Hub Kit 5X41/2X2 S/S Disc Braked 2000kg

Meet the Hub Kit 5X41/2X2 S/S Disc Braked 2000kg—built to elevate the braking performance and reliability of heavy trailers. With a 2000kg GVM rating per axle, this disc-braked hub kit delivers confident stopping power for demanding loads, while offering flexible rotor configurations to suit your setup. This isn’t a generic upgrade—it's a purpose-built solution for Duratorque and beam axles, and it’s compatible with a wide range of NZ-manufactured trailer axles.

Why this hub kit stands out

• Heavy-duty performance: 2000kg GVM rating per single axle (pair of hubs) ensures dependable handling when towing large payloads.
• Flexible rotor integration: rotors are either an integral part of the cast-iron hub or fitted as a bolt-on disc rotor available in cast iron or stainless steel, with a robust 275mm rotor diameter for strong braking leverage.
• Common, versatile stud pattern: designed around the popular 5 studs with a 4 1/2 inch PCD, aligning with the majority of stocked rims and tyres for straightforward compatibility.
• Disc braking with standard calipers: the hub kit includes a disc rotor option and uses standard caliper sets (sold separately), giving you flexibility in choosing your braking components.
• Multiple model configurations: available in current and early models with distinct outer bore, inner bore, flange, and rotor options to suit a range of installations. There’s also a spigot-type variant to match different hub mounting requirements.
• Broad axle compatibility: specifically engineered to fit our Duratorque and beam axles and is widely compatible with most NZ-manufactured trailer axles.
