Construction & Design:

AST Lowering Springs are crafted from premium-grade spring steel, ensuring strength and durability under demanding driving conditions. The springs are cold-coiled on state-of-the-art Wafios coiling machines, which provide exceptional precision and consistency in coil dimensions and spring rates. This advanced manufacturing process results in springs that deliver predictable handling improvements while preserving ride quality.

The progressive design of the springs means the rate increases as the suspension compresses, allowing for a smooth initial ride and firm support during aggressive cornering or spirited driving. This thoughtful engineering approach ensures the springs perform well on both daily commutes and performance-oriented driving scenarios.

Installation of the AST Lowering Springs is straightforward, as they are designed to be a direct swap for the OEM springs on the Chrysler 300 Base (2005–2007) and LX (2008–2009) models. No additional modifications or special tools are typically required, making it an accessible upgrade for enthusiasts and professional installers alike. It is recommended to have a professional alignment performed after installation to ensure optimal handling and tire wear.

Note that these springs are not compatible with vehicles equipped with Hydractive III+ suspension systems, so verify your suspension type before purchase.
