Material, Color & Gear Details
Material and Color: Made from aluminum alloy, this material offers high strength and durability, effectively enhancing the axle's impact resistance and service life. The black and titanium colors provide the axle with a unique appearance, making it look more stylish, while also offering some rust-resistant properties, thereby enhancing both the aesthetic appeal and practicality of the component.
Gear Specifications: The marked “38T/13T” refers to the number of teeth on the internal gears of the axle. Typically, 38T refers to the number of teeth on the main gear, while 13T refers to the number of teeth on the driven gear. This gear ratio helps provide an appropriate transmission ratio, which affects the torque and speed of the climbing vehicle. A higher transmission ratio increases torque, enabling the vehicle to perform more powerfully when climbing steep slopes or navigating complex terrain.

Compatibility & Performance Upgrades
Compatible Models: Primarily compatible with various models of the SCX10 first generation, such as the classic models 90011, 90012, 90014, and 90016, as well as some other similar 1:10 scale remote-controlled climbing vehicles, such as the D90 model.
Performance Enhancements: Compared to stock axles, aluminum alloy axles reduce vehicle weight, improving handling performance and climbing agility. Additionally, metal gears are more durable than plastic gears, less prone to slipping or damage, enhancing the stability and reliability of the drivetrain system, enabling smoother operation on complex terrain.
