Fine-Tune Your Drivetrain with Serpent 803185

The Serpent 803185 18T pulley shim helps bring tighter alignment to mid-centre drivetrain setups. Its compact 18-tooth form reduces unnecessary movement, helping models feel more responsive on track.

Made for Consistent Power Delivery

From Serpent, this pulley shim supports reliable gear engagement across compatible chassis. It pairs well with overdrive components to maintain smoother rotation at race pace.

Advantages for Track Use

Precision Fit: Minimises lateral play for steadier gear contact.
Durable Construction: Suited to frequent on-track stress and maintenance cycles.
Adaptable Use: Can be used across several mid-centre layouts when sizes align.

Do I need special tools to fit the shim?

Basic hobby tools are sufficient, though a feeler gauge and small driver can help you set precise spacing during installation.

Will this change gear ratios?

No, the shim does not alter tooth count; it adjusts spacing and alignment to improve how the existing gears engage.

How often should I check the shim after racing?

Check it during routine gearbox inspections and after any heavy impacts to ensure alignment is still correct and no movement has occurred.
