The Tamiya 50940 Ball Differential Joint Cup Set is purpose-made for the F201 chassis, supplying a sturdy upgrade for racers who want predictable handling. The black aluminium construction balances toughness with minimal added mass.
Constructed from black aluminium, these cups resist abrasion from frequent runs and keep the front end stable. The combination of lightness and strength helps preserve the chassis balance under load.
The set includes two cups: a left cup 26.5mm long by 20mm diameter and a right cup 27mm long by 20mm diameter. These exact sizes reduce unwanted movement and let the ball differential operate smoothly.
