Main differences are stainless steel tie rods, reuses stock dust caps and stock steel sleeves, addition of zerk fittings, and matte black powder which is higher quality compared to old ones. Alba also says the geometry has been changed but i did not measure the motion ratio on old arms to compare. I do know the tie rods are longer. New arms use the same ball joints. I will post more pics in my build thread later. Sent from my iPhone using Tapatalk
