The Serpent 902139 servo saver spring in black is a targeted upgrade for RC drivers wanting crisper steering on high-grip surfaces. It offers firmer tension versus the stock silver spring to help you achieve more precise inputs during tight competition.
Built for high-traction conditions, the black spring increases resistance in the servo saver to sharpen steering feel on a Serpent 950 chassis. The firmer spring lets drivers make more exact corrections when cornering around demanding race circuits.
Installing the black spring is straightforward and keeps setup time to a minimum. It is a direct replacement for the Serpent 950 chassis and does not require additional modifications.
