This version of the Bilstein 5100s do fit 4WD F150s and are more than adequate for street trucks or F150s that see light-duty off-roading. The kit replaces your F150s front struts and rear shocks and is suitable for F150's at factory ride height. This kit is specific for 4WD F150s. If you have an RWD truck, then you'll need our 5100 Series Kit for RWD F150s.
