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
