PowerBore now manufactures steel connecting rods for most high performance tractor and truck applications. Our rods are machined from 4340 steel billet, and heat treated in house to achieve optimal mechanical properties for your performance engine.
Connecting rods serve as the intermediary to transfer power between your engine’s pistons and its crankshaft. Having such a pivotal role in your engine means you have to reach a balance between rod weight and strength. Connecting rods have to be strong enough to withstand all the horsepower and tension that is generated, but light enough so as not to become an impediment to the power transfer. This balance between weight and strength is going to change from one performance application to the next.
4340 steel is a chrome-moly alloy with high tensile and compressive strength, so it is well suited to the constant pushing and pulling action inside an engine. As a company that has its own foundry and laboratory, PowerBore is able to provide its customers with absolute certainty in the chemistry and properties of the rods we supply.
