The 416-12/LB solid axle is a scale driveline replacement engineered for use with the TAMIYA TRF 416 chassis, intended as a direct-fit component for detailed setup work.
As a tuning element it modifies rear driveline stiffness and load transfer characteristics, providing a platform for measured adjustments to chassis balance and cornering behaviour. Install at the designated axle location on the TRF 416 and retain factory mounting geometry to preserve intended suspension kinematics.
Prior to final assembly verify the 416-12/LB part number against your TRF 416 variant and check for correct alignment and axle housing clearances. Adhere to standard RC assembly procedures and torque specifications when replacing driveline hardware to ensure repeatable performance.
