What’s included and how it works

The kit comprises a pair of hubs with a 1500 KG GVM rating for a single axle, paired with a set of 38mm round stub axles that include a built-in caliper mount. Calipers are sold separately, so you can tailor the braking hardware to your preferred caliper style and pad choice. A full cast disc or a fitted bolt-on disc (cast iron or stainless) is supplied in the range, ensuring you can select the disc material best suited to your operating conditions and corrosion exposure.

Ideal use cases and who benefits most

• Trailer operators using Trojan Duratorque or beam axles who want a robust, high-GVM braking hub solution.
• NZ-based fleet owners seeking versatile hub kits that accommodate a variety of common wheel stud patterns and rim sizes.
• Owners needing durable discs (cast iron or stainless) for different environments—from coastal salt exposure to off-road or heavy-duty use.

Practical tips and maintenance notes

When selecting a disc configuration, consider exposure to corrosive environments and wheel availability. Stainless steel bolt-on discs offer superior corrosion resistance, while cast iron discs provide reliable stopping power at a typically lower cost. If you’re mixing components, verify your wheel stud pattern and PCD align with one of the listed configurations to ensure proper mounting and safe braking performance. Spare parts are available, and your order ships within 4–7 days from the supplier, so you can plan maintenance or replacements with confidence.
