Hub and Stub Kits 225 SS Disc 5x120x7/16

Upgrade your trailer braking with Hub and Stub Kits 225 SS Disc 5x120x7/16, precisely engineered to fit Trojan Duratorque and beam axles while offering broad compatibility with NZ‑made trailer systems. This kit is built to handle demanding loads, deliver reliable stopping power, and simplify maintenance for both professional fleets and weekend DIYers.

Why this kit stands out

• : Each hub pair is rated with a 1500 KG GVM (Gross Vehicle Mass) per single axle, giving you confident braking performance even under heavy loads and long hauls.
• Versatile braking disc options: Choose between a full cast disc or a bolt‑on disc, available in cast iron or stainless steel. This lets you tailor corrosion resistance, heat management, and service life to your environment and budget.
• Solid stub axle integration: Includes a pair of 38mm round stub axles with a built‑in caliper mount, streamlining installation and alignment for consistent braking performance.
• Wide wheel compatibility: Designed to fit our Duratorque and beam axles, and broadly compatible with most NZ manufactured trailer axles. The range covers multiple wheel stud patterns to suit the most common rims and tyres, including the 5‑stud configuration on a 120mm bolt circle with 7/16" wheel studs.
• Calipers sold separately: The kit focuses on delivering strong hub and rotor performance, while allowing you to source compatible calipers to match your preferred braking setup.
• Spare parts availability: A broad range of spare parts supports easy maintenance and long‑term reliability, so you can keep your brakes performing at peak efficiency.
• Practical packaging and lead time: Each package is designed for straightforward installation and ships within 4–7 days, with a pack weight of around 20 kg for efficient handling and logistics.

What you get and how it works

The Hub and Stub Kits 225 SS Disc combine a durable hub assembly with a choice of disc configurations to suit your preferred balance of strength, corrosion resistance, and ease of maintenance. You’ll be choosing between Integral (disc built into the hub) and Cast Iron bolt‑on disc options, with stud widths of 7/16" or 1/2" and compatible patterns around 4 1/4" to 5 stud configurations. This flexibility makes it easier to match your existing rims and drum replacements without compromising braking efficiency.

Ideal use cases

• Replacing worn or corroded hubs on trailers using Duratorque or beam axles, especially where NZ specifications are common.
• Upgrading from drum brakes to a disc setup for improved heat dissipation and consistent stopping power on longer or heavier hauls.
• Parts‑oriented rebuilds where you want the option of stainless steel components to resist coastal or humid environments.
• Fleet upgrades where standardization on a common hub kit reduces inventory and simplifies maintenance scheduling.

How this compares to alternatives (without naming brands)

Compared to single‑purpose drum hubs, these disc hub kits offer better heat management under heavy braking, reducing the risk of fade on steep descents. The option to choose between integral and bolt‑on discs means you can optimize for installation simplicity or maximum serviceability in harsh environments. Stainless steel versions provide superior corrosion resistance for coastal regions, while cast iron versions can offer cost savings for non‑marine applications. With a built‑in caliper mount and ready‑to‑install stub axles, the system minimizes misalignment risks and simplifies field servicing.

Helpful tips for selecting the right kit

• Confirm your wheel stud pattern and stud width (commonly 7/16" or 1/2") and whether you need a fixed integral disc or a bolt‑on rotor configuration.
• Match the bolt circle pattern to your rims for a secure, true fit. The 5‑stud 120mm pattern is a key option in this range.
• Decide on material based on environment: stainless steel for coastal or salty atmospheres; cast iron when budget is a priority and braking demands are moderate.
• Plan caliper compatibility in advance since calipers are sold separately—ensure the chosen disc type aligns with your preferred caliper model.

Bottom line: Hub and Stub Kits 225 SS Disc 5x120x7/16 offer a ready‑to‑install, durable braking upgrade for NZ trailers that balances rugged performance with flexible configuration options. Whether you’re replacing aging hubs, upgrading to better heat management, or standardizing a fleet, this kit provides the efficiency, compatibility, and long‑term reliability you need on the road.
