Serpent 401020 Precision Differential Spring 1/10 Scale  [SER401020]

Dial In Your Setup with Serpent Differential Spring

The Serpent 401020 differential spring is a compact upgrade for 1/10 scale S400 and S411 chassis. Engineered to hold consistent preload, it helps stabilise differential behaviour so your car responds more predictably through high speed corners and under acceleration.

Fine Tuning for Race Setups

This spring lets racers alter how torque transfers across the diff to tweak traction and mid corner balance. Its steady response suits drivers who adjust settings for carpet or asphalt circuits and want repeatable handling changes.

Fitment and Durability

Made to suit the S400 and S411 series, this spring works as a direct replacement or spare part for regular maintenance. Durable construction resists fatigue so you keep consistent diff action over multiple race days.
