Yokomo B9-207 4.8mm Ball End Cap Ball Cup (Hard)

The Yokomo B9-207 ball end cap is precision engineered for serious racers who demand consistent performance lap after lap. These hard compound ball cups deliver the durability you need when pushing your 1/10 scale touring car to its limits on high grip surfaces.

What makes these 4.8mm ball cups special is their resistance to wear under extreme steering loads. The harder material composition means they hold their shape longer than standard cups, giving you more predictable steering response throughout your run. You'll notice the difference especially during long A-mains when other cars start getting sloppy.

Installation is straightforward on both the Yokomo BD9 and A12X platforms. The tight tolerances ensure a secure fit on your turnbuckles without excessive play, yet they still allow smooth articulation through the full range of suspension travel. Many racers keep a set of these in their pit box as insurance against unexpected wear during race weekends.

Each package includes the ball end caps you need to refresh your steering or suspension linkage. Whether you're building fresh or maintaining your current setup, these are the same components Yokomo factory drivers rely on when podium finishes are on the line.
