Why Koni EVO?
The Koni EVO FSD 9905-1030 sets the benchmark for RV suspension with its unmatched blend of comfort, control, and longevity. Here’s why it’s the top pick for Freightliner XC owners:
- Superior Ride Comfort: Patented open intake valves and a 50mm bore piston (40% larger than standard FSD models) minimize internal pressure, delivering a smooth, vibration-free ride over rough roads, expansion joints, and bridges.
- Enhanced Handling and Stability: Custom-tuned valve stack and large piston holes provide precise body control, reducing pitching and swaying for confident handling during cornering, braking, and high-wind conditions.
- Advanced EVO 99 Technology: Built with 9-ton tensile strength and increased oil capacity, these shocks offer improved cooling and responsiveness, extending the lifespan of your RV’s suspension and tires.
- Designed for Freightliner XC: Tailored specifically for Freightliner air ride chassis with I-Beam front suspension, ensuring a perfect fit and optimal performance.
- Proven Durability: Constructed with premium materials and advanced valve engineering, these shocks withstand the toughest RV travel conditions, reducing maintenance costs and enhancing reliability.
- Outperforms Competitors: Unlike standard shocks, the Koni EVO FSD dynamically adjusts to road conditions, offering firm damping for control on rough terrain and soft damping for comfort on smooth roads, surpassing brands like Bilstein or Sachs.
This shock absorber’s ability to adapt to varying road conditions makes it the ultimate choice for RV owners seeking a smoother, safer, and more controlled driving experience.
