These spark plugs are the same as the Autolite XP985 except they have a cooler spark plug area than the XP985. They fit the 4.0 I6 with no difference in size. Replacing XP985 with XP5405 solved my problem with ping after ring. The plugs were not offset to a specific value and had to be adjusted to 0.035.
