Tune Your S400 Drive with the 35T Pulley

Designed for S400 1/10 190mm EP chassis, the Serpent 401075 Differential Pulley & Shim 35T helps maintain correct gear mesh and steady drivetrain behaviour. It is a compact upgrade for hobbyists wanting more consistent power delivery.

Built for Consistent Gear Contact

The 35T pulley lowers friction and helps prevent premature wear on mating gears. The shims included let you micro-adjust the mesh so the pinion and pulley meet cleanly under load.

Quick Fit and Serviceable Design

The kit matches S400 mounting points for a straightforward swap, making mid-week maintenance or race-day repairs fast and reliable without extra modifications.

Practical Track Benefits

  • Precision Fit: Tailored to the S400 geometry for correct engagement.
  • Durability: Materials chosen to withstand repeated use.
  • Performance Boost: Smooths drivetrain losses for more linear throttle response.

Can I use this pulley with non-Serpent spares?

Compatibility depends on the other part dimensions. The set is made for S400 specs, so mixing with non-Serpent parts may require checking shaft diameters and spacing first.

How often should I check the shim setting?

Inspect gear mesh after a few runs and during routine servicing. Check for play and uneven wear and adjust shims if you notice noise or rough engagement.

Will the pulley affect drivetrain balance?

When installed correctly the pulley restores intended geometry and does not upset balance. Proper shim adjustment is key to avoiding vibration or uneven loading.

Is this product suitable for club racing?

Yes, it is aimed at hobbyists and racers who want tighter drivetrain behaviour. It is a practical upgrade for club-level competition where reliable gear mesh matters.
