Eliminate the most common failure point in your Mini-Z's steering system with this Brass 4th Servo Gear. In the complicated geartrain of the MR-03 and MR-04 servo, the "4th Gear" is the final gear in the chain. It is the one that takes the direct impact force from the wheels when you crash.
The stock plastic gear often strips its teeth during hard impacts, leaving you with a car that steers crooked or not at all. This replacement is CNC machined from high-strength Brass, ensuring that your steering will survive heavy crashes and continue to operate smoothly for seasons to come.
Key Features
-
High-Strength Brass: Unlike the stock plastic gear which can shear under load, brass is incredibly durable.
It will not strip, even if you hit a wall at full speed. -
Precision CNC Machined: The teeth are cut (not molded) to exact tolerances. This ensures a silky smooth mesh with the other gears in the cluster, reducing the "notchy" feel sometimes found in worn steering systems.
-
Impact Resistance: As the final gear before the servo saver, it absorbs the shock energy traveling from the front wheels back into the servo.
-
Improved Centering: The rigidity of brass prevents the gear from flexing under load, which can help the steering center more accurately and consistently.
Compatibility
-
Chassis: Fits Kyosho Mini-Z MR-03 and MR-04.
-
Position: This is the 4th Gear only (the large final gear).
-
Mating Gears: Designed to mesh perfectly with the standard stock plastic gears (1st, 2nd, and 3rd) or PN Racing Delrin replacement gears.
