INJORA Overdrive Underdrive Alloy Steel Helical Gears for 1/18 TRX4M

INJORA has introduced a set of Overdrive Underdrive Alloy Steel Helical Gears specifically designed for 1/18 RC crawler TRX4M. These gears are a great replacement for stock plastic gears and offer greater strength and smooth operation. The helical gears are CNC machined from 20CrMo Alloy Steel that reduces vibration, noise and wear compared to the stock gears.

The set includes a ring gear and a pinion gear and should be used together in each axle. It is important to note that these gears cannot be interchanged with gears from different gear sets, even if they have the same number of teeth.

The 22T/10T Underdrive Gears decrease speed by approximately 9%, while the 24T/10T Underdrive Gears decrease speed by approximately 16.67%. The 24T/12T Gears do not change speed, and the 22T/12T Overdrive Gears increase speed by approximately 9%.

Upgrade your TRX4M with these high-quality helical gears to improve your RC crawling experience.
