Service Screw for S400/S411

The Serpent 401079 differential screw is a replacement part for S400/S411 1/10 190mm EP chassis, designed to retain correct differential alignment and reduce unwanted movement. It is intended for hobbyists focused on dependable drivetrain performance.

Steady Performance on Track or Trail

Compatible with the S400/S411 drivetrain layout, this screw helps maintain gear engagement and resist loosening during use. That makes it suitable for both competitive setups and casual bashing where reliability matters.

Quick Fitment for Routine Repairs

The screw fits into the Serpent S400/S411 chassis without modification, allowing fast swaps during maintenance or repairs. Replace the screw if you notice thread wear or persistent looseness after correct fitting.

Is this a direct replacement for the original screw?

This part is intended as a replacement for the S400/S411 series. Confirm the Serpent 401079 reference against your parts list before ordering to ensure a direct swap.

Will it help prevent differential binding?

A properly fitted, precision screw reduces slop that can contribute to binding, but binding can also come from gear mesh, bearings, or worn internals. Check those items if binding persists.

What should I check during a service?

Inspect the screw threads and seating face, check adjacent gears and bearings for wear, and confirm the screw is torqued correctly without over-tightening.
