Cummins Connecting Rods

Every component in your marine diesel engine contributes to your boat's performance. To keep your boat on the water, you need to perform regular maintenance and replace parts that become worn and damaged. At Diesel Pro Power, we offer an extensive online selection of replacement parts for Cummins marine engines, including Cummins connecting rods. We make it easy to find the exact components you need to get your boat running again.

Also known as conrods, connecting rods play an essential role in diesel engines. These components connect the piston to the crankshaft or crank, transforming the piston's reciprocating motion into rotary motion and allowing the boat to move. A conrod can become damaged due to usual wear and tear as well as during hydrolock, which happens when water gets into the piston chamber. A damaged connecting rod can impact your boat's performance and lead to further damage, so it's important to consider repairs as soon as you notice a problem.
