These are high-speed, low-friction gears ✨️, created using my experience with flat races and fence cars. Many others are selling similar items, but mine are designed for use in mini 4WD, maintaining torque transmission while also being suitable for layouts with elevation changes. After 50 sets of trial and error, I've adopted the ones that provided the best acceleration, so please give them a try ✨‼️ They perform best when combined with the motor pin shafts I'm selling and the SLIP STREAM070‼️ I also welcome bulk purchases ✨️ Get 5% off for bulk purchases & follows‼️ #Mini4WD #Gears #Processed #FinishedProduct #MS #MA #MachDashMotor #HyperDashMotor #TorqueTuneMotor #PowerDashMotor #Oil #BrokenIn
