Chrysler 300 / 300C 05-12 5.7L Hemi

ASTLS-14-515

Overview:

The AST Lowering Springs are engineered to enhance the driving dynamics of your Chrysler 300 from 2005 to 2012 by lowering the vehicle’s center of gravity without sacrificing the ride comfort you expect from your original equipment manufacturer (OEM) springs. Designed as a direct replacement for your factory springs, these lowering springs provide a subtle yet effective drop that improves handling, reduces body roll, and sharpens cornering response. Ideal for enthusiasts seeking a balanced upgrade, the AST springs maintain daily drivability while delivering a sportier stance and improved road feel.

Crafted specifically for the Chrysler 300 lineup, including the 300 C, 300 C Luxury (2012), and 300 S (2010), these springs offer a tailored fitment that ensures optimal performance and reliability. Whether you’re looking to enhance your vehicle’s appearance or improve its handling characteristics, AST Lowering Springs provide a dependable and long-lasting solution.

Construction & Design:

AST Lowering Springs are manufactured from high-grade spring steel, ensuring strength and durability under demanding driving conditions. The springs are cold-coiled on advanced Wafios machines, which provide exceptional precision and consistency in coil geometry. This manufacturing process results in a progressive spring rate that gradually increases stiffness as the suspension compresses, allowing for a smooth transition from comfort to performance driving.

The design is vehicle-specific, meaning each spring is engineered to match the weight distribution and suspension characteristics of the Chrysler 300 models it fits. This tailored approach guarantees optimal ride height reduction without compromising suspension travel or causing premature wear on other components.

Installation of AST Lowering Springs is straightforward, as they are designed to be a direct swap for the OEM springs on Chrysler 300 models from 2005 through 2012. No special tools or modifications are required, making them suitable for professional installation or experienced DIY enthusiasts. Proper installation will restore factory suspension geometry while lowering the vehicle approximately 1 to 2 inches, depending on the model and axle.

These springs fit the following Chrysler 300 variants:

• Chrysler 300 C (2005–2012)
• Chrysler 300 C Luxury (2012)
