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

Hub Kit 6X51/2X1/2 CI Disc Braked 2000kg is engineered to elevate trailer braking performance with a robust 275 mm disc rotor integrated into each hub. Designed for reliability on NZ-made trailer axles and readily compatible with Duratorque and beam axles, this disc-braked hub kit covers a wide range of common wheel stud patterns for versatile rim compatibility.

• Disc Braked design with a 275 mm rotor: The rotor is either an integral cast iron unit or a bolt-on rotor (cast iron or stainless steel), paired with our standard caliper sets (sold separately) for strong, progressive stopping power on longer tows.
• High-capacity 2000 kg GVM (per axle, pair of hubs): Built to support demanding loads while maintaining smooth braking performance across a wide range of trailer applications.
• Wide stud pattern support: Our hubs cover a variety of wheel stud configurations, with the most common 6×5½" (PCD ≈ 67.183 mm) pattern aligned with commonly stocked rims and tyres.
• Comprehensive hub dimensions (Current vs Early models):
  • Current Model: Outer Bore 45 mm, Inner Bore 65 mm, Flange Thickness 15 mm, Flange Diameter 220 mm, Boss Length 30 mm, Rotor Diameter 275 mm.
  • Early Model: Outer Bore 50 mm, Inner Bore 65 mm, Flange Thickness 15 mm, Flange Diameter 220 mm, Boss Length 30 mm, Rotor Diameter 275 mm.
  • Spigot Type (Current Model): Outer Bore 50 mm, Inner Bore 65 mm, Flange Thickness 13 mm, Flange Diameter 190 mm, Boss Length 30 mm, Rotor Diameter 275 mm or 260 mm.
• Part details and compatibility: Part No: T038155; 6 studs; PCD 5½" (≈ 67.183 mm); Stud Width 1/2" (12.7 mm); overall diameter around 67.183 mm. Pack weight ≈ 21 kg.
• Practical availability: Spare parts range available; products ship from the supplier within 4–7 days.

Who this is for: trailer owners and operators using Duratorque or beam axles, and anyone seeking a durable disc-braked upgrade compatible with NZ-manufactured trailer axles. The kit’s broad compatibility with common wheel sizes and its robust 2000 kg per-axle rating make it a practical upgrade for utility trailers, caravans, boat trailers, and light commercial setups.

How it helps you solve problems: upgrading to a disc-braked hub kit improves heat dissipation and braking consistency on longer or heavier tows, reduces fade on repeated stops, and provides a reliable, maintainable braking solution when paired with the appropriate caliper sets (sold separately). The option for either an integral rotor or a bolt-on rotor in cast iron or stainless steel offers flexibility to match your preferred service life and corrosion resistance.

Installation and use tips: verify bore sizes and flange dimensions to ensure a perfect fit with your axle, select the correct rotor configuration (integral vs bolt-on), and pair with compatible caliper kits. Keep spare parts on hand for quick maintenance, and note the 4–7 day dispatch window when planning replacements or upgrades.
