Injora Standard, Overdrive, and Underdrive Steel Helical Gears for the Traxxas TRX-4M
Injora has released a new series of Steel Helical Gears for the Traxxas TRX-4M. Whether you want a replacement for the TRX-4M’s stock, plastic gears, or you’d rather apply overdrive or underdrive to your small-scale crawler, these gear options should have you covered.
While there are other ways to adjust the speed and torque of your TRX-4M, these gears apply change at the axles. By adding overdrive gears to the front differential, you can increase your front-wheel spinning speed by roughly 9%.
Alternatively, you can add underdrive gears to the rear diff to decrease your speed by an estimated 9% or 16.67% (depending on the gear set).
These gears are made from CNC-machined alloy steel and offer improved durability and longevity compared to the stock, plastic gears.
