Product Description

The KONI 9905-1035 EVO FSD Front Shock Absorber is designed for rugged, heavy-duty performance on 2022 and 2025 Freightliner XC Class A motorhome chassis equipped with Hendrickson VTEK (VFS) I-Beam front suspension. Its advanced EVO FSD technology combines KONI's Frequency Selective Damping with a patented open-intake valve and a larger 50 mm piston bore, delivering a superior balance of comfort and control for RV owners who spend long hours on diverse road surfaces. These shocks help minimize front-end pitching and vibration, improving overall ride quality and driver confidence.

Heavy-duty construction and direct bolt-on installation make the 9905-1035 an ideal replacement or upgrade for stock front shocks on Freightliner XC RVs with VFS suspension. It's engineered to withstand the demands of large motorhome driving - from highway cruising and heavy loads to rough backroads - while maintaining stability under braking and in crosswinds. For best performance, replace shocks in pairs and verify that your motorhome uses a Hendrickson VTEK I-Beam front axle before installation.
