varied terrain, the Straight Beam Axle - Tophat Disc - 1750kg - Galvanised excels in:

• Trailers for agricultural equipment, hay handling, and livestock transport where durable, weather-resistant components matter
• Horse floats and general utility trailers that require dependable axle performance with straightforward servicing
• DIY trailer builds where exact mounting spacing and hub compatibility are essential for safe, compliant operation

How this axle compares to typical off-the-shelf options

Rather than a one-size-fits-all part, Trojan’s Straight Beam Axle is a made-to-order solution that emphasizes exact fit and long-term value:

• Customizable based on capacity and spacing (C and D) to align with your chassis plan
• Upgradable galvanised finish for superior corrosion resistance compared with bare-metal or non-coated options
• Tophat Disc hubs designed for dependable mounting and maintenance ease, reducing downtime during inspections and service

Practical ordering and installation notes

This axle is built to order with a lead time of at least six weeks, reflecting its custom nature and the demand for precise specifications.
