Hub and Stub Kits 1500kg Disc/B 120mmx7/16

Meet the Hub and Stub Kits 1500kg Disc/B 120mmx7/16 — a durable, braked hub solution built for reliable trailer performance. Designed to fit Trojan Duratorque and beam axles, this kit is also compatible with most NZ-manufactured trailer axles, making it a versatile choice for a wide range of setups.

Why this kit stands out

• Solid 1500kg GVM per axle — engineered around a pair of hubs to handle the demanding loads of single-axle trailers with confidence.
• Flexible disc mounting — choose between a full cast disc or a bolt-on disc, available in cast iron or stainless steel, to match your braking needs and corrosion resistance requirements.
• Ready-to-fit stub axles — includes a pair of 38mm round stub axles with a built-in caliper mount for straightforward installation.
• Brake calipers sold separately — you retain control over your braking kit configuration while keeping the core hub assembly lean and adaptable.
• Broad stud-pattern compatibility — a wide range of wheel stud patterns ensures you can match most common rims and tyres in the market, with 5-stud and 4-stud configurations covered.

Compatibility and configurations

The hubs are designed for Trojan Duratorque and beam axles, and they should fit most NZ-manufactured trailer axles as well. The available configurations cover both integral (disc already mounted on the hub) and bolt-on disc options, giving you the right balance between ease of maintenance and upgrade flexibility.
