The Tamiya 84081 Aluminum Hi-Torque Servo Saver Horn is a solid upgrade for hobbyists looking to tighten steering feel on M03 and M04 chassis. Made from machined aluminum, this servo saver horn increases structural strength and gives a more direct response from the steering system during aggressive driving.
Compared with standard plastic parts, this aluminum unit stands up better to repeated loads and reduces flex that can dull steering feedback. That durability makes it suitable for high-torque setups and frequent track use while maintaining precise control.
Installation is straightforward when used with either the Tamiya 50473 Hi-Torque Servo Saver or the 51000 Hi-Torque Servo Saver (Black). The part is engineered for a reliable fit on M03 and M04 chassis so you can swap it in with basic tools.
