Strengthen Your Drivetrain with a 21T Pulley

The Serpent 804199 21T Aluminum Pulley is a precision component crafted to improve the behaviour of 2-speed transmissions. Made from durable aluminium, it helps keep gear engagement consistent while resisting the wear common in race use.

Durable Aluminium for Repeated Use

This hard-anodized 21T pulley is built for durability, maintaining its profile through heat and repeated loads. Precision cuts ensure accurate tooth alignment and smooth interaction with mating parts.

Optimised for Shift Control and Torque Delivery

Designed with 2-speed RC cars in mind, the pulley supports more efficient torque transfer and clearer shift points, assisting drivers who are dialing in acceleration and handling balance.

Can I use this pulley on both on-road and off-road cars?

It fits 2-speed transmissions regardless of surface, but verify fitment with your chassis and gearbox type before purchasing.

Will this reduce drivetrain backlash?

Tighter manufacturing tolerances help minimise play, which can reduce perceived backlash when the pulley is fitted correctly.

Any recommended lubricants during installation?

Use light assembly grease on bearings if applicable and avoid heavy oils on contact faces; check the car manual for any manufacturer recommendations.
