What is FSD technology?

FSD stands for Frequency Selective Damping. This technology allows the shock absorber to automatically adjust its damping characteristics based on road conditions. It provides a softer ride at low speeds and firmer damping for better control during faster driving or cornering.

Will these shocks make my RV handle better?

Yes, these Koni shocks are designed to improve your RV's handling by reducing body roll and increasing stability. The advanced valving helps keep the vehicle more planted, especially on uneven roads or in windy conditions, leading to a more confident driving experience.

Are these shocks difficult to install?

These shocks are designed as a direct replacement for your original equipment. While installation difficulty can vary, they typically bolt on without requiring specialized tools or modifications, making it a manageable job for many RV owners.
