i have a lariat and want to replace my center caps with the fx4 ones has anyone tried this yet????????????????

 

They may not fit, not sure. I have a set of XLT wheels for my winter tires and the FX4 wheels for the summer. The center hubs are different sizes.

 

Those would be 17 and 18 inch wheels though. The Lariat and some of the FX4 have 18 inch wheels. I ordered mine with 18in wheels.

 

I agree that he would be going 18" to 18", but they are different style of wheels. The FX4 has cast aluminum, and the Lariat has polished aluminum. They may even come from a different manufacturer. They best way to check is go to the dealer and ask if he can try a FX4 hub on his Lariat.
