4G63 / 4G64 - ECONOMICAL "H" BEAM STEEL CONNECTING RODS - learn more about our connecting rods

Manley "H" Beam connecting rods are manufactured from 4340 forgings to the same exacting standards developed and approved by our original equipment customers. There is a vast difference in quality between a Manley "H" Beam and the "other" inexpensive H-Beams on the market. Weight matched to +/- 1.5 grams. Perfectly round big and small ends. Bend and twist is tightly controlled. Cap fasteners are 3/8" ARP 2000 for the H-Beam and H-Tuff and 3/8" ARP Custom Age 625+ for the H-Tuff Plus. H-Tuff and H-Tuff Plus Series have a heavier beam for higher boost applications.
