KONI EVO Front Shock for 2022-Current Freightliner XC with VFS I-Beam Front Suspension Class A Motorhome (Part # 9905-1035)

Upgrade the ride quality and suspension performance of your motorhome with the KONI 9905-1035 EVO Front Shock, engineered for the 2022-Current Freightliner XC chassis equipped with VFS Four-Bar Linkage I-Beam front suspension. These premium shocks feature KONI EVO FSD technology, delivering improved ride comfort while maintaining superior chassis control for modern Class A motorhomes.

KONI EVO shocks incorporate 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 results in a ride that is comfortable on rough pavement yet stable 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 handle higher loads while operating at lower internal pressure. This improves cooling, responsiveness, and overall durability while delivering excellent suspension control.

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

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