Restore proper front-end ride height and handling with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4140, a complete front corner unit that arrives pre-assembled with the strut, mount and spring. It installs as a direct-fit replacement for the front of the 2003-2011 Ford Crown Victoria, 2003-2011 Lincoln Town Car, and 2003-2011 Mercury Grand Marquis. A front strut assembly supports vehicle weight, sets ride height, serves as the steering pivot, and contributes to overall stability, so worn units can show up as poor ride, bottoming out, or handling that feels loose.
Assembled in the USA.
