Aluminium Alloy Fork Cup Pair: CNC Machined Axle Cups for Electric Car and Motorcycle Front Axles

This pair of fork cups is designed as a direct replacement or accessory component for the front axles of electric vehicles and motorcycles. Manufactured from aluminium alloy via a CNC (Computer Numerical Control) process, each cup is produced to precise tolerances, ensuring a consistent and accurate fit for axle nuts or fasteners. The primary application is for vehicles where the front axle screw specification is less than M14, covering a range of common models. The product undergoes an anodic colouring process, resulting in a durable surface finish available in several distinct colours. Supplied as a complete pair, these cups offer a practical solution for axle assembly, with the entire package weighing 120 grams.

Features and Construction

The fork cups are defined by their material choice and manufacturing method, which directly influence their fit and finish. This section details the build quality and the resulting product specifications.

Material and Build

The core material is aluminium alloy, selected for its favourable strength-to-weight ratio, making it suitable for non-structural axle components. The manufacturing process is CNC machining, which removes material from a solid billet to create the final cup shape. This method allows for high precision and repeatability in the product's internal and external dimensions, which is critical for a secure fit on the axle. Following machining, the cups receive an anodic colouring treatment. This electrochemical process increases surface hardness and corrosion resistance while dyeing the aluminium oxide layer, creating the permanent blue, gold, orange, red, or silver finishes.

Size and Practical Fit

The key specification for fitment is that the cups are compatible with front axle screws having a diameter of less than M14. This measurement refers to the metric screw thread size, indicating the cups are intended for axles with a thread major diameter under 14 millimetres. While exact cup dimensions are not provided, the CNC process ensures that all units match the designed specifications precisely. The product is supplied as a pair, ensuring you have both the left and right side cups required for a front axle. The total weight, including all packaging, is confirmed as 120 grams (0.12 kg), reflecting the light nature of the aluminium construction.

Uses and Placement

These fork cups serve a specific mechanical function within a vehicle's front axle assembly. Their use is tied directly to the type of vehicle and the axle's technical specifications.

Event or Professional Use

For professional mechanics, custom bike builders, or electric vehicle technicians, these cups provide a reliable, precisely made component. The CNC accuracy ensures minimal fitting issues during assembly or repair jobs, saving time on modifications. The anodised finish is more resistant to scratches and wear from handling than plain aluminium or paint, maintaining a professional appearance in a workshop setting or on a finished custom build. The colour options allow for aesthetic matching or accenting on show vehicles or branded fleet electric scooters.

Everyday Home Use

For the individual vehicle owner performing their own maintenance, these cups offer a straightforward replacement part. The clear specification (fits screws less than M14) allows an owner to check their vehicle's manual or measure their existing axle nut to confirm compatibility before purchase. The durable anodised finish means the cups will retain their colour with minimal care, resisting fading from sunlight or light cleaning. As a pair is included, the user has all necessary parts for a standard front axle refresh without needing to buy separate left and right components.

Benefits and Buying Value

The value of this product lies in its defined compatibility, construction method, and finish options. It addresses specific needs without promising unsupported performance enhancements.

Reuse and Low Maintenance

The anodised aluminium construction contributes to the product's potential for reuse and low upkeep. Anodising creates a hard, integral surface layer that is more resistant to chipping and corrosion than paint or powder coating. This means the cups can be removed and reinstalled multiple times with a lower risk of finish damage, making them suitable for projects where components are frequently adjusted. The aluminium material itself does not rust, and any general dirt can be wiped clean with a damp cloth without requiring specialist cleaners or polishes.

Why Choose This Product

This fork cup set is a match for buyers who have verified their vehicle's front axle screw size is under M14 and are seeking a precisely manufactured component. The choice of CNC machining over casting typically results in better dimensional accuracy and a stronger part free of porosity. The range of anodised colours (blue, gold, orange, red, silver) provides an opportunity for personalisation or colour-coding that is more durable than adhesive labels or paint. The product delivers a defined set of features—material, process, colour options, and compatibility—for a clear, practical axle application.
