Installed these on my 14 F150. It would have been an easy install, but removing one of the factory fenders resulted in a bolt popping out that should have been welded to the frame, making for an interesting install. This isn't Timbrens' fault, though. The timbres were easy to install and they feel great on the road. With my slide in the camper there is almost no role. The only problem is that by being in constant contact with the axle, all vibrations and shocks are transmitted through it.
