Manley Performance manufactures the finest steel connecting rods in the Sport Compact industry. Manley's H-Beam rods are manufactured from 4340 alloy forgings. They are fully machined, heat treated, stress relieved, shot peened, and magnafluxed. They also are built standard with 3/8" ARP 2000 bolts.
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.
Engine assembly should be done by a professional.
