The Manley H-Beam Series Connecting Rods are not only very ''economically'' priced, but they are finished to the same exacting tolerances and high quality standards as their Sportsmaster and Pro Series rods. Final hone size, thread detail, bend and twist - these are attributes we take very seriously. You will find the Manley H-Beam rods superior to others on the market.
