Our Compound Kits are excellent for towing. But for our best Towing Compounds/Twins are any of the kits using the 62mm compressor wheels, or the Stock Turbo.
Our Cummins compound turbos are the best upgrade for Dodge Cummins pickups. They greatly improve diesel performance.
Why Our Compound Turbos Work So Well on your Cummins engine:
- More cool air enters the cylinders because the dual-stage compressors work together in their most efficient zones. The boost air is typically over 100 cooler per pressure made than from a single turbo.
- The air that enters the cylinder has higher pressure. This brings the boost pressure and exhaust drive pressures close to a 1:1 ratio. The intake stroke can actually produce power.
- Extra air molecules in the cylinder do not take part in combustion. These molecules carry heat out of the cylinder, much like a jet engine stays cooler. It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all the fuel.
- Engineers design Diesel Power Source compound turbo 5.9 Cummins turbo kits using CAD/CAM software. They also use CFD (Computational Fluid Dynamics) testing.
- Our Cummins compound turbos give a factory-like fit with the highest performance possible. Everything fits like the factory built it, and it performs so well. You’ll wonder how you ever drove without them.

***On 2nd Gen trucks with automatic transmission. You will need to remove, bypass, or relocate the trans oil heat exchanger on the side of the engine block to the frame. We sell the relocation kits for $149, select in the drop down.
***Only 2002 and older kits come with a downpipe, 2003 and newer kits bolt right to the factory exhaust.
***These kits do NOT have a CARB exemption. However our exhaust manifolds do.
