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

Meet the Hub Kit 6X51/2X1/2 Disc Braked 2000kg — a purpose-built hub solution designed for demanding trailer work. This disc-braked hub kit delivers sturdy performance onDuratorque and beam axles while remaining compatible with a wide range of NZ-manufactured trailer axles. With a 2000kg GVM rating per axle (based on a single axle and a pair of hubs), it’s engineered to handle serious loads on utility, flatbed, or equipment trailers.

Why chooseDisc Braked hubs? The integrated disc rotor design enhances braking efficiency, heat dissipation, and fade resistance in demanding conditions. You can select either an integral cast iron rotor or a bolt-on rotor option in cast iron or stainless steel, giving you flexibility for performance, durability, and corrosion resistance in harsh environments. The standard rotor diameter is 275mm, and you’ll pair these hubs with your preferred caliper set (sold separately) to complete the braking system.

Key compatibility and use cases

• Stud pattern and fit: 6 studs with a 5 1/2 inch (139.7mm) PCD and 1/2 inch stud width. This setup matches common trailer rims and provides broad compatibility for many wheel configurations.
• Axle compatibility: Specifically designed for Duratorque and beam axles, with broad applicability to NZ-manufactured trailer axles. If you’re upgrading braking performance on a trailer built for tough jobs, this hub kit is a proven choice.
• Braking configuration: Disc-braked hub with a 275mm rotor. You’ll benefit from steadier braking force and improved heat management in heavy-duty or frequent-stop scenarios, such as construction sites, forestry work, or long-haul towing in hilly terrain.
• Spare parts availability: A range of spare parts is available to keep your trailer in service, with sensible support for maintenance and replacements over time.

Variant options and dimensional overview

Our hub kits come in several version variants to match different axle designs and mounting requirements. Referencing the specified measurements, you can verify compatibility with your existing setup:

• Outer Bore 45mm, Inner Bore 65mm, Flange Thickness 15mm, Flange Diameter 220mm, Boss Length 30mm, Rotor Diameter 275mm.
• Outer Bore 50mm, Inner Bore 65mm, Flange Thickness 15mm, Flange Diameter 220mm, Boss Length 30mm, Rotor Diameter 275mm.
• Outer Bore 50mm, Inner Bore 65mm, Flange Thickness 13mm, Flange Diameter 190mm, Boss Length 30mm, Rotor Diameter 275mm or 260mm.

These details reflect the range’s versatility — whether you’re maintaining an older build, upgrading to a modern disc-braked setup, or working with a spigot-type hub arrangement, you’ll find a compatible configuration within this hub family.

What this means for you

• Improved braking performance: Disc brakes offer more predictable stopping power under load and during prolonged use, reducing heat buildup compared with drum-only configurations.
• Durability and adaptability: The hub design accommodates both integral and bolt-on rotor options, with material choices (cast iron or stainless steel) to suit different climates and corrosion exposure.
• Practical for builders and fleets: Ideal for trailer builders, maintenance teams, and fleet operators who demand a robust, easily sourced hub kit with broad axle compatibility and straightforward replacement parts.

Who benefits most

This hub kit is a strong fit for professionals and enthusiasts building or upgrading heavy trailers that require dependable braking, such as construction equipment trailers, agricultural transports, utility and service trailers, or heavy-duty flatbeds. If you’re working with Duratorque or beam axles and need a proven 2000kg GVM solution, this disc-braked hub kit is designed to deliver.

Practical tips and considerations

• Before purchasing, verify your axle type (Duratorque or beam) and confirm the appropriate bore and flange dimensions match your existing hub assembly or rotor configuration.
• Plan for caliper availability — the disc rotor is standard at 275mm, and calipers are sold separately. Ensure your chosen caliper is compatible with the rotor diameter and mounting standards of your trailer system.
• Check for spare parts alignment with your hub version (standard, early, or spigot type) to ensure you select the correct outer bore, inner bore, and flange dimensions.
• For longevity in challenging environments, consider a stainless steel rotor option if corrosion resistance is a priority and your operating conditions expose components to moisture or salt.

Delivery and availability: This hub kit is typically dispatched from stock with reliable supplier logistics, offering a practical, ready-to-install solution for immediate upgrades or new builds. If you’re updating a trailer’s braking system to improve safety, control, and performance, the Hub Kit 6X51/2X1/2 Disc Braked 2000kg provides a well-supported, widely compatible path to stronger stopping power on heavy-duty trailers.
