Don’t be fooled; not all H-Beams are created equal. Manley H-Beams are not only very “economically” priced, but they are finished to the same exacting tolerances and high-quality standards as our 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. Available with both ARP 8740 and ARP 2000 bolts.
