MIA's Description

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. These rods are weight matched to +/- 1.5 grams, feature perfectly round big and small ends, and tightly controlled bend and twist. Cap fasteners are 3/8" ARP 2000 for the "H" Beam rods.
