Progress Tech 04-10 Dodge Chrysler 300C/2009+ Dodge Challenger V8 Sport Springs

This kit includes a set of four Progress Tech sport-lowering springs designed to give your Dodge Challenger a more aggressive stance and better handling. You get two front springs and two rear springs, all made from certified high-tensile SAE spring wire. They are cold-wound on CNC machines, then stress-relieved, pre-set, and shot-peened for maximum durability before receiving a protective powder coat finish.

These springs will lower the front of your Challenger by about 1.6 inches and the rear by about 1.4 inches. This not only improves the vehicle's appearance by reducing fender gap but also lowers the center of gravity, which helps reduce body roll during cornering. The sport-tuned spring rates, 310 lb/in in the front and 725 lb/in in the rear, are designed to work with your factory shocks, though they pair well with performance dampers like Bilstein or Koni for an even sportier ride quality.
