Engineered for professional wheel builders, restorers, and fabrication shops, the Trojan Hub Blank 225mm is a precise starting point for custom wheels and authentic restorations. This 225mm blank hub is specifically configured for the 4x110 bolt pattern, making it an ideal foundation when accuracy and adaptability matter most.

Why a hub blank matters

Unlike pre-drilled or feature-laden hubs, a blank hub gives you unbounded control over the final assembly. It’s the clean slate you need to tailor rotor interface, disc or drum configurations, center bore decisions, and stud alignment to your exact project requirements. For restoration work, this means you can reproduce original specifications or implement a modern, performance-focused setup without unnecessary constraints.

Key specifications and what they mean for you

• Diameter: 225mm — a substantial, stable base designed to work with a wide range of wheel centers and interfaces.
• Bolt pattern: 4x110 — a common configuration for trailers, go-karts, and select classic vehicles, enabling a broad spectrum of wheel options.
• Type: Blank hub — no disc face or integrated brake interface installed, maximizing customization opportunities.
• Part/mold reference: ONT600105 (2008-on catalog variant) — traceable model designation for compatibility checks and ordering within Trojan’s line.
• Discipline-ready design: Suitable for both disc-free and disc-braked setups, depending on how you machine the hub and what brake system you plan to integrate.

Who this is built for

This hub blank is particularly well-suited for:

• Professional wheel builders fabricating bespoke wheels or restoring period-correct assemblies.
• Go-kart and small-vehicle projects requiring a precise 4x110 hub base.
• Restoration shops aiming to reproduce authentic hardware while retaining maximum future customization options.
• Fabrication shops that need a reliable, repeatable foundation for custom wheel centers and mounting assemblies.

Practical use cases and outcomes

• Restore a vintage setup that originally used a 4x110 bolt circle by starting from a true blank hub and machining your own disc interface and stud layout.
• Set up a go-kart or light trailer project with a robust 225mm hub diameter, then tailor the brake interface to your preferred system.
• Develop a custom wheel program in-house, using the blank hub as a repeatable starting point to accelerate fabrication timelines.

How it compares to alternatives

Choosing a hub blank like this Trojan unit offers distinct advantages over pre-drilled or disk-ready hubs. You’re not restricted by existing disc face geometry or drum-fit constraints, which means fewer compromises when matching a particular wheel center, rotor size, or brake configuration. If you’re building or restoring wheels with a 4x110 bolt pattern, a blank hub minimizes the need for adapters or spacers and supports clean, concentric mounting with your chosen wheel center.

Installation and handling tips

• Verify the 4x110 bolt pattern before machining or bolting a wheel to ensure proper alignment and load distribution.
• When converting a blank hub to a disc-braked or drum-braked configuration, use precise templates and maintain concentricity to preserve wheel balance and safety.
• Plan your brake interface early in the process—the blank nature of this hub makes it an ideal candidate for a custom, purpose-built rotor or drum arrangement.
• Inspect the hub bore area and key retention features during the fabrication phase to guarantee a secure fit with your wheel center and axle assembly.
• For on-site customization projects, maintain rigorous measurement discipline and document any deviations to support repeatable manufacturing outcomes.

Brand reliability and craftsmanship

Trojan has a long-standing reputation for practical, durable wheel components used in both automotive and trailer contexts. This Hub Blank 225mm embodies Trojan’s engineering ethos: a solid, accurately-sized base designed to empower builders and restorers to achieve precise, reliable results without unnecessary constraints.
