Reliable 20-Tooth Pinion for the Viper 988-e

The Serpent SER904175 Pinion 20T is a practical replacement part for maintaining consistent performance in Viper 988-e electric cars. Its 20-tooth design balances acceleration and torque for everyday track use.

Intended Fit and Performance

Specifically matched to the Viper 988-e layout, this pinion offers a direct fit in compatible drivetrains. It is suitable for drivers focused on predictable gear engagement rather than experimental setups.

Practical Installation Advice

Fit the pinion square to the motor shaft and set the mesh so there is a small, even gap under load. Recheck the alignment and fasteners after initial runs to avoid loosening and uneven wear.

Yes, replacing the pinion is a straightforward job for anyone comfortable with basic RC maintenance. Remove the motor if needed to access the shaft and use the correct Allen key for the grub screw.
Changing tooth count will affect acceleration and top speed but will not directly change steering. Select a ratio that suits your track and motor to keep handling consistent.
Look for rounded or chipped teeth, noisy engagement, or increased backlash. Replace the pinion if you notice these signs to protect the spur and motor.
