Hub and Stub Kit 2000kg D/B 5x4 1/2x1/2

Upgrade your trailer with the Hub and Stub Kit 2000kg D/B 5x4 1/2x1/2 — a versatile, non-braked hub solution designed to fit Trojan components and most NZ trailer axles. Built to a 2000kg GVM rating per single axle (based on a paired hub setup), this kit provides a robust foundation for reliable load handling and flexible brake configuration options.

Why this hub kit stands out

• Broad compatibility: engineered to fit Duratorque and beam axles, with strong confidence it will suit most NZ-manufactured trailer axles and Trojan systems.
• High-capacity performance: 2000 kg GVM per axle (as a pair of hubs) delivers capable payload handling for common trailer applications.
• Flexible wheel compatibility: supports common stud patterns, including 5-stud 4.5" PCD and 6-stud 5.5" PCD, plus 5-stud 120mm variants for specific rims.
• 275mm rotor diameter: designed to work with standard caliper sets (sold separately), with rotor options integrated into the hub or available as bolt-on rotors in cast iron or stainless steel.
• Built-in mounting for future braking: each kit includes a pair of 38mm round stub axles with a built-in caliper mount, simplifying a potential brake upgrade later.
• Non-braked by design: ideal as a versatile foundation that can be upgraded to disc braking without swapping the entire hub assembly.

Rotor and stud configurations you can choose from

The hub kits offer multiple rotor configurations to suit your preferred material and budget, all with a 275mm rotor diameter and standard caliper compatibility (caliper sets sold separately).

What you get, and practical usage notes

This hub and stub kit ships as a complete package designed for straightforward installation on compatible trailers. Each kit includes a pair of 38mm round stub axles with an integrated caliper mount, ready for a future brake upgrade or immediate use in non-braked configurations. The product is designed to fit Trojan components but should accommodate most NZ trailer axles, making it a flexible choice for mixed fleets or upgrades.

Key practical benefits you’ll notice in the field:

• Streamlined maintenance with clearly defined part options for rotors and calipers, reducing downtime when matching or upgrading components.
• Flexibility to migrate from non-braked to disc braking by selecting compatible bolt-on or integral rotor configurations.
• Wide wheel compatibility thanks to multiple stud patterns, enabling reuse of existing rims while upgrading the hub assembly.
