Am interested in these hubs for my 2014 Ram 2500. Read the warning about the wheel center cap. My stock wheel caps are 4'' dia. but there is a ridge just inside the wheel for the cap to attach to. Have people been grinding that ridge down to the 4" dia.? That ridge looks "secondary" as far as strength to the wheel goes. But would this grinding not be advisable. Thanks. 2014 Ram 2500, 6.7, 4x4.
