40.0635
Overview:
Progress Technology Sport Springs are engineered to enhance the appearance and handling of your Chrysler 300, Dodge Magnum, Charger, or Challenger. Designed for enthusiasts seeking a sportier stance and improved driving dynamics, these lowering springs reduce the vehicle’s center of gravity, resulting in sharper cornering and reduced body roll. The sport-tuned spring rates provide a balanced ride quality that is both engaging and comfortable for daily driving. Ideal for owners who want to upgrade their suspension without replacing OEM shocks, these springs deliver noticeable performance gains while maintaining reliability.
Key Features:
Progress Technology Sport Springs combine advanced engineering with high-quality materials to deliver superior performance and durability. Key features include:
- Front lowering height of approximately 1.6 inches and rear lowering height of 1.4 inches for an aggressive, lowered stance
- Sport-tuned spring rates: 310 lb/in front and 725 lb/in rear, optimized for improved handling and reduced body roll
- Designed to work seamlessly with OEM shocks, with enhanced benefits when paired with high-performance dampers such as Bilstein, Koni, or Tokico
- Manufactured using certified high-tensile SAE spring wire for strength and longevity
- Cold-wound on CNC coiling machines for precision and consistency
- Stress-relieved, pre-set, and shot-peened to maximize durability and fatigue resistance
- Finished with a durable powder coat for corrosion resistance and a sleek appearance
- Extensive fitment coverage across multiple Chrysler and Dodge models from 2005 through 2023
Construction & Design:
Each Progress Technology Sport Spring is crafted from premium high-tensile SAE spring wire, ensuring exceptional strength and resilience under demanding conditions. The springs are cold-wound on state-of-the-art CNC coiling machines, guaranteeing precise dimensions and uniform performance. Following coiling, the springs undergo a stress-relief process and are pre-set to maintain consistent ride height and handling characteristics. Shot-peening further enhances fatigue life by reducing surface imperfections. Finally, a robust powder-coated finish protects against corrosion and wear, ensuring long-lasting durability and an attractive look under the vehicle.
Installation & Fitment:
Progress Technology Sport Springs are designed for direct bolt-on installation with the factory suspension components on compatible Chrysler 300 (2005–2010), Dodge Magnum (2005–2008), Dodge Charger (2006–2010), and Dodge Challenger (2009–2023) models. No modifications to the chassis or suspension are required, making installation straightforward for professional shops or experienced enthusiasts. While these springs work well with OEM shocks, pairing them with upgraded dampers such as Bilstein, Koni, or Tokico will maximize handling improvements and ride quality.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
