Precision Spur Gear for Eryx 411 Tuning

The Serpent 120043 spur gear is intended for the Eryx 411 4.1 Touring Car EP and comes in a 48-pitch, 71-tooth format. Its design supports consistent torque transfer and clean tooth engagement to aid lap-to-lap consistency. Compatibility extends to S400 and S411 series gearboxes for flexible use.

Performance Reasons to Fit a 71T Spur

The 48P 71T choice provides a useful mix of torque and achievable top speed, helping drivers adjust their gearing for track grip and motor characteristics. It is a practical upgrade when restoring a worn spur or refining ratios.

Simple Fitment and Practical Advice

This spur fits the Serpent Eryx 411 4.1 and works with S400 and S411 families. Installation is quick for experienced hobbyists; set mesh using a feeler or shim and confirm all fasteners are secure before running.

Is this the same pitch used on stock kits?

Most Serpent touring kits use 48P spur gears; the 120043 follows that standard, but always compare with your existing gear to be sure.

Will a larger spur damage my motor?

A larger spur changes the load on your drivetrain and may affect motor RPM and current draw. Match spur and pinion choices with your motor and ESC settings to avoid overheating.

How often should I inspect the spur?

Check the spur for wear after each race day or practice session, and look for uneven wear patterns that could indicate a mesh problem.

Can I run this on carpet or asphalt?

Yes, the gear suits standard touring surfaces like carpet and asphalt; adjust gearing and tyres to suit grip levels on each surface.
