3811995 Cummins K19 Connecting Rod

Product Description

The 3811995 Cummins connecting rod is an engine internal component for selected Cummins K-Series engine applications. It connects the piston to the crankshaft and transfers combustion force through the crank mechanism. During engine operation, the connecting rod works under repeated mechanical loads, so correct part selection is essential for engine repair and rebuilding.

RJT PARTS supplies aftermarket engine parts for international distributors, diesel engine repair workshops, and wholesale buyers. If you are sourcing a 3811995 connecting rod for Cummins K19 or KTA19 engines, please share the engine model and serial number with our team. This information helps us check the application before you place an order.

Product Specifications

Application and Ordering Information

Parts catalogs list 3811995 for selected K19, KTA19GC, QSK19, and QSK19G engine applications. However, engine configurations and production versions can differ. Therefore, always compare the part number with your engine parts catalog or service records before ordering.

The number 3043911 appears as an earlier part number in a parts reference. Do not assume that every engine using 3043911 accepts 3811995 without checking the applicable parts information.

For engine rebuilding projects, buyers may also need matching connecting rod bearings, pistons, and piston ring sets. Check each component separately to confirm the correct size and application.

You can explore our [Cummins Connecting Rods] and [Connecting Rods] categories to find related replacement parts. For a broader range of engine components, visit our [Engine Parts] category. If your project also requires piston components, see our [Piston Ring Sets] page.

Verify Cummins Engine Parts and Fitment

Before ordering a 3811995 Cummins connecting rod, confirm the engine model and serial number. Different engine configurations may require different components, even within the same engine series. Therefore, check the applicable parts information before placing a bulk order.

For additional reference, visit Cummins QuickServe Online to access engine-specific parts and service information. This step helps buyers check part references and reduce the risk of ordering an incompatible component.

Check Related Cummins Connecting Rod References
