The rotors are made in canada, the calipers are 81-87 GM fullsize truck calipers for more ready availibility, the hoses are longer than OEM and differ from 71-72 so that you can use original hard lines and not have to swap to 71-72 steel brake lines, the bearings are 71-87 Chevy & GMC 1/2 ton inner and outer bearings and seals again for easy availibility. Dust shields are not included but we do offer them, as dust shields are actually a matter of taste as disc brakes are self cleaning and many modern vehicles no longer use the shields on the inside and with todays modern wheels rotors see no more protection on the face than they do on the back side.
