High precision parts for classic racers

The Serpent 802171 aluminum pulley and shim set is made for the vintage 720-09 200mm GP series and delivers durable, low-mass components ideal for restoring or upgrading classic RC cars.

Lightweight aluminum for improved drivetrain response

Machined from aluminum, the 21T pulley and shim offer greater strength while cutting weight versus stock materials. That combination helps reduce rotating mass and can make the drivetrain feel smoother under load.

Simple fitment for 720-09 GP chassis

This set is matched to the Serpent 720-09 200mm GP layout and installs cleanly into the original configuration. It is a practical choice when refreshing ageing parts or enhancing reliability on the track.

Can I fit this pulley to other 200mm models?

The Serpent 802171 is sized for the 720-09 200mm GP chassis. Some other 200mm cars might accept it with minor modification, but exact fit is not guaranteed.

How should I maintain the pulley and shim?

Keep the pulley and shim free of grit and check for wear regularly. Clean with a soft brush and light solvent, then inspect mating surfaces and replace if you notice play or deformation.

What lubrication is recommended?

Use light bearing oil on any rotating bearings and avoid heavy grease on gear faces. Make sure lubricant does not contaminate belts or friction surfaces.
