NOTES: Read All Instructions Before Beginning Installation

  • Installation of a SPORTLINE Spring set should only be performed by a qualified mechanic experienced in the installation and removal of suspension springs.
  • Use of a hoist is highly recommended and will substantially reduce installation time.
  • Never work on or under a vehicle unless it is properly supported by safety stands and wheels are blocked.
  • SPORTLINE Springs are marked with the letter F and R (located at the end of the part number) designating front and rear springs.
  • SPORTLINE Springs should be installed with the Eibach Logo right side up. All original stock spring isolators, dampers and tubing should be retained from the stock springs and used when installing the SPORTLINE Springs.
  • After installation, it is always important to inspect and adjust the following if necessary:
    • Wheel alignment such as camber, caster & toe
    • Tire and/or wheel fender clearance
    • Brake line clearance and attachments
    • Brake anti-locking and anti-skid system sensors
  • Tire Rotation: In order to increase the life of your tires, it is recommended to rotate your tires every 3,000 miles.

ALIGNMENT:

After installation, it will be necessary to perform a full vehicle alignment using factory specifications.
