Dial In Drivetrain Response with the Serpent 401077

The Serpent 401077 35T one-way pulley is built to improve drivetrain efficiency and give better control for S400 and S411 1/10 setups. It helps keep power delivery smooth at speed and reduces drivetrain losses on the race line.

Precision Machining for Track-Level Control

Made with tight tolerances, this 35T pulley refines power transfer for consistent engagement. The one-way mechanism cuts back on backlash during acceleration, providing firmer traction across asphalt and prepared surfaces.

Fitment and Simple Installation

Designed as a direct replacement for the S400 1/10 190mm EP chassis, the Serpent 401077 installs without major modifications. Basic tools and routine checks will get you back on track quickly after fitting.

Key Improvements for Race Setups

  • Improves drivetrain efficiency and control
  • Compatible with S400/S411 series
  • Easy to install as a direct replacement part
  • Enhances traction and reduces slippage

Will this pulley fit older S-series cars or only S400 and S411?

The Serpent 401077 is optimised for the S400 and S411 platforms. If you want to fit it to other models, measure shaft diameter and clearance before attempting installation.

How does the one-way design change handling during acceleration?

The one-way mechanism improves forward drive engagement and reduces coast-related slop, which gives a cleaner throttle response and better traction on acceleration.

What maintenance should I perform after fitting the pulley?

Check fastener torque, inspect the pulley for wear, and keep adjacent bearings clean. Periodic inspection prevents unexpected drivetrain issues.
