Lightweight 21T Pulley for Front-Wheel Drive Models

The Arrowmax AM-920041 AM Medius FWD 21T pulley is crafted from Aium 7075 to offer a reliable, low-mass option for FWD RC cars. Its precise tooth form is intended to improve power delivery without adding unnecessary bulk to the drivetrain.

Why Aium 7075 Works Well

Aium 7075 provides a high strength-to-weight ratio that helps this pulley resist wear while keeping overall vehicle weight lower. That makes it a practical upgrade for both club runs and more demanding track days.

Engineered for Smooth Torque Transfer

This pulley suits front-wheel drive arrangements and is made to minimise slippage and vibration. The consistent engagement helps deliver smoother acceleration and steadier control through corners.

Can I swap this pulley into a stock gearbox?

In many cases yes, but check bore diameter and mounting details on your stock part. Measure and compare before fitting to ensure correct alignment and fitment.

Will the Aium 7075 finish require special care?

Routine cleaning after dusty runs and inspection for nicks is usually sufficient. The alloy is robust, but avoid abrasive cleaners that could affect the surface finish.

Does the pulley affect gearing or top speed?

Tooth count and diameter define gearing, so swapping to the AM-920041 maintains the intended 21T ratio. Performance changes are mainly in drivetrain feel and efficiency rather than gear ratio.
