Key Features
- Tough Composite Material — The ball cups and balls are manufactured from durable composite material that provides excellent strength-to-weight ratio and long-lasting durability in all driving conditions, meaning you can bash hard without worrying about premature wear or failure.
- Precision Manufacturing — Each ball cup and ball is manufactured with precision tolerances to ensure a slop-free ball-to-cup fit, which is essential for maintaining accurate suspension geometry and consistent handling performance across every drive session.
- Complete Set — This set includes four ball cups and four pivot balls, providing everything you need to replace worn suspension components or complete a full vehicle build with the correct number of parts for your ARRMA RC car.
- Wide Vehicle Compatibility — The Z-ARA320501 is compatible with multiple ARRMA vehicle models, including the Felony 6S BLX, KRATON 6S EXB, LIMITLESS 8S AVC, and TALION 6S EXB, making it a practical spare for anyone with ARRMA RC vehicles in their collection.
- Essential Replacement Part — Ball cups and balls are critical suspension components that experience wear over time, and having quality replacements on hand ensures you can keep your RC car performing optimally without extended downtime.
Technical Performance
The ARRMA Ball Cup and Balls Z-ARA320501 represents precision engineering in suspension maintenance for RC vehicles. Constructed from tough composite material, these components are engineered to withstand the stresses and impacts inherent in RC driving, whether you're operating a brushless RC speed monster truck, a championship-level RC buggy, or any other ARRMA-compatible vehicle. The composite material selection provides an optimal balance between durability and weight, ensuring your suspension operates efficiently without adding unnecessary mass to your chassis. The precision manufacturing process ensures that each ball cup maintains exact tolerances, creating a slop-free connection with the pivot ball. This is absolutely critical for RC performance, as any play in the suspension ball joints can lead to inconsistent handling, unpredictable behaviour under cornering, and difficulty maintaining accurate vehicle control during high-speed runs or technical courses. The set includes four complete ball cup and ball assemblies, which is the standard configuration for most RC vehicles that use ball cups in their suspension geometry. Whether you're rebuilding your suspension after heavy use, replacing components damaged during competitive racing, or assembling a new RC car UK model from individual parts, this complete set ensures you have everything needed for proper suspension function. ARRMA's reputation for engineering excellence is reflected in every aspect of this part, from material selection to manufacturing precision.

Frequently Asked Questions
- What are ball cups and why do I need them in my RC car? — Ball cups and balls are critical suspension components that connect the suspension arms to the chassis through ball joints, allowing smooth articulation and maintaining proper geometry. Over time, these components wear from constant movement and impacts, and replacing them with fresh parts ensures your suspension operates smoothly and your RC car maintains consistent handling characteristics.
- Are these compatible with my ARRMA RC car? — The Z-ARA320501 is compatible with a range of ARRMA models including the Felony 6S BLX in both Orange and Black variants, the KRATON 6S EXB 4X4 RTR Speed Monster Truck in Black, the LIMITLESS 8S AVC 4X4 RTR BLX Street Speed in both White/Blue and Red/Black variants, and the TALION 6S EXB 4X4 RTR Speed Truck in Black. If you own any of these vehicles, this part will fit correctly.
- How often should I replace my ball cups and balls? — This depends on how frequently and intensively you use your RC car. Regular bashers might need replacement every few months, whilst competitive racers might need them more frequently. If you notice play or slop in your suspension, or if your RC car's handling feels inconsistent, it's time to replace the ball cups and balls.
- What is the difference between these composite ball cups and metal alternatives? — These composite ball cups offer excellent durability whilst maintaining a lightweight construction, which is ideal for most RC applications. Composite material also provides good impact resistance and doesn't corrode, making it a reliable choice for both on-road and off-road driving in all weather conditions.
- Will these work on other RC brands besides ARRMA? — These ball cups are specifically engineered for ARRMA vehicles and are not guaranteed to be compatible with other brands. Always check compatibility with your specific vehicle before purchasing replacement parts to ensure proper fit and function.
