Product Summary

03-11 Ford Crown Victoria, Front Position, Anodized

  • These QA1 Crown Victoria Pro Coil Systems are a great option for anyone looking for fully adjustable ride height and valving control
  • Choose a spring rate and adjustability that fits your driving style (sold as separate part numbers), adjust the valving to match, and you are on your way
  • These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling
  • Specially designed for QA1's Pro Coil Systems, the American-made lightweight high travel springs have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils
  • They reduce unsprung weight and react faster, optimizing suspension performance
