The Tamiya 9803230 front direct cup is intended for use with the TRF420 chassis to increase drivetrain efficiency. Its role is to reduce drivetrain losses for steadier power delivery and improved on-track consistency.
Engineered for the TRF420, the direct cup lowers internal friction so torque reaches the front wheels more effectively. That gives drivers a more consistent throttle and steering relationship during aggressive runs.
Built to tolerate the stresses of competitive driving, this component helps maintain dependable performance through repeated sessions. Routine checks and correct lubrication will preserve its service life.
