To order: Eibach Pro-Kit Lowering Springs 15 Challenger SRT, Hellcat
Eibach PRO-KIT is the perfect answer for most frequently-driven street cars. It's our legendary spring system that dramatically improves both a vehicle's performance and appearance.
PRO-KIT lowers your Hellcat's center of gravity, reducing squat during acceleration, body roll in corners and excessive nose-dive under braking. When combined with Plus-1 or Plus-2 wheels and tires, the Eibach PRO-KIT is the finishing touch to a winning recipe for performance. PRO-KIT also reduces excessive fender-well clearance, making your car look just as hot as it performs.
Every Eibach PRO-KIT is designed and tested by our suspension engineers and performance driving professionals, to deliver aggressive good looks and high performance handling, without ever compromising safety or ride quality. By using our proprietary, progressive spring design, PRO-KIT provides the ultimate balance to take your passion for driving to a whole new level.
