Tamiya 54126 Center One-Way OP-1126 Track Tuning Part  [54126]

Dial in Your TB-03 with the Tamiya One-Way

The Tamiya 54126 Center One-Way OP-1126 upgrades the TB-03 chassis by providing locked drive when you apply throttle and free rotation when you lift off. This trade improves grip under drive and reduces instability during deceleration through corners.

Fitment and Exclusions

This Center One-Way is compatible with all TB-03 models but cannot be installed together with the TB-03 Aluminum Propeller Joint Set (Rear) or the TB-03 Aluminum Spur Gear Mount, so plan upgrades accordingly.

Included Parts and Function

The set includes the Center One-Way assembly, Center One-Way Shaft, 840 Flange Bearing, 1050 Bearing, a Urethane Bushing and two 2mm E-Rings. These parts ensure the one-way mechanism runs reliably and improves drive feel.
