All Manley connecting rod sets are weight matched to 1.5 grams, big and small end bores are final honed to a tolerance of .0002", critical bend and twist attributes are held to a minimum, and exacting attention is paid to every detail by their final inspection department; thus rendering a finished product that is second to none.
