Hello Ray, we have the Koni" FSD "shocks for that as well as the new Koni " EVO" series shocks .
They are :
8805-1020 - FRONT Freightliner XC I-Beam '93-Current (Koni FSD)
8805-1022 - REAR Freightliner XC (Koni FSD) Koni Frequency Selective Damping (FSD) shock absorbers provide superior handling characteristics without compromising ride comfort. The FSD is firm where you need it, such as through corners, but rides soft over expansion joints and rough roads. A special valve filters out annoying vibrations before they enter the vehicle, resulting in a smooth ride over a variety of road surfaces. or :
9905-1030 - FRONT Freightliner XC I-Beam '93-Current (Koni EVO)
9905-1031 - REAR Freightliner XC (Koni EVO) The EVO series is Koni's latest shock design. The main difference between the FSD and the EVO series piston is that it is almost 40% larger than the FSD series (50 mm vs 36 mm). The larger size means that it can take a lot more force, or the same force with less pressure which helps with cooling and better responsiveness. The larger body diameter allows for more oil capacity which also helps with cooling and increases the longevity of the shock. EVO series has a higher tensile strength than previous Koni designs. EVO incorporates open intake valves + FSD technology which exceeds the performance of FSD technology alone
