Hub - 225mm - 5 x 4-1/4" x 7/16" - No Disc

The Trojan Hub Blank 225mm is a precision-engineered wheel hub blank designed for professional fabrication, restoration, and custom wheel projects. With a 225mm hub diameter and a 5x4-1/4" bolt pattern, this blank provides a solid, study foundation for creating exacting, race-ready wheel assemblies. The design is intentionally provided as a “No Disc” hub, giving you full freedom to specify rotor mounting, caliper spacing, and disc interface to match your unique build.

Key benefits that matter in real-world builds

• Exact foundational platform: 225mm hub diameter ensures compatibility with a wide range of drum/rotor configurations and gives you a reliable starting point for precise alignment.
• 5x4-1/4" bolt pattern: A common, versatile pattern for custom builds, enabling you to tailor stud layout to your wheel design without compromising strength or concentricity.
• No Disc out-of-the-box: By starting from a blank hub, you control rotor mounting geometry, hub flange position, and disc interface to suit non-standard or vintage patterns.
• Concentricity and precision bore: Built to minimize runout and ensure repeatable alignment across multiple builds, important for reliable wheel balance and performance.
• Professional-grade for restorations: An ideal choice for restoration shops and fabrication laboratories that recreate original patterns or engineer bespoke wheel systems on-site.
• Versatile for fabrication shops: Supports on-site customization, allowing machinists to drill, mill, and finish to exact customer specifications with confidence.

Who benefits most

Professional wheel builders, restoration specialists, and fabrication shops will find this Trojan hub blank a practical core component for bespoke wheel projects. It’s equally suited for custom hot-rods, vintage restorations, off-road builds, and any scenario where an exact, non-standard hub pattern is required.

How this hub blank solves common problems

• Non-standard patterns are accommodated without forcing a disc-to-hub compromise.
• On-site customization reduces pre-fabrication lead times and enables iterative testing of pattern fitment.
• Consistent foundation across builds minimizes misalignment and facilitates repeatable wheel assembly quality.
