The Eibach Drag Launch Kit Springs optimize Dodge Challenger SRT Hellcat for drag racing. Crafted from high-tensile steel, these springs lower the vehicle slightly to reduce weight transfer, enhancing traction and launch control. Designed for Hellcat coupes, the four-piece set ensures consistent 60-foot times, ideal for track use. Installation requires compatible shocks and alignment. Powder-coated for durability, it includes a limited lifetime manufacturer warranty.
