Trojan Hub And Stub Kits 4x4 39mm SA WeldIn NonBraked Upgrade For HeavyDuty Trailers

Engineered for rugged reliability in 4x4 trailers and heavy-duty equipment, the Hub and Stub Kits deliver a weld-ready, non-braked hub solution designed to be welded to your axle tube for a solid, simple upgrade or retrofit. This 4x4 hub-and-stub kit aligns with the needs of workhorse applications where strength and versatility matter, offering a robust platform that supports common wheel configurations while maintaining straightforward installation.

Why this hub kit stands out

• Weld-ready stub axle: Each kit features a stub axle designed to be welded to your axle tube, providing a strong, permanent hub connection suitable for demanding use.
• High GVM rating: Rated at 1500 kg gross vehicle mass for a single axle (based on a pair of hubs), making it a solid choice for trailers and light industrial vehicles that carry heavier loads.
• Extensive stud-pattern coverage: The range includes multiple wheel stud patterns to fit the most common wheel sizes. The most common configuration is five studs with a 4.5-inch PCD, which matches many stocked rims and tyres.
• Non-braked design: This kit is non-braked and cannot be fitted with a bolt-on disc rotor—ideal for applications where braking hardware is handled separately or where drums or alternative braking solutions are used.
• Variety of configurations: Available in several patterns to suit different wheel studs and flange sizes, with flange diameters chosen to accommodate a wide range of rims while preserving fit and alignment.
• Durable materials: Stub axles made from 1045 medium-tensile steel to AS1442 standard, engineered for reliability under load and road use.
• Practical pack details: Pack weight around 9 kg, with spare parts available and assembly instructions (Adobe PDF) to guide installation and maintenance.

What’s included and how it fits your setup

Designed as part of the 160HUB family, these hub kits are suitable for 4x4 configurations with a 1/4 inch to 7/16 inch wheel stud fit and a 160 mm flange interface. The range covers patterns from 100 mm to 155 mm PCD in common configurations, ensuring you can match your existing rims and tyres. The inclusions and compatibility are tailored for users who want a reliable, weld-in hub solution without integrated braking hardware.

Installation, maintenance and practical tips

• Before welding, verify your axle tube dimensions and confirm the exact stud pattern and flange diameter required for your wheels.
• Ensure proper alignment during installation to maintain wheel balance and avoid uneven wear.
• Follow the provided non-braked hub assembly instructions to ensure correct seating and retention of the hub on the axle tube.
• Regularly inspect the welds and hub flange for signs of stress or wear, especially in trailers that operate under heavy loads or rough terrain.
• Keep a ready set of spare parts on hand—supplied options cover common wear items and components to minimize downtime.

Who benefits most

Ideal for trailer builders, agricultural and light-industrial equipment, and enthusiasts retrofitting old axles with a robust, weld-in hub solution. It’s especially suitable for users who prioritise strong, permanent hub connections and broad compatibility with common wheel patterns without incorporating braking hardware into the hub assembly.

How it compares to alternatives

Compared with braked hub options, this non-braked kit prioritises a straightforward, weld-in installation and a simple hub-to-axle interface. If your application requires integrated braking, you’ll want a braked hub kit—but for heavy-load, off-road, or retrofitting scenarios where a clean, welded hub is preferred, this 160HUB series kit delivers.

In summary, the Hub and Stub Kits 4x4 1/4/x7/16 160HUB offer a durable, versatile, weld-in solution with broad stud-pattern support, a strong 1500 kg GVM rating, and the practical details you need for reliable, long-term operation in demanding environments.
