Construction & Design:

AST Lowering Springs are crafted from premium-grade spring steel, cold-coiled on state-of-the-art Wafios machines to ensure precise dimensions and consistent spring rates. This manufacturing process enhances the springs’ strength and longevity while maintaining the flexibility needed for a comfortable ride. The progressive design means the springs become stiffer as they compress, providing a smooth initial ride with increased resistance during aggressive driving or cornering. This thoughtful engineering results in improved handling dynamics without harshness or excessive stiffness.

Installation & Fitment:

These lowering springs are designed as direct replacements for the OEM springs on Chrysler 300 models from 2005 through 2011, making installation straightforward with no need for additional modifications or special tools. Professional installation is recommended to ensure proper alignment and suspension setup after fitting. Note that these springs are not compatible with vehicles equipped with Hydractive III+ suspension systems.
