Overview
The Fastrax Ball Cups (4) Blue w/Ball Studs FAST45B are essential replacement and spare parts for RC car enthusiasts across the UK who demand reliability and precision in their hobby builds. Whether you're maintaining your current RC vehicle or upgrading components on your latest purchase, these ball cups represent Fastrax's commitment to quality engineering and compatibility. As an RC car UK hobbyist, you'll appreciate components that fit perfectly and perform consistently, and these ball cups deliver exactly that standard of reliability.
Ball cups and ball studs are critical suspension components that connect your RC car's suspension arms to the main chassis and steering components. The FAST45B set includes four complete ball cup assemblies with integrated ball studs, providing you with everything needed to refresh worn suspension joints or complete a repair on your ready to run RC vehicle or custom build. These are the kinds of replacement parts that separate casual RC enthusiasts from those who maintain their equipment to competition standards, ensuring smooth steering response and reliable suspension geometry.
Fastrax has established itself as a trusted manufacturer of quality RC spares and accessories, and these ball cups exemplify their attention to detail. The blue colour adds a touch of visual customisation to your RC setup while maintaining the functional excellence you need for consistent on-track or off-road performance.
Key Features
- 4.8mm Ball Design — The 4.8mm ball specification is engineered to provide a secure, low-friction connection point in your RC car's suspension system, allowing smooth articulation and responsive handling characteristics that directly affect steering precision and cornering performance.
- 3mm Screw Thread — The 3mm screw thread ensures compatibility with a wide range of RC car platforms and makes installation straightforward, allowing you to quickly replace worn ball cups or upgrade suspension components without requiring special tools or adapters.
- Four-Piece Set — This pack includes four complete ball cup assemblies with ball studs included, providing you with a full set for either a complete suspension refresh on a four-wheel RC vehicle or to have spares on hand for future maintenance and repairs.
- Fastrax Quality Engineering — Fastrax manufactures these components to consistent standards, ensuring that ball cups fit reliably and perform predictably across multiple RC car types and driving conditions, whether you're a weekend basher or serious racer.
- Blue Colour Finish — The distinctive blue anodised finish not only provides visual appeal and customisation options for your RC build, but also helps protect the metal components from corrosion and wear during regular use.
Technical Performance
These ball cups represent solid engineering for suspension maintenance and upgrades on RC cars. The 4.8mm ball size is a standard specification across many RC vehicle platforms, ensuring compatibility with popular ready to run RC models and custom builds alike. The 3mm screw thread allows these ball cups to integrate seamlessly into existing suspension designs without requiring modification or adapter components. The inclusion of ball studs means you receive complete assemblies rather than just the cups, reducing the complexity of installation and ensuring proper fit. The anodised blue finish provides durability against the corrosion that can develop during regular RC car use, particularly in wet or humid UK conditions. Whether you're replacing suspension components that have worn from extensive driving or building a new RC car from the ground up, these ball cups offer the reliability and precision that dedicated RC enthusiasts expect from Fastrax products.

Frequently Asked Questions
- What are ball cups used for on an RC car? — Ball cups are suspension joints that connect your RC car's suspension arms and steering components to the main chassis. They allow smooth articulation of the suspension while maintaining precise geometric alignment, which directly affects steering response, handling balance, and overall vehicle control during driving.
- Are these ball cups suitable for all RC car types? — The 4.8mm ball and 3mm screw thread are standard specifications found on many RC car platforms, though you should verify compatibility with your specific vehicle model before purchasing. These dimensions work with a wide range of ready to run RC cars and custom builds from various manufacturers.
- How often should I replace ball cups on my RC car? — Ball cup wear depends on driving intensity, surface conditions, and maintenance practices. Regular inspection will reveal when ball cups have developed play or worn surfaces, at which point replacement improves handling precision and steering response. Having spare ball cups on hand means you can perform maintenance quickly without waiting for parts to arrive.
- Why are four ball cups included in this set? — Four ball cups allow for a complete suspension refresh on a typical four-wheel RC car, with one set per wheel corner, or provide comprehensive spares for multiple repairs and maintenance cycles on your vehicles.
- What is the difference between these and other ball cup options? — Fastrax manufactures these components to consistent engineering standards and includes the ball studs as complete assemblies, reducing installation complexity and ensuring proper fit across multiple RC platforms. The anodised blue finish offers both durability and visual customisation.
