Trojan 225mm Wheel Hub Blank for Stud Holes – 5x4.5" Slimline No Disc

Engineers and wheel enthusiasts who require exacting control over mounting geometry will appreciate the Trojan 225mm Wheel Hub Blank for Stud Holes. This purpose-built base is designed to accommodate non-standard bolt patterns, enabling precise configuration of your own wheel stud pattern. Built to be a stable, flat mounting surface with a centered boss, it supports accurate alignment during drilling and assembly—an essential foundation for custom wheel builds, hub conversions, and restoration projects where off-the-shelf hubs simply don’t fit.

Key advantages that set this hub blank apart

• 225 mm hub face designed to provide a robust, roomy mounting platform for precise stud placement and reliable bolt-circle symmetry.
• 5x4.5" bolt pattern compatibility for versatile wheel options and the ability to tailor patterns to your vehicle or project.
• Slimline, no disc design to simplify retrofits and configurations where a separate disc is mounted elsewhere or not required.
• Centered boss and true reference surface to simplify alignment, reduce runout, and improve drilling accuracy when you fixture the blank in a lathe or dedicated jig.
• Drill-ready for precise stud holes with a dedicated process to achieve clean, evenly sized openings tailored to your pattern.

Drilling and setup you can trust

The Trojan hub blank is built for accuracy from the first siting in your fixture. A dedicated drilling workflow ensures you establish a true reference surface and use consistent measurements as you mark hole locations. A 13.75 mm drill bit is the recommended size for creating the stud holes, delivering clean openings that maintain concentricity and balance once the studs are installed. This approach helps minimize misalignment that can impact wheel runout and overall handling.

How to use it (quick guide)

• Secure the blank firmly in a fixture or lathe to prevent any movement during drilling.
• Mark the stud locations according to your target 5x4.5" pattern and bolt-circle geometry.
• Drill each hole to 13.75 mm with care to maintain clean, straight openings.
• Recheck alignment and bolt-circle symmetry before final assembly to ensure optimal wheel stability and road manners.

Who should consider the Trojan 225mm Wheel Hub Blank?

This part is ideal for pro mechanics, tuners, and DIY enthusiasts who demand exacting control over wheel mounting geometry. It’s particularly valuable when upgrading to non-standard wheel patterns, retrofitting wheels to classic or bespoke hubs, or restoring setups where a predrilled hub blank provides the most reliable path to a safe, balanced result. By starting with a dedicated hub blank, you gain repeatable accuracy and a solid foundation for quality, long-term performance.
