Yokomo B9-501GAA Aluminum drive cup for BD9 Gear diff 橫崛 Yokomo MSR-BDFWD  [B9-501GAA]

This is an aluminum joint cup for the gear differential that is standard equipment on BD9. It is specially designed for specifications that require a resin protector to be attached to the universal shaft side, and is also hard anodized to minimize wear.
It is lighter than standard steel and is effective in increasing drive efficiency and acceleration response. In addition, by making the rotating parts lighter, the gyroscopic effect is also reduced, which is effective in improving exercise performance.
