This is a processed G-22 pink gear spur gear for Mini 4WD double-shaft motors. The gear play and looseness are eliminated, so motor power is directly transmitted to the tires. Acceleration after landing and cornering speed improve. Adjust the gear backlash with a flexible chassis or counter shaft, etc. This product is processed from a new gear. *During processing, applying too much pressure can warp the gear, causing wobble during rotation. Each one is carefully finished, and we check for wobble during rotation before shipping. Highly praised by buyers. Get a 100 yen discount when you purchase 2 or more sets. The gear is designed to be fixed, but it will not get stuck with normal or hollow shafts. You can easily change tires and shafts even during a race. Processed to fit normal, hollow, and titanium shafts. When used with black shafts, there is no play, but the gear cannot be fixed. Instant purchase and no comments are okay.
