Product Description

The KONI 9905-1037 EVO FSD Front Shock Absorber is engineered specifically for the front suspension of **2018-2025 Freightliner S2RV and Super-C Class A motorhome chassis**. Featuring KONI's advanced EVO99 technology combined with Frequency Selective Damping, this shock delivers a remarkable balance of comfort and control. The patented open-intake valve and increased 50 mm piston bore allow adaptive damping - soft over minor surface imperfections yet firm when cornering or braking hard - making long highway travel and heavy loads more confident and comfortable.

Constructed with heavy-duty materials designed for the demands of large RV travel, the 9905-1037 maintains OEM mounting points with direct bolt-on fitment (eyelet upper and lower). Its enhanced design ensures increased oil capacity, better thermal control, and reduced body motion compared to standard FSD models. Whether cruising interstate or navigating campsite roads, this shock improves front suspension performance, stability, and passenger comfort. Shocks are sold individually - order two for a complete front suspension set.
