Hub/Stub Kit 1750kg Integral Disc 5x120x7/16

Discover reliable braking power and versatile fit with the Hub/Stub Kit 1750kg Integral Disc 5x120x7/16. Built to align with Trojan products while delivering broad compatibility for NZ trailer axles, this kit is designed for builders who demand strength, straightforward installation, and long-term durability on the open road.

Why this hub and stub kit stands out

• High load capability — a 1750kg GVM rating per axle (based on a pair of hubs) provides confident performance for a wide range of trailers, from boats to caravans and light-commercial setups.
• Flexible disc options — choose between a full cast disc or a bolt-on disc assembly in either cast iron or stainless steel, giving you corrosion resistance where it matters and compatibility with your preferred rim configuration.
• Wide compatibility — designed to fit Duratorque and beam axles, with strong compatibility for most NZ manufactured trailer axles, plus the common 5-stud pattern (PCD 4 1/2 inches) that matches many stocked rims and tires.
• Precise stud patterns — available in multiple configurations to suit your wheel selection, including 5x120mm patterns and 7/16" stud widths for secure mounting.
• Integrated stub design — comes with a pair of 38mm round stub axles featuring a built-in caliper mount, simplifying alignment and mounting for brake systems (calipers sold separately).
• Plug-and-play practicality — optimized to fit Trojan lines while remaining adaptable enough to support NZ-built axles, making replacement and upgrades straightforward.
• Complete and ready-to-ship — order includes rugged components in a compact 20kg pack, with spare parts available and shipments dispatched within 4–7 days.

Who it's for and how it helps

This hub/stub kit is ideal for trailer builders and do-it-yourself refurb projects on NZ trailers, especially when you’re updating or upgrading braking performance on Duratorque or beam axles. If you’re replacing worn hubs or upgrading to an integral disc system, this kit delivers a robust, corrosion-conscious option (with stainless bolt-on discs available) and a clear path to reliable braking across a variety of wheel configurations.

Practical tips and considerations

• When selecting a disc style, consider environmental exposure: stainless steel bolts or discs provide enhanced corrosion resistance for saltwater or trailer parks near coastlines.
• Check your wheel stud pattern before ordering—this kit is optimized for the 5x pattern with 4 1/2" PCD but offers alternatives in the same family to match your rims.
• Calipers are sold separately, so plan for compatible calipers that fit your chosen disc type to complete the braking system.
• Parts are available separately, so ongoing maintenance or future upgrades are straightforward without replacing the entire kit.

With the Hub/Stub Kit 1750kg Integral Disc 5x120x7/16, you get a purpose-built, durable braking hub solution that emphasizes compatibility, ease of installation, and long-term reliability for NZ trailer applications.
