Balanced drivetrain upgrade for improved response

The Serpent 804301 Aluminum 40T Rear Gear Diff Pulley is machined to improve drivetrain response while cutting weight. Built from durable aluminum, this pulley balances strength and low mass to suit both club racers and weekend builders.

Lightweight design and long life

The anodized finish helps resist wear and corrosion for extended service life. Side cutouts lower rotating mass and allow trapped dirt to escape during runs, reducing debris buildup that can hinder drivetrain efficiency.

Wide fitment and typical uses

Made to work with a variety of RC setups, this 40T pulley is a handy upgrade for track racing or routine maintenance. It is suited to experienced competitors and hobbyists looking to refine drivetrain behaviour.

Will this pulley fit non-Serpent cars?

It can fit many models that share the same diff gear dimensions, but you should verify tooth count and mounting style before fitting to a different chassis.

How often should I clean the pulley after a run?

Inspect the pulley after each outdoor session and remove loose grit with a soft brush; the side holes help eject debris but routine cleaning prevents wear.

Do I need special tools to install it?

Basic hand tools and your model's service manual are usually sufficient for installation; if you are unsure, follow the chassis instructions or consult an experienced builder.
