Optimise Gear Alignment with Serpent 803185

The Serpent 803185 18T pulley shim is aimed at tightening gear alignment on mid-centre drivetrains. This shim helps the drivetrain run with less resistance, improving consistency over longer runs.

Precision That Helps Handling

Made by Serpent, the 18T shim supports steady engagement across suitable chassis types. It complements overdrive conversion kits by helping maintain smooth gear motion at speed.

Why Fit This Shim?

Precision Fit: Keeps gear faces properly aligned to reduce noise and wear.
Durable Construction: Built to handle regular use and demanding track sessions.
Multiple Uses: Useful across different mid-centre drivetrains where dimensions match.

Is the shim compatible with my existing overdrive kit?

Compatibility depends on pulley diameter and shaft offset; confirm measurements against your kit before fitting to ensure correct pairing.

Will fitting the shim require gearbox rework?

In most cases it is a simple swap or add-on, but some gearboxes may need minor spacing adjustments to achieve ideal mesh.

What checks should I do after installation?

Run the drivetrain slowly to listen for binding, then test at full power. Reinspect after a short session to confirm no loosening or unusual wear.
