Description

Connecting rods are fully machined from a proprietary 4330m alloy forging, ensuring exceptional strength and durability. They are available with two bolt options: the standard WMC-H7 (H11) bolt, offering a UTS of 220 ksi, and the upgraded CARR-S7 (MP35N) bolt, with a UTS of 285 ksi. All bolts feature asymmetrical threads for evenly distributed thread engagement, enhancing clamp load and extending the fastener's fatigue life. For added durability, a Mahle steel bushing is included, with Cap Relief to assist in oil evacuation for engines running at higher loads and RPMs.
