Let me guess, your doors rattle, right? Its a relatively known issue on all of the 1999-2016 SuperDuty trucks. Have you ever noticed that the F-150's doors DON'T rattle? That's because their door striker has a rubber stopper pad that eliminates the metal-on-metal contact that causes the bigger trucks' doors to rattle. The good news is you can quite literally use the F-150's striker on the other trucks for a direct bolt-on upgrade. These are sold individually and will work on Regular Cabs, Crew Cabs, and Excurion models, but will NOT fit Super Cabs.
