Yeah Racing Spring Steel CVD Driveshafts 2Pcs for Tamiya XV-02

High-performance CVD (Constant Velocity Drive) Driveshafts allow a driveshaft to efficiently transfer power at a variable angle, at constant rotational speed, without an appreciable increase in friction or play. The reduction in friction provides a damping effect on the suspension system and can improve handling on rough terrain, and at high speeds.
