No, these are longer. I don't know by how much, but they are the ones to use for most brake swaps. I have them on the front for 8mm thicker rotors (Grand Am swap) and on the rear for 8mm spacers. The studs protrude through the stock lug nuts on both ends.
Stock (Dorman 610-254) is 41.5 mm, Dorman 610-323 is 54 mm
Edited to add stud info.
