Overview
The ARRMA Composite Pivot Ball set is an essential replacement part designed for serious RC enthusiasts and weekend bashers alike who own ARRMA 4x4 BLX 4S models. Whether you are running a 1/10 Kraton 4S speed monster truck or a 1/10 OUTCAST 4S stunt truck, this high-quality suspension component set ensures your RC car UK setup maintains optimal performance and durability. Pivot balls are critical suspension parts that allow for smooth articulation and movement within your RC vehicle's suspension linkage system. When these parts wear out or break due to impacts and intense bashing, having quality replacement pivot balls becomes essential to maintain the handling characteristics and longevity of your brushless RC truck.
This composite pivot ball set from ARRMA provides a comprehensive replacement solution, giving you all the pivot balls needed to fully service your suspension system without the need to purchase multiple individual kits. The precision engineering behind these components ensures that assembly is straightforward and that your RC car performs as the manufacturer intended. For those investing in a ready to run RC car or building a competitive setup, maintaining your suspension with genuine ARRMA parts is a wise decision that will pay dividends in reliability and performance on the track or bash course.
Key Features
- Composite Material Construction — These pivot balls are manufactured from composite materials that provide long-lasting durability and increased impact resistance compared to standard plastic alternatives, meaning they can withstand the demands of aggressive bashing and competition use without cracking or splitting under pressure.
- Precision Manufactured Components — Each pivot ball is precision engineered to exacting tolerances, ensuring fast and easy assembly when replacing worn or damaged suspension linkage parts, which means less time troubleshooting and more time enjoying your brushless RC truck.
- Comprehensive Kit Contents — Rather than purchasing individual pivot ball types separately, this set includes all three types of pivot balls you need: suspension link pivot balls, shock pivot balls, and steering link pivot balls, making it a complete suspension refresh solution.
- OEM Compatibility — These are official ARRMA parts designed specifically for 4x4 BLX 4S models, guaranteeing perfect fit and function with your Kraton 4S or OUTCAST 4S without any modification or fitment issues.
- Impact Resistance — The composite material formulation provides enhanced impact resistance, which is crucial for RC vehicles that experience regular hard landings, jumps, and collisions during aggressive driving sessions.
Technical Performance
The ARRMA Composite Pivot Ball set represents quality engineering that addresses the specific suspension requirements of ARRMA's premium 4x4 BLX 4S platform. These pivot balls are the connection points that allow your suspension arms, shock towers, and steering linkages to move freely whilst maintaining structural integrity under the extreme forces generated by a brushless 4S LiPo power system. The composite material used in their construction offers the ideal balance between strength and longevity, resisting the cumulative wear that comes from thousands of cycles through suspension articulation. Unlike cheaper plastic alternatives that can become brittle or develop stress cracks, ARRMA's composite formulation maintains its properties through extended use, even in harsh outdoor conditions. The precision manufacturing ensures that each ball maintains consistent dimensions, which is critical for suspension geometry and prevents the loose, sloppy handling that develops when pivot balls wear out. For users of the Kraton 4S or OUTCAST 4S, maintaining the suspension system with genuine ARRMA parts ensures the vehicle continues to deliver the performance characteristics that make these platforms popular among UK RC enthusiasts.
