Trojan 160mm Wheel Hub Blank — 5 On 4.25 Bolt Pattern

The Trojan 160mm Wheel Hub Blank is a precision-engineered foundation for custom wheel assemblies within Trojan’s renowned wheel-system lineup. Designed to accommodate a 5-on-4.25 inch bolt pattern, this hub blank provides a reliable, concentric starting point for builders and technicians tackling bespoke wheel projects.

Why this hub blank stands out

• Exact 5 on 4.25 inch bolt pattern — A well-supported standard for light- to mid-duty applications, ensuring predictable fitment for drilled stud holes and subsequent wheel mounting components.
• 160mm hub diameter — A substantial, stable base that promotes proper alignment and reduces runout during installation and use.
• Trojan-grade consistency — Engineered to align smoothly with Trojan wheel-system components, delivering repeatable accuracy across builds and reducing rework.
• Designed for machining flexibility — Built to be prepared by a qualified machine shop for your chosen stud-hole configuration, enabling custom setups without compromising integrity.

What problems it solves

For builders and restorers, this hub blank minimizes guesswork when creating a new wheel hub assembly. Its precise diameter and bolt-circle geometry mean you can plan the drill pattern with confidence, achieving clean concentric mounting and dependable load distribution. This reduces misalignment risks, downtime, and the need for multiple mock-ups during a build.

Ideal use cases

• Custom wheel builds where a precise, bare hub base is required before drilling in the exact stud holes to the 5x108 mm (4.25 in) bolt circle.
• Restoration or adaptation projects that rely on Trojan wheel-system compatibility and consistent hub tolerances.
• Machine-shop or fabrication environments focusing on repeatable hub foundations for multiple vehicles or configurations.

Practical tips for installation and care

Engage a qualified machinist to verify tolerances and drill the stud holes to the target pattern. Use proper torque specs and, when applicable, appropriate anti-seize or lubrication to ensure smooth mounting and long-term reliability. Store the hub blank in a dry, clean area to prevent corrosion and inspect for any surface defects before use.

Brand and quality you can rely on
