Replacement for S400/S411 Differential

The Serpent 401079 Differential Screw is a service item for S400/S411 1/10 190mm EP models, helping to maintain correct diff assembly and minimise wear. Its accurate fit aids dependable operation between services.

Durability and Driveability

Designed to match the S400/S411 drivetrain, the screw gives a stable mounting point that supports predictable handling and consistent gear engagement during both technical sections and fast straights.

Installation Notes

Fitting into the Serpent S400/S411 chassis is straightforward; ensure mating parts are clean and the screw is tightened to an appropriate level to avoid stripping threads. Include it in regular maintenance intervals to keep the drivetrain reliable.

Will this fit older versions of the S400 chassis?

The screw is specified for the S400/S411 range. To confirm compatibility with earlier variants, compare the Serpent 401079 reference to the service parts list or check the part dimensions.

Can this affect my diff tuning?

The screw secures the diff assembly which helps hold your tuning settings steady. Final tuning is achieved through the diff internals, shims and oils rather than by this fixing alone.

How do I know when to replace it?

Replace the screw if threads are damaged, it fails to seat correctly, or if it repeatedly loosens when fitted properly. Regular inspection during services will reveal these signs early.
