Precision Lightweight Drive Shaft for Viper 989

Improve your Viper 989's responsiveness with the Serpent 903810 Lightweight 2-Speed Shaft Set, engineered to cut rotating mass by 10 grams for crisper acceleration and handling. The 18-teeth pulley adapter is screwed to the shaft to provide a secure, low-play connection and consistent rotation.

Wear-Resistant Anodized Surface

The hard anodized aluminium finish offers reduced surface wear and reliable performance across repeated race sessions. Serpent's factory evaluations demonstrate the part's suitability for competition use.

Fitting Hints

Secure the pulley adapter using a 10mm open-ended spanner and a 3mm Allen key, tightening evenly to avoid misalignment. Correct assembly keeps the drivetrain smooth and reduces the chance of vibration-related issues.
