9905-1037 - FRONT Freightliner S2RV Super-C '18-Current (Koni EVO FSD)

Upgrade the suspension performance of your Super-C motorhome with the KONI 9905-1037 EVO Front Shock, engineered for the 2018-Current Freightliner S2RV Super-C chassis. These premium shocks feature KONI EVO technology, delivering improved ride comfort, superior suspension control, and long-term durability for heavy motorhome applications.

KONI EVO shocks utilize patented open intake valve technology that allows the suspension to absorb small road imperfections smoothly while still providing strong damping force during larger suspension movements. This creates a ride that is comfortable on rough pavement while maintaining excellent control during braking, cornering, and highway driving.

The EVO series features a large 50mm piston, nearly 40% larger than the piston used in standard FSD shocks (36mm). The larger piston allows the shock to manage greater suspension forces while operating at lower internal pressure, improving cooling, responsiveness, and overall durability.

With increased oil capacity, stronger internal components, and advanced digressive valve technology, the EVO series provides better body control, smoother ride characteristics, and longer service life for heavy Super-C motorhome chassis.

If your motorhome experiences front-end bounce, harsh ride characteristics, or poor suspension control, upgrading to KONI EVO shocks can significantly improve ride comfort, handling stability, and driver confidence.
