- 18mm Pivot Ball Design — The 18mm size is specifically engineered for ARRMA's 1/5 scale suspension geometry, providing the correct pivot point and contact surface for smooth articulation and precise steering response in all driving conditions.
- M8x25mm Specification — The M8 thread diameter and 25mm length ensure perfect compatibility with ARRMA Kraton and Outcast 8S suspension linkages, bell cranks, and pivot points without requiring any modifications or adaptations.
- Pair of Two Units — You receive two pivot balls in this package, which is typically the quantity needed for complete suspension overhaul or replacement, reducing the need for multiple orders when maintaining your RC vehicle.
- Suspension Spares Category — As a dedicated suspension component, this part is engineered specifically for the suspension system of your ARRMA 4x4 vehicle, where pivot ball performance directly affects handling accuracy and vehicle stability.

Technical Performance
The ARRMA 18mm Pivot Ball M8x25mm represents precision engineering at the component level, manufactured from high-grade materials selected to withstand the extreme stresses of 1/5 scale RC driving. The 18mm diameter ball size is specifically calculated to match ARRMA's suspension linkage geometry, ensuring proper articulation angles and maintaining the vehicle's intended handling characteristics whether you're driving an ARRMA Kraton 8S or Outcast 8S. The M8x25mm thread specification provides a robust connection point that reliably transfers suspension forces whilst maintaining accurate pivot geometry under acceleration, cornering, and off-road impacts. Quality pivot balls are critical in RC vehicle suspension because they permit smooth articulation of control arms and linkages whilst maintaining precise alignment—any wear or degradation results in loose, unpredictable handling and reduced control authority. By fitting genuine ARRMA replacement pivot balls, you're restoring your suspension to factory specifications and ensuring that the sophisticated suspension tuning engineers have designed for your vehicle actually works as intended. These components are essential for any RC enthusiast who values consistent handling, maintains their vehicle regularly, or drives in competitive environments where suspension integrity directly impacts lap times and overall performance.

Frequently Asked Questions
- Which ARRMA models use the 18mm Pivot Ball M8x25mm? — This pivot ball is specifically designed for the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck and compatible ARRMA Kraton 8S models, making it essential for anyone running these high-performance brushless RC vehicles.
- Why do I need to replace my RC pivot balls? — Pivot balls wear over time due to constant stress from suspension articulation, impacts, and driving forces, causing them to lose their spherical shape and resulting in loose, unpredictable steering and handling. Regular replacement keeps your suspension geometry accurate and your vehicle handling crisp and responsive.
- Are these compatible with my ARRMA RC truck? — These pivot balls are designed for ARRMA Kraton and Outcast 8S models; however, we recommend confirming your specific model number matches the C-ARA5810V2T1 platform to ensure perfect compatibility.
- How often should I replace pivot balls on my RC car? — The replacement frequency depends on driving intensity and conditions, but regular inspection is recommended. If you notice loose steering, unresponsive handling, or visible wear on the ball surface, replacement is necessary to maintain performance and safety.
- What tools do I need to install these pivot balls? — Installation typically requires basic RC tools including hex wrenches and possibly a small wrench for the M8 thread, depending on your suspension linkage configuration and how the balls are mounted on your specific model.
