Performance Handling. SR Performance's Lowering Springs are an excellent way to improve the handling performance of your Charger. These Springs will lower your Charger's center of gravity, which will reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. SR Performance Springs are perfectly suited for daily driving, street, and occasional track applications.Aggressive Muscle Car Stance. Not only does a set of SR Performance Springs improve the handling performance of your Charger, but they also improve its overall appearance by lowering the ride height approximately 2.0-inches front and 2.1-inches rear eliminating that huge tire to fender gap, for a more aggressive street stance.Progressive Design. Progressive springs (also known as variable rate springs) are designed to be more compliant when riding over rough and uneven surfaces like public roads. Progressive springs are engineered with a low starting spring rate that increases as the spring compresses. Variable rate compression allows for a smoother ride, while still providing good handling characteristics when pushed hard. This makes progressive rate springs a popular choice for daily street driven Chargers.Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your factory size wheels and tires, as well as AmericanMuscle's pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.Professional Installation Recommended. Seeing that a spring compressor is required for installation of these Coil Springs, AmericanMuscle recommends professional installation. With the proper tools, installation can be completed in about three hours. Please note that an alignment is highly recommended after installation.Application. This set of four SR Performance Lowering Springs are specifically designed for use on 2006-2023 RWD Chargers equipped with independent rear suspension (IRS). Does not fit SRT models.
