Drag Launch Spring Kits
    EIBACH Drag Launch Spring Kit

    The Eibach drag launch spring kit is specially engineered spring set designed to improve 60-foot times and off-the-line traction at the drag strip.

    During testing we have improved 60 foot times by 2 to 4/10ths of a sec. Drag Launch Spring Kits help reduce axle torque reaction through the use of carefully matched linear and progressive rear springs. Progressive rate front springs greatly improve load transfer to the drive wheels during acceleration.

    Eibach Pro-System = Pro-Kit Sport Springs + Pro Damper Sport Shocks

    Once you’ve decided you want sport springs, the Eibach Pro-System is the next logical step in achieving additional suspension performance. The Pro-System kits are designed by Eibach’s team of suspension engineers and ride control experts to offer great street performance without sacrificing much ride quality. The Pro-System is a combination of sport springs, matched dampers and bump stops tuned to operate as the foundation of your vehicle’s high performance suspension system.

    With the Eibach Pro-System installed, the vehicle is lowered (typically around 1-1/2 inches) as you improve the vehicle’s turn-in response, reduce its understeer and experience more ride control without sacrificing much ride quality.

    The Eibach Pro-Systems are precision engineered suspension systems that take away all of the guesswork. All you have to do is install…align…and enjoy.
