Overview
The ARRMA Pivot Ball M4x11x15.4mm (2) Z-ARA330563 is an essential suspension spare part designed for high-performance RC monster trucks. These precision-engineered pivot balls are critical components in the suspension system of your brushless RC car, maintaining smooth articulation and responsive handling characteristics that serious RC enthusiasts demand. Whether you're a weekend basher enjoying the thrills of an RC monster truck in the UK or a dedicated racer pushing your vehicle to its limits, having quality replacement pivot balls on hand ensures your rig stays in peak condition for every outing.
This genuine ARRMA spare part is purpose-built for the 1/5 scale Kraton and Outcast 8S models, two of the most capable and popular brushless monster trucks on the market today. The Kraton 4X4 8S BLX EXB and Outcast 4X4 8S BLX EXB are renowned for their aggressive performance and durability, and these pivot balls play a vital role in delivering the smooth suspension articulation that makes these vehicles so fun to drive. RC enthusiasts across the UK who own these 8S brushless platforms understand that maintaining suspension integrity is key to consistent handling and longevity.
Suspension components like pivot balls experience significant wear through regular use, particularly if you frequently bash your RC car off-road or compete in high-intensity racing. Having a spare set of two pivot balls ensures you can quickly perform maintenance or repairs without lengthy downtime. The M4x11x15.4mm specification represents the precise engineering that ARRMA builds into every component, delivering the exact fit and performance required for optimal suspension geometry and response.
Key Features

- Precision M4x11x15.4mm Specification — These pivot balls feature exact dimensions that match the factory suspension design of your RC monster truck, guaranteeing seamless integration and optimal performance. The specific size is critical for maintaining proper suspension articulation and handling characteristics that define responsive RC driving.
- Pack of Two Units — You receive two pivot balls in this package, allowing you to replace both sides of a suspension joint or maintain a spare set for future maintenance. Having multiple units means you can keep your monster truck running whilst servicing other components.
- Essential Suspension Spare — Pivot balls are fundamental to suspension function in modern RC trucks, connecting control arms and suspension links whilst allowing smooth articulation over rough terrain. Regular inspection and replacement of worn pivot balls is essential for maintaining handling precision and ride quality.
- Compatible with Elite 8S Platforms — Specifically engineered for the ARRMA 1/5 Kraton 4X4 8S BLX EXB and the ARRMA 1/5 Outcast 4X4 8S BLX EXB, these pivot balls ensure your brushless monster truck maintains factory suspension performance and articulation characteristics.
Technical Performance
The ARRMA Pivot Ball Z-ARA330563 represents precision engineering designed specifically for the demands of high-performance 1/5 scale RC monster trucks. The M4x11x15.4mm dimensions are engineered to exacting tolerances, ensuring that suspension geometry remains consistent and that articulation remains smooth even under the extreme forces generated by brushless 8S platforms. The Kraton and Outcast 8S models utilise these pivot balls as critical connection points within their suspension systems, allowing the control arms and suspension links to move freely whilst maintaining precise alignment. These components experience significant stress during aggressive driving, jumps, and rough terrain negotiation, which is why genuine ARRMA spares maintain the exact specifications required for optimal performance. Regular inspection and timely replacement of pivot balls is part of essential RC car maintenance, particularly if you notice any play in the suspension or hear clicking sounds from the suspension joints. Keeping these components in good condition directly affects handling response, steering precision, and the overall durability of your brushless RC monster truck investment.

Frequently Asked Questions
- What are pivot balls and why do they matter in RC monster trucks? — Pivot balls are spherical joints that connect various suspension components, allowing smooth articulation whilst maintaining suspension geometry. In a 1/5 scale brushless RC monster truck like the Kraton or Outcast 8S, pivot balls are subjected to significant forces during driving, jumps and rough terrain use. When they wear out, you may notice loose suspension, poor handling response, or clicking sounds from the suspension. Replacing them with genuine ARRMA spares restores suspension performance and responsiveness, which is why many UK RC enthusiasts keep spare pivot balls in their maintenance kit.
- Are these pivot balls compatible with my ARRMA RC truck? — These Z-ARA330563 pivot balls are specifically designed for the ARRMA 1/5 Kraton 4X4 8S BLX EXB and the ARRMA 1/5 Outcast 4X4 8S BLX EXB brushless monster trucks. If you own either of these 8S platforms, these genuine spares will fit perfectly and maintain factory suspension specifications. Always verify your model before ordering RC spares to ensure correct compatibility.
- How often should I replace pivot balls on my RC car? — The frequency of pivot ball replacement depends on how frequently and intensively you use your RC monster truck. Weekend bashers might replace them every 6-12 months, whilst competitive racers or heavy users may need replacements more frequently. Regular inspection of your suspension joints will reveal when wear becomes noticeable, indicated by play in the joints or clicking sounds during articulation. Keeping spare pivot balls on hand means you can perform maintenance without waiting for delivery.
- Can I use these pivot balls on other ARRMA models? — These M4x11x15.4mm pivot balls are engineered specifically for the Kraton and Outcast 8S platforms. Whilst other ARRMA models may use similar components, the exact dimensions and specification are critical for proper fit and performance. Always check your vehicle manual or contact an authorised retailer to confirm compatibility before ordering suspension spares for a different ARRMA model.
