Description

This 1,750 kg straight trailer axle is built for medium to heavy-duty trailers requiring hydraulic disc brakes and corrosion-resistant components. It includes stainless-steel hubs (5x114.3" PCD), stainless-steel calipers, and a hot dip galvanised 50x50 mm box section beam. The thick-walled, hollow straight beam offers a comparably strong yet lighter alternative to solid axles. Hubs are supplied pre-fitted for faster setup. The axle is fabricated to match your supplied dimensions, making it suitable for both custom and standard builds.

FAQs

Q: What are the advantages of using box section beams for axles?

A: Box section beams (hollow tube axles) offer significant weight savings without compromising strength for most applications. Their lighter construction allows for increased payload capacity, easier handling during installation, and faster fabrication turnaround. They also allow for easy customisation, making them a flexible choice for trailer builders.

Q: What braking system is needed to operate the hydraulic disc brakes?

A: This set can be used with a hydraulic override coupling fitted to the trailer drawbar. You may also opt to install an electric-over-hydraulic kit if you prefer to have more braking options, and if you want the ability to control the brake from inside the towing vehicle.

Our HydroBrake EOH actuator and controller kits are excellent options. Please visit this page to learn more:

Q: Does the axle include brake pads?

A: Yes. The stainless steel calipers are supplied complete with brake pads fitted. Replacement pads are available separately.
