We picked these steel 5.7-inch H-beam connecting rods from Manley Performance because they can handle up to 700 hp and 8,000 rpm without issue. They are made from forged 4340 steel alloy and weigh just 665 grams each. We liked that these rods feature a compact uniform-grain structure for ultimate strength plus stress relieving and Magnafluxing to ensure consistent quality.
