Construction & Design

The KONI STR.T dampers feature a twin-tube design with adjustable rebound settings, allowing drivers to fine-tune suspension stiffness to their preference. The dampers are finished in KONI’s distinctive orange powder coat, providing corrosion resistance and a professional appearance under the vehicle. Paired with Eibach’s high-quality lowering springs, crafted from progressive-rate steel alloys, this kit ensures consistent performance and longevity.

Engineered to work in harmony, the springs and dampers maintain the Chrysler 300’s suspension geometry and alignment specifications, preserving tire wear characteristics and steering precision. The lowering springs reduce the center of gravity, which contributes to improved handling dynamics without compromising ride smoothness.

Installation & Fitment

This suspension kit is designed for straightforward installation on Chrysler 300 models from 2005 through 2010. The components are direct replacements for the factory shocks and springs, requiring no cutting, welding, or additional modifications. Installation can typically be completed with standard suspension tools and a moderate level of mechanical experience.

For optimal results, it is recommended to have a professional alignment performed after installation to ensure proper handling and tire wear. The kit is compatible with stock wheels and tires, though wheel clearance should be verified if aftermarket wheels are installed.
