Manley steel H-beam connecting rods are made from forged 4340 steel alloy. They’re packed full of performance features, such as a compact uniform-grain structure for ultimate strength, full machining, stress relieving, and magnafluxing. The wrist pin and big end bores are honed to a +/-.0002 in. tolerance, and the wrist pins get a bronze alloy bushing. These units include cap screw ARP 8740 alloy rod bolts, and each rod set is weight-matched to within 2 grams.
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.
