Serpent 902139 Black Servo Saver Spring Competition Fit  [SER902139]

Improve Steering Control with Serpent 902139

The Serpent 902139 black servo saver spring is a straightforward upgrade aimed at drivers using high-grip tracks. It supplies a firmer spring rate compared with the silver variant to improve steering precision during races.

Why the Black Spring Helps on Sticky Tracks

Engineered for traction-heavy conditions, the black spring increases resistance in the servo saver to provide steadier steering on the Serpent 950 chassis. That additional firmness helps convert subtle radio inputs into consistent steering action.

Compatibility and Easy Replacement

Fitting the black spring is a simple swap that keeps setup time low. The part is a direct replacement for the Serpent 950 and generally requires no extra parts or machining.
