Serpent 902139 Black Servo Saver Spring Precision Fit  [SER902139]

Dial In Steering Response with Serpent 902139

The Serpent 902139 black servo saver spring is aimed at racers who run on high-traction surfaces and want a firmer steering feel. Compared with the standard silver spring, the black unit adds resistance to the servo saver for cleaner steering inputs.

Designed for Sticky Surfaces

When running on high-traction tracks, the increased stiffness of the black spring helps the Serpent 950 chassis keep a steadier front end. That extra resistance helps translate subtle radio inputs into predictable wheel movement.

Quick Installation and Compatibility Notes

Swapping to the black spring is a simple maintenance task with minimal downtime. It fits the Serpent 950 as a direct replacement and usually needs no additional parts or adjustments.
