$274.99

Restore a firm, controlled ride with the KYB Strut-Plus complete strut and coil spring assembly (SR4078), a fully pre-assembled front corner unit that installs on the 2004-2008 Ford F-150 (2WD) and 2006-2008 Lincoln Mark LT. A strut assembly supports vehicle weight, sets ride height, serves as the steering pivot and helps control stability, and KYB engineers the Strut-Plus to help restore your vehicle's original handling and control.

Complete corner unit: includes a KYB Excel-G strut, the mount and an application-specific KYB coil spring, so these KYB complete struts drop in without separate spring compression or assembly.

Built to KYB spec: a stronger steel outer shell with application-specific, precision-designed damping valves, plus a high carbon steel coil spring developed around the vehicle's corner weights to help keep ride height within OE specifications.

Safety-system aware: engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.

Assembled in USA and pre-assembled for professional results.

Order this KYB front strut assembly as a direct-fit replacement for the applications above; see the Buyer's Guide tab to confirm engine and trim before ordering.
