Track-Grade 42T Spur for S240

The Serpent 421020 42T spur gear is built to match the S240 Electric Pancar drivetrain, delivering accurate engagement and consistent service life under race conditions. As a core drivetrain part, this spur is made to fit cleanly and help maintain drivetrain efficiency between events.

Optimize Your Drivetrain

With a rugged design this 42T spur handles the stresses of competitive laps while preserving smooth power transfer. It installs easily in S240 setups and is a practical choice when replacing worn gears or prepping a car for the upcoming race weekend.

Will this fit other Serpent pan car models?

This 42T part is specifically designed for the S240 Electric Pancar lineup. For other Serpent models verify tooth count and mounting details against the vehicle specifications.

How should I inspect the gear after racing?

Check for chipped or worn teeth, ensure the bore is round, and confirm there is no excessive play on the shaft. Clean debris and inspect mesh with the pinion before reinstalling.

Any tips for installing the spur in my S240?

Fit the spur squarely on the shaft, align pinion mesh per factory guidelines, and tighten fasteners to spec. Spin the drivetrain by hand to confirm smooth engagement before running.
