Technical Performance
The ball differential is a critical component in any 1/10 scale 2WD off-road RC buggy, responsible for distributing power smoothly between the rear wheels during cornering and acceleration. The Team Associated B6/B7 ball differential system features carefully engineered ball races and components that work together to provide optimal traction and stability characteristics across different track conditions. The caged race configuration employed in this rebuild kit specifically addresses the performance requirements of competitive racing, where smooth, predictable differential action can mean the difference between winning and losing. By performing regular maintenance with this genuine Team Associated rebuild kit, you ensure that your differential maintains its factory specifications and performance characteristics. The kit is designed to work seamlessly with the rest of your RC10 B6 or B7 chassis, which features a lightweight hard-anodised aluminium construction with centralised mass for improved handling on all track types, paired with a robust 3-gear transmission that emphasises acceleration and responsive handling. Whether you're running your RC buggy on loose dirt, clay, or clay-based competition tracks, maintaining your differential in top condition is essential for consistent lap times and reliable performance.
