Hub and Stub Kits 5x4 1/4x7/16 160HUB 39mm S/A

Hub and Stub Kits 5x4 1/4x7/16 160HUB 39mm S/A are purpose-built, non-braked hub kits designed for straightforward, reliable trailer axles. Featuring a weld-on 38mm diameter stub axle, these hubs are engineered to join seamlessly with your axle tube for a strong, simple mounting solution.

The heart of this kit is durability paired with practical versatility. With a GVM rating of 1500kg per single axle (based on a pair of hubs), they strike a balance between heavy-duty capability and manageable weight. This makes them ideal for a wide range of trailers, from utility and work trailers to small caravans and boat haulers that don’t require integrated braking systems.

Why this hub kit stands out

• Weld-on stub axle: A robust 38mm diameter stub axle designed to be welded directly to your axle tube, delivering a solid, permanent mounting point with minimal assembly steps.
• Broad compatibility with wheel patterns: A wide range of stud patterns accommodates common wheel configurations, with the most frequently used option being a 5-stud pattern and a 4-1/2" PCD. This helps you pair the kit with a broad selection of rims and tyres you’re likely to already own or source easily.
• Standard flange diameter: 160mm flange diameter provides a generous face for load distribution and compatibility with many popular rims.
• Stud width versatility: Typical 7/16" stud width across many variants, with some configurations offering 1/2" studs for heavier rims and hardware.
• Not compatible with bolt-on disc rotors: This kit is designed for non-braked applications; if you need braking, plan for a drum-brake or alternative setup separately.
• Clear part availability and fast shipping: A range of spare parts is available, and products are shipped from the supplier within 4–7 days, helping you keep your project on schedule.
• Solid weight and packing: Pack size around 9kg, making handling and installation straightforward for most workshop setups.

Ideal use cases

• DIY trailer builds where a reliable, weld-on hub is preferred for a clean, uncluttered axle design.
• Boat trailers, utility trailers, and light-to-medium duty caravans that require a straightforward, non-braked hub system.
• Projects that prioritize ease of installation and compatibility with a wide range of common rims and tyres.

Compatibility and configurations

This hub kit line features multiple wheel stud patterns to suit common rim sizes and configurations.
