Non standard spokes refer to a wheel spoke that does not comply with industry-standard specifications or dimensions, with its design, dimensions, materials, or performance parameters exceeding conventional standard ranges. It is a wheel spoke designed for special operating conditions, customised equipment, or non-standard vehicles. Anyang Wanyun Automotive Parts Co., Ltd. is a manufacturer with extensive experience in customising non-standard components. We offer customisation services, and you will need to provide drawings or detailed parameter information. Our professional team will provide customised products and services tailored to your specific requirements. Please feel free to contact us!

Key Features of Non-Standard Spokes

Non-standard spokes are engineered to meet unique structural, dimensional, and load-bearing requirements that cannot be satisfied by standard spoke designs.

Fully Customizable Geometry

Spoke profile, thickness distribution, and reinforcement zones can be tailored according to load conditions and installation constraints.

Non-Standard Dimensional Compatibility

Designed for irregular PCDs, oversized center bores, and special bolt configurations required by custom hubs and axles.

Enhanced Structural Strength

Optimized cross-sections and material selection improve resistance to impact loads, vibration, and long-term fatigue.

Drawing-Based Manufacturing

Production is based on technical drawings or confirmed parameters, ensuring precise fit for one-off or small-batch projects.

Flexible Material & Surface Options

Material grades and surface treatments can be selected according to environmental and operational requirements.

Application Scenarios

Modified Vehicles: Off-road enthusiasts often upgrade to oversized tires, requiring custom non-standard wheel spokes to match widened hubs and rims.
Customized Construction Machinery: Certain models of port cranes with unique axle spacing need non-standard spokes to adjust the track width and ensure equipment stability.
Maintenance of Outdated Equipment: For engineering vehicles that have been discontinued for years, standard spokes are no longer available on the market. In such cases, non-standard parts must be reproduced based on original factory drawings.

Customization Scope & Engineering Support

Non-standard spokes are typically supplied as project-based components rather than off-the-shelf products. Our engineering team supports customers throughout the customization process.
