The Koni Gold FSD (now red in color) rear shocks for your Sprinter 3500 2wd van or cab chassis have Frequency Selective Dampening. This is the shock that will adjust according to road conditions and driving habits, without electronics. An excellent upgrade to the factory shock. Great for RV's that carry passengers in the rear. No need to make manual adjustments; the FSD's specially designed valve will adjust quickly to help you have better control under harsh road conditions, yet maintaining a soft easy ride under smooth conditions.
