Upgrade SRX4 Belt Drive with Serpent 500446

For hobbyists pushing their SRX4 setups, the Serpent 500446 topshaft pulley is a small but vital part. It keeps belt engagement precise so torque moves through the drivetrain smoothly.

Why the 24-Tooth Choice Works

The 24T arrangement helps maintain steady torque transfer and cuts the risk of slippage under acceleration, making it suited to fast track layouts and spirited club runs. The pulley integrates cleanly with SRX4 components for quick installation.

Practical Fitment Notes

When fitting the pulley, check that belt alignment and tension are correct to avoid uneven wear. Routine checks after running sessions will help preserve drivetrain performance.

Can I use this with carbon fibre top decks?

Yes, the pulley works with standard SRX4 top deck configurations including carbon fibre, provided the belt path and mounts match stock geometry.

Does the pulley need lubrication?

The pulley teeth do not require lubrication, but keeping surrounding bearings and shafts lightly greased helps overall drivetrain smoothness.

Will it affect gearing ratios?

The pulley preserves the SRX4 gearing profile; swapping tooth counts will change ratios but the 24T is intended to balance torque and top speed for typical setups.

How often should I inspect the pulley?

Inspect the pulley after heavy sessions or exposure to dirt. A quick visual and hand-rotation check every few outings is a good habit.
