Upgrade your trailer’s braking with Hub and Stub Kits SS Disc 5x4 1/2x1/2 — a purpose-built solution designed to deliver reliable stopping power on Trojan Duratorque and beam axles, while remaining compatible with a wide range of NZ-made trailer axles. Each kit is engineered to support a single axle with a 1500kg GVM rating per pair of hubs, giving you confident performance for everyday hauling.

Why these hub kits stand out

• While optimized for Duratorque and beam axles, these hubs are designed to fit most NZ trailer axles, making them a versatile choice for builders and retrofits alike.
• The most common wheel setup for NZ trailers is supported, with the 5 Stud configuration and a 4 1/2" PCD to suit a wide range of rims and tyres. This means fewer compatibility headaches and simpler wheel choices.
• Each kit ships with a pair of stub axles that feature a built-in caliper mount, streamlining installation and alignment for reliable braking performance.
• Choose between a full cast disc (integral) or a fitted bolt-on disc offered in both cast iron and stainless steel. Stainless options provide enhanced durability in challenging environments, including coastal applications.
• The brake calipers are not included in the kit, allowing you to select the caliper style that best matches your preferred braking power and maintenance plan.
• Packaged for shipment from suppliers with an estimated dispatch window of 4–7 days, helping you plan ahead for your trailer project.
• A compact, manageable kit that’s straightforward to handle during installation and service.

What you get and how it works

These braked hub kits come in a range of configurations to suit different wheel and rotor setups, all built around a 5x4 1/2" stud pattern and a 1/2" stud width variant in certain options. The range includes:

• Integral (disc) options with a full cast disc, designed for straightforward maintenance and robust performance.
• Bolt-on disc variants available in cast iron or stainless steel, offering flexibility for long-term corrosion resistance and refits.

Who this is for and ideal use cases

• Trailer builders and restorers looking for a reliable, easy-to-fit braking hub solution that aligns with common NZ trailer practices.
• Owners upgrading braking on caravans, boat trailers, or light-to-medium duty equipment trailers that rely on the 5x4 1/2" wheel pattern.
• Custom trailer projects where Duratorque or beam axles are in use, but compatibility with other NZ-made axles is beneficial.

Practical considerations and tips

• Choose stainless steel bolt-on discs when coastal or high-salinity environments are a factor to improve corrosion resistance and longevity.
• Plan for caliper selection separately to match your preferred braking performance and maintenance schedule.
• Review your current axle type (Duratorque or beam) to confirm compatibility with the hub pattern and stub axle configuration.
• When sizing for replacement, note the 1500kg GVM rating per axle as a guidance for typical loads; always ensure your entire trailer configuration complies with local regulations and safe operation practices.

Why this kit might be the right upgrade over alternatives

• Designed for common NZ axle configurations while still offering broad compatibility, reducing the complexity of choosing the wrong hub for your trailer.
• Combination of integral and bolt-on disc options provides a balance between maintenance simplicity, cost, and corrosion resistance depending on your environment and usage.
• Inclusion of 38mm stub axles with a caliper mount streamlines installation and alignment, supporting consistent braking performance from day one.
