Brackets are 304 stainless which is nice, however tyhe bolts are not and should be. The welded nuts on the brackets had weld overflow, needed to retap threads, should have been checked prior to shipping. Other than that like that they mount to body frame bolts and not to rocker panel. Look great after install.
