Overview: 1/8-scale pinion

The MG5020TS pinion serves as an aftermarket motor pinion for 1/8-scale ARRMA and TRAXXAS vehicles, aimed at reliable power transfer in model drivetrains. It is made from 20Cr steel with a hardened black finish to resist wear more effectively than many softer stamped parts.

Core specs include 20 teeth, a 1.0mm module, and a 5.0mm round motor bore. Attachment uses two 4x4 set screws; make sure your motor flange and shaft match these parameters for correct installation.

For gearing changes this pinion offers a durable option where consistent mesh is needed. Match module, tooth count, and bore to your existing spur gear and motor before committing to the swap.

How will switching to this 20T pinion affect overall gearing?

Changing pinion tooth count alters final drive ratio; increasing teeth raises top speed and reduces torque at wheels, while fewer teeth increase acceleration. Always recalculate ratio using your spur tooth count before changing pinions.

What are the recommended installation steps?

Check module and bore compatibility, mount the pinion on the motor shaft, tighten the two 4x4 set screws evenly, rotate the motor and inspect mesh, then recheck screws after a short run.
