Caterpillar Connecting Rods Built for Heavy-Duty Reliability
Connecting rods are subject to tremendous stress from the reciprocating load represented by the piston, having to stretch and relax with every rotation. Failure of a connecting rod is one of the most common causes of catastrophic engine failure. This is why our Connecting Rods are made from steel forgings (malleable, spheroid-graphite iron casting or sinter forgings are beginning to be used for smaller engines).
Caterpillar connecting rods are the essential bridge between your engine’s pistons and crankshaft, converting the up-and-down motion of the pistons into the rotational force that powers your machine. Each CAT connecting rod is engineered for specific engine models ensuring precise fit, optimal balance, and reliable operation under the toughest conditions. Made from high-grade alloy steel and built to withstand the extreme forces and speeds of heavy-duty work, these rods are central to engine durability, efficiency, and long-term performance.
Available for a wide range of Caterpillar engines including the 3306, 3406, 3408, C9, C12, and more, each connecting rod is designed with the correct dimensions, bolt holes, and bearing surfaces for seamless assembly and dependable function. Regular inspection and replacement of worn or damaged connecting rods help prevent catastrophic engine failure, reduce vibration, and extend the life of your equipment.
Propel Parts offers a comprehensive selection of high quality replacement connecting rods for Caterpillar equipment, with clear compatibility and easy online ordering. Fast shipping and expert support help you quickly find the right part, so you can keep your engine running smoothly and avoid costly downtime.
