TROJAN 2x Galvanised M12 Trailer Spring U-Bolts – 110mm Arm, 51mm Wide
These heavy-duty U-bolts are purpose-built for securing round trailer axles within your trailer’s suspension system. Each U-bolt features a strong 12mm thread diameter, fully galvanised finish for long-lasting corrosion resistance, and is sized at 51mm internal width and 110mm arm length.
They are ideal for:
- Mounting 50mm round axles to trailer leaf springs
- Replacements during axle or suspension repairs
- DIY trailer builds or refurbishments
- Boat trailers, utility trailers, box trailers, or caravans
The galvanised coating not only resists rust in harsh environments, including coastal or wet conditions, but also extends the lifespan of your trailer’s structural integrity. This makes them especially suitable for Australian conditions where weather extremes demand durable components.
Each pack includes 4 U-bolts, designed for secure and even clamping pressure. Simply pair them with suitable fish plates and nyloc nuts (not included unless specified) to ensure a rock-solid hold on your axle assemblies.
