Hub and Stub 1750kg NB 5x41/2x1/2 S/Line

Meet a rugged, NZ-ready hub solution built to keep trailers rolling with confidence. The Hub and Stub 1750kg Non-Braked 5x41/2x1/2 S/Line is designed to fit Trojan Duratorque and beam axles, and it’s compatible with most NZ-manufactured trailer axles. When you need a reliable replacement or upgrade, this non-braked hub kit delivers steady performance, straightforward installation, and long-term durability.

Compatibility and fit

These non-braked hub kits are purpose-built for Duratorque and beam axles, yet they’re versatile enough to suit a wide range of NZ trailer axles. The 5x4.5" (5 studs with a 4 1/2 inch PCD) configuration covers the most common wheel combinations, ensuring you can reuse or source widely stocked rims and tyres with ease.

Why this hub kit matters

If you’re rebuilding a trailer or replacing worn hubs, the Hub and Stub 1750kg Non-Braked 5x41/2x1/2 S/Line gives you a robust, NZ-focused solution. The 5-stud patterns cover the most common rims, letting you pair with widely stocked tyres and wheels without fuss. The 1750 kg per axle rating ensures you have a strong foundation for typical trailer loads, while the option to bolt-on a rotor later lets you scale up to braking without replacing the entire hub assembly.

Ideal use cases

• Trailer maintenance for builders, farmers, and transport operators who rely on NZ-made axles.
• Replacement hubs for Duratorque or beam axles where a non-braked setup is currently used.
• Custom trailer builds where a common 5x4.5" pattern improves rim compatibility and stock availability.

Practical notes

There are a range of spare parts available for this product, and the kit is designed to be straightforward to service. If you anticipate upgrading to braking later, the bolt-on rotor option provides a seamless path without restarting the build. For accurate fit, refer to the two part-number options above and choose the pattern that matches your wheel studs and PCD.
