The Hotchkis Sport Suspension Stage 1 TVS system for the 2011 Dodge Challenger RT offers a sleek lowered stance, dramatically improved handling and superior driver control. Our engineers poured over track testing data to develop a balanced handling system, comfortable enough for the street, but well balanced for the occasional track day or your favorite twisty road. The system is comprised of lowered, higher rate sport coil springs paired with front and rear, lightweight sway bars and rear Bilstein shocks. All components are manufactured in the USA, come with complete hardware, greasable bushings and are finished off in a durable powder coated finish. This bolt on upgrade can transform your Challenger into a canyon carver in minutes.
