Cummins Full Series Engine Connecting Rods
M11 Connecting Rods
Product Overview
Cummins M11 series connecting rods are core transmission components tailor-made for M11 full-electronic diesel engines, including Xi'an Cummins ISM11 and QSM11 models. As the critical link connecting pistons and crankshafts, the connecting rod converts the reciprocating motion of pistons into rotational motion of the crankshaft.The M11 engine is widely fitted on heavy-duty trucks such as Shaanxi Automobile Delong and Auman, as well as XCMG excavators and Sany rotary drilling rigs. Our connecting rods are forged from high-strength steel, featuring exceptional fatigue resistance and impact toughness. They withstand huge alternating loads generated by the engine’s high combustion pressure, ensuring stable and efficient power transmission.
