Trojan Hub Kit 5x4.5 Bolt On Rotor 1500kg for Trailers

The Hub Kit 5x41/2x1/2 Bolt on Rotor 1500kg is a robust, non-braked hub solution designed to simplify trailer upgrades now and into the future. Engineered to fit Trojan’s Duratorque and beam axles, it’s also compatible with a wide range of NZ‑manufactured trailer axles, making it a practical choice for commercial trailers, caravans, and heavy‑duty towing setups.

• Heavy‑duty GVM: rated for 1500 kg per axle (based on a pair of hubs), giving you confidence when transporting demanding loads.
• Non‑braked by design, brake‑ready: ships as a bolt‑on hub kit without a disc, but is fully upgradeable to a braked system later with compatible rotor and caliper components (see upgrade options below).
• 5‑stud pattern with common wheels: the well‑established 5‑stud drill pattern and 4.5 inch PCD are chosen for compatibility with the majority of stocked rims and tyres.
• Bike‑shop precision dimensions: hub dimensions correspond to a reliable, repeatable fit — outer bore 45 mm, inner bore 59 mm, flange thickness 11 mm, flange diameter 155 mm, overall width 97 mm (spigot type noted on the current model).
• Wheel compatibility and fitment: designed to fit Trojan’s Duratorque and beam axles and is widely compatible with NZ‑made trailer axles, ensuring straightforward retrofits without custom machining.
• Discs not included, but upgradeable: the kit is supplied without a disc, but you can upgrade to a disc rotor kit (TPT3110 cast iron or TPT3111 stainless) and caliper kit (TPT1098 cast iron or TPT1298 stainless) when you’re ready to add braking power.
• Easy forward planning: the non‑braked hub kit is deliberately designed to accept a later braking upgrade, so you won’t be locked into a single configuration.
• Complete, ready‑to‑fit package: each hub kit weighs around 7 kg and is designed for straightforward bolt‑on installation. Stub axles are not included, and the kit is supplied with the necessary hardware for quick mounting.
• Spare parts and support: dedicated spare parts are available (T610140, T610135, T610125) to help keep maintenance simple and downtime minimal.
• Delivery and lead time: products are shipped from suppliers with typical dispatch in 4–7 days, so you can plan upgrades with clarity.

Ideal use cases: trailers that routinely carry heavy loads or require a future braking upgrade without re‑machining hubs, such as equipment trailers, heavy‑duty utility trailers, boat trailers, and fleet applications. It’s especially suitable for owners and mechanics who want a simple, dependable bolt‑on hub that can evolve into a full brake system as needs change.

Why this matters: choosing this hub kit means you get a proven, common 5‑stud pattern hub with a solid 1500 kg per axle rating, designed for real‑world trailer use. The ability to upgrade brakes later protects your initial investment while giving you the flexibility to enhance stopping power when the job demands it. It’s a pragmatic, future‑proof solution that stays compatible with your existing wheels and axles.
