Trojan Hub Kit 5x41x4x7x16 Disc Braked 1500kg For Duratorque NZ Trailer Axles Heavy Duty Trailer Braking

Upgrade your trailer’s braking performance with the Hub Kit 5x41/4x7/16 Disc Braked 1500kg. Engineered for durability and reliability, this disc-braked hub kit is designed to fit Duratorque and beam axles while remaining compatible with a wide range of NZ-manufactured trailer axles. With a 1500 kg GVM rating per axle (based on a pair of hubs), it’s built to handle demanding loads with confidence.

Why this hub kit stands out

• : Compared to traditional drum systems, disc brakes provide stronger bite, better heat dissipation, and reduced fade on long pulls or heavy-tow scenarios—ideal for caravan, forestry, and work trailers.
• : While optimized for Duratorque and beam axles, these hubs suit most NZ-manufactured trailer axles and a wide variety of wheel stud patterns, with the most common 5-stud pattern (PCD around 4.5 inches) fitting the majority of stocked rims and tyres.
• : Choose between a full cast disc or a bolt-on disc in either cast iron or stainless steel, letting you tailor durability and corrosion resistance to your environment.
• : The standard current model features a 45mm outer bore, 59mm inner bore, 180mm flange diameter, and a 225mm rotor diameter (with a boss length of 34mm). Early models share the same outer/inner bores and flange diameter, but with a 27mm boss length. For spigot-type setups, inner bore is 12mm, rotor diameter can be 225mm or 260mm, depending on the configuration.
• : Rotor options are supported by dedicated sets—TPT3110 (Cast Iron) and TPT3111 (Stainless Steel)—available as part of a practical 15 kg rotor kit. This makes replacements and upgrades straightforward without buying a full assembly.
• : The range covers integral hubs in 5 patterns, including 4 1/4" and 4 1/2" PCD with 7/16" or 1/2" studs, and 120mm variations, ensuring you can match your existing rims precisely.

What’s included and how it’s used

Each hub kit is designed for a 1500 kg GVM per axle (two hubs), giving you a dependable braking solution for trailers that regularly haul substantial loads. The kits are offered in standard, bolt-on, and spigot-type configurations to cover the most common mounting setups, with rotor sets available separately (TPT3110 Cast Iron or TPT3111 Stainless Steel) for easy customization or replacement.

Ideal for

• Trailers that demand stronger, cooler braking under load—caravans, builder’s trailers, and heavy-duty equipment trailers.
• Installations on Duratorque and beam axles, with broad compatibility for NZ-manufactured trailer axles.
• Users upgrading from drum brakes who want improved stopping power and corrosion resistance, especially in harsh or salty environments (stainless disc options available).

Practical considerations and setup tips

• Carefully verify your wheel stud pattern and bore type before purchasing to ensure a perfect match with your rims and hubs.
• For coastal or salted environments, consider the stainless steel bolt-on disc option for enhanced corrosion resistance and longevity.
• Rotor sets (TPT3110 Cast Iron or TPT3111 Stainless) are a cost-effective way to refresh braking performance without reworking the entire hub kit.
• Parts availability and shipping: the product and spare components are sourced from suppliers and typically ship within 4–7 days; rotor set options come as part numbers TPT3110 or TPT3111, with a 15 kg package weight for the rotor kit.

Designed to deliver dependable stopping power when it matters most, the Hub Kit 5x41/4x7/16 Disc Braked 1500kg is a practical, versatile upgrade for trailers that work as hard as you do.
