Hub Kit 6X51/2X1/2 SS Disc Braked 2000kg

The Hub Kit 6x5 1/2in 1/2in SS Disc Braked 2000kg is built for trailer longevity and precise stopping power. Designed to fit Duratorque and beam axles—and widely compatible with NZ-manufactured trailer axles—this disc-braked hub kit delivers dependable performance under demanding loads.

Key benefits that set this kit apart:

• Strong, predictable load capacity — 2000 kg GVM per axle when used as a paired hub set, giving you clear headroom for heavy loads and confident road handling.
• 275 mm disc rotor with flexible mounting — rotor diameter of 275 mm provides robust braking bite. The hub kit can include an integral cast-iron rotor or a bolt-on rotor in either cast iron or stainless steel, with calipers sold separately to let you tailor the braking system to your needs.
• Multiple hub configurations for versatile builds — three common configurations to suit different trailer architectures:
  • Current Model: Outer Bore 45 mm, Inner Bore 65 mm, Flange Thickness 15 mm, Flange Diameter 220 mm, Boss Length 30 mm.
  • Early Model: Outer Bore 50 mm, Inner Bore 65 mm, Flange Thickness 15 mm, Flange Diameter 220 mm, Boss Length 30 mm.
  • Spigot Type: Outer Bore 50 mm, Inner Bore 65 mm, Flange Thickness 13 mm, Flange Diameter 190 mm (or 260 mm in some setups), Boss Length 30 mm.
• Wide compatibility with stud patterns — while the most common stud pattern is 5 studs with a 4 1/2 in PCD, this hub range covers a broad variety of wheel stud configurations to fit the rims you already rely on.
• Durable construction and materials — stainless steel variants offer enhanced corrosion resistance for coastal or salted-road use, while cast-iron rotors keep maintenance cost low for everyday work.
• Practical installation notes — the rotor is an integral part of the hub in some versions or bolt-on in others, so you can choose the setup that best matches your axle type and brake caliper choices. Caliper sets are sold separately, giving you flexibility to source precisely what you need.

Who benefits most from this hub kit? trailer builders, fleet operators, and weekend warriors who demand reliable braking under heavy loads. If you’re upgrading an older trailer or assembling a new one on NZ-made axles, this kit’s 2000 kg GVM rating per axle and 275 mm rotor diameter provide a solid, long-term braking foundation.
