DIESELR EGR Upgrade Kit (2010-2012 Cummins 6.7L - CAB & CHASSIS)

The Cummins 6.7L EGR Upgrade Kit for 2010-2012 cab and chassis trucks replaces the factory exhaust gas recirculation loop on Ram 3500, 4500 and 5500 chassis cab models. Every plate, bracket and fastener is cut for the chassis cab layout, which mounts and routes differently from the 2500/3500 pickup. The pickup version does not bolt up in its place.

These are pre-SCR trucks: 2010 through 2012 run EGR, a diesel oxidation catalyst, a NOx adsorber and a DPF, with no DEF system.

Why the factory loop becomes a service item

The EGR cooler runs hot exhaust gas against engine coolant. Its internal tubes crack from constant thermal cycling and leak coolant into the intake or exhaust, which shows up as unexplained coolant loss, white exhaust, a sweet smell and overheating. The valve pintle carbons up from recirculated soot and sticks, and that carbon buildup is the number one cause of a P042E code, along with rough running and poor throttle response. Both are high-mileage wear items and incidence rises past roughly 100,000 miles.

On an off-road truck, replacing the loop takes out the coolant-side failure point and the carbon-fouling valve, restores intake airflow, and keeps recirculated soot out of the intake tract.
