Refine Drivetrain Efficiency with Serpent 803185

The Serpent 803185 pulley shim is made to fine-tune the drivetrain on mid-center RC layouts. This 18-tooth shim helps align gears and reduce unwanted drag so models run smoother under load.

Built for Accurate Alignment

From Serpent, a brand known for thoughtful RC parts, this 18T shim supports precise gear positioning across a range of chassis. It works well when paired with overdrive conversion kits, helping maintain consistent behaviour at speed.

Practical Advantages

Precision Fit: Keeps gear spacing accurate to lower friction and wear.
Durable Construction: Designed to take the stresses of racing and regular track use.
Flexible Application: Suitable for different mid-center drivetrain configurations.

Will this shim work with a 720 overdrive conversion?

It is commonly used alongside 720-style overdrive kits when the pulley dimensions match; check gear spacing and shaft offsets before fitting.

How should I set gear mesh after installing the shim?

Start with a conservative mesh, then run the drivetrain at low speed to spot any binding. Fine-tune by small adjustments until noise and slop are minimised.

Does the shim need regular maintenance?

Inspect it during routine drivetrain checks for unusual wear or movement, and recheck alignment after crashes or gearbox servicing.
