Meet the Hub Kit 5X41/4X7/6 SS Disc Braked 1500kg — a rugged, stainless steel disc-braked hub system built to take on heavy trailers with confidence. Designed to fit Duratorque and beam axles and broadly compatible with NZ-made trailer axles, this kit delivers reliable stopping power and lasting performance under demanding loads. With a 1500 kg GVM rating per axle (based on a pair of hubs), it’s engineered for serious work without compromise.

• Disc-braked reliability: A true disc braking solution that provides consistent braking response in varied conditions, reducing fade on longer pulls and improving overall trailer control.
• Wide compatibility: Available in multiple wheel stud patterns to suit the most common rims, including 4-stud and 5-stud configurations. The most common option is 5-stud with a 4.5" PCD (114.3 mm), with additional patterns featuring 4.25" (108 mm) and 4.5" (114.3 mm) PCD, plus a 120 mm pattern for select fits.
• Material and disc options: Choose between a full cast disc or a bolt-on disc, with rotor options in cast iron or stainless steel to match your trailer’s operating environment and maintenance preferences. Rotor sets available: TPT3110 (Cast Iron) or TPT3111 (Stainless Steel), each packed for dependable performance.
• Versatile rotor diameter: Standard rotor diameter is 225 mm, with current spigot-type models offering 225 mm or 260 mm to optimize braking bite for different axle configurations.
• Integral and bolt-on configurations: The hub kits cover a range of bore and flange specifications (outer bore, inner bore, flange thickness, and flange diameter) to fit both Duratorque and beam axles, while remaining compatible with a broad array of NZ-manufactured trailer axles.
• Simple sizing and parts support: Rotor and hub combinations are available in several bore sizes and stud patterns, so you can select exactly the pattern that matches your rims and tyres. Spare parts and rotor sets are available to keep downtime to a minimum.

What’s included and how it helps you

• New hub kit with disc-braked capability designed for 1500 kg GVM per axle — ideal for trailers in industrial, livestock, or multi-purpose use where reliability matters as much as payload.
• Rotor sets available in both cast iron and stainless steel options to suit corrosion resistance needs and service life expectations.
• Full cast disc or bolt-on disc configurations let you tailor the setup to your existing wheels and mounting tolerances.

Common use cases

• Mid-to-heavy duty trailer applications requiring robust braking performance on Duratorque or beam axles.
• NZ-built or imported trailers where multiple stud patterns are needed to match a wide range of rims and tyres.
• Maintenance-friendly setups where spare rotor options (cast iron or stainless) simplify field repairs or upgrades.

Why this hub kit stands out

• Duratorque and beam-axle compatibility combined with a broad range of stud patterns makes this a flexible, future-proof choice for trailer fleets and DIY enthusiasts alike.
• Stainless steel rotor options deliver enhanced corrosion resistance for trailers exposed to harsh environments, salt air, or frequent washdowns.
• Clear build data and bore/ flange specs help you pinpoint the exact assembly you need, reducing guesswork during installation.

Practical notes

• Rotor sets and spare parts are available, with shipments typically dispatched within 4–7 days from order.
• The kit weight and dimensions align with standard trailer maintenance workflows, making swap and upgrade straightforward for qualified technicians.
• The 1500 kg GVM rating covers a single axle with two hubs, ensuring predictable load handling when paired correctly on your trailer.

Whether you’re upgrading an older trailer or equipping a new build, the Hub Kit 5X41/4X7/6 SS Disc Braked 1500kg delivers dependable braking performance, flexible mounting options, and the durability you expect from a purpose-built disc-braked hub system.
