TT-02 / XV-02 Aluminum Front Direct Coupling (Spool) Set, 39T

Upgrade your XV-02 with this Hop-Up Option set to enhance acceleration on low-grip surfaces and improve stability under braking. This set replaces the stock oil-filled gear differential with a front direct coupler (spool), eliminating differential action at the front. As a result, the car gains stronger forward drive and more stable braking, since both front wheels rotate at the same speed. However, this setup reduces cornering rotation, making it ideal for certain rally track conditions. Choose this upgrade based on your driving style and track layout for optimal performance.
