Heavy-Duty Front Shock Upgrade – KONI EVO for Country Coach & Freightliner w/ Neway IFS
Upgrade the ride and suspension performance of your diesel motorhome with the KONI 99B-3254 EVO Front Shock, designed for a variety of Country Coach, Freightliner, Spartan, Safari, and Foretravel Class A motorhome chassis equipped with either Neway Independent Front Suspension (IFS) or heavy-duty I-Beam front axles.
The KONI EVO 99 Series shock absorbers are engineered specifically for large motorhomes that demand superior ride comfort and durability. Featuring patented open intake valve technology, these shocks deliver a smooth ride over expansion joints and rough roads while still providing strong damping control to reduce excessive bounce and body movement.
The EVO 99 design utilizes a large 50mm piston, nearly 40% larger than the 36mm piston used in earlier KONI FSD shocks. The larger piston allows the shock to manage greater suspension forces while operating at lower internal pressure, improving both ride quality and long-term durability.
Originally developed for high-end European motorcoaches, the EVO 99 series is now being introduced into the North American RV market to deliver improved ride comfort, enhanced suspension control, and greater reliability for large diesel pusher motorhomes.
If your coach experiences front-end bounce, poor ride control, or worn-out factory shocks, upgrading to the KONI 99B-3254 EVO shock can significantly improve driving stability, ride comfort, and suspension performance.
