Keep Your Cummins Running Strong With The Right Fix

If your RAM Cummins is starting to show signs of electrical gremlins or oil seepage around the valve cover, it might be time to swap in a fresh valve cover gasket with the integrated harness. This OEM Cummins 5367847 gasket and injector wiring harness combo is the same quality you'd get at a dealership, but without the inflated price. Whether you're working on a high-mileage 2006-2007 5.9L or a 2007.5-2023 6.7L, this part fits perfectly and helps eliminate common issues like oil contamination in the injector connections or failed electrical signals that can lead to misfires. It’s a smart upgrade if you’re chasing down intermittent rough idle problems or trying to stop that persistent valve cover leak. The built-in harness simplifies installation, especially for DIYers who want to knock it out in the garage without chasing down separate components. This is the kind of part that quietly keeps your truck running clean and smooth, mile after mile. If you depend on your Cummins for daily driving, towing, or work, replacing worn gaskets and connectors like this is a no-brainer to maintain long-term reliability.

Built To Match OEM Specs With Heavy Duty Durability

This Cummins 5367847 valve cover gasket and injector wiring harness assembly is designed to meet exact factory specifications for 2006-2007 5.9L and 2007.5-2023 6.7L RAM trucks. It replaces previous part numbers 3975641 and 5264950 and comes with a molded gasket that resists heat, oil saturation, and long-term compression. The integrated wiring harness ensures proper injector signal transmission and maintains a clean, sealed connection to prevent contamination and shorts. Over time, factory harnesses can crack or corrode, especially in high-heat engine bays, leading to poor performance and fault codes. This unit restores OEM-level operation with no splicing, cutting, or guesswork required during install. The gasket edge seals tightly against the valve cover, helping to eliminate leaks that can lead to oil buildup or messes in the engine compartment. Whether you're doing routine maintenance or chasing down a hard-start issue, this direct-fit replacement is a smart investment in engine longevity and performance.
