Attention RC enthusiasts and Tamiya builders! Looking to fine-tune the performance of your M-06, M-05, or M-05RA chassis? This Ball Differential Set is the precision upgrade you've been looking for. A ball differential helps provide smoother power transfer and more controlled handling compared to a standard gear diff, especially when coming out of corners. It allows the driven wheels to rotate at different speeds, which is crucial for better traction and overall driveability. This isn't a toy—it's a serious tuning part for hobbyists who love to build, tweak, and optimize their remote control cars. Please note, due to small parts and the complexity of assembly, this set is not suitable for children under 14 years old. It's perfect for the experienced builder wanting to get the most out of their Tamiya mini on-road or rally car. Installation requires some mechanical know-how, but it's a rewarding project that can really elevate your car's performance. Grab this set and feel the difference in your next race or casual run!
