Protect the gears inside your R/C cars’ steering servo with this Hi-Torque Servo Saver. During the rigors of R/C driving, the steering servo can experience sudden shocks and vibrations, which can damage servo gears. The Tamiya Hi-Torque servo saver uses a spring type mechanism that helps prevent straining the internal gears inside the servo during hard impacts and rigorous driving. This specific set comes molded in white.
