On all Manley connecting rods, 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.
300M
Like the Manley "
Turbo Tuff" series, Manley 300M connecting rods utilize all of the same machining processes and are held to the same high standards but are made from 300M alloy. Cap fasteners are 3/8" ARP 2000 cap screws. Optional 625+ upgrade available.
