Why upgrade your Dodge/Ram Cummins with performance parts
More power and torque
Performance components improve airflow and reduce backpressure so your truck accelerates quicker, tows stronger, and holds speed on grades.
Better fuel efficiency
Improved charge air and exhaust flow help the turbo operate in its sweet spot, supporting cleaner combustion under load.
Durability you can count on
Thick-wall castings, reinforced partitions, and precision-machined flanges resist cracking, warping, and leaks through repeated heat cycles.
Build it your way
From stock-replacement parts to S300/S400 turbos and compound-over-stock kits, choose upgrades that match towing, daily driving, or high-fuel goals.
How to choose the right upgrade path
- Towing & daily: Earlier spool and stable EGT. Consider stock-replacement manifolds and S300-class turbos.
- Street performance: Mid-size singles with freer housings for stronger midrange while keeping street manners.
- High-fuel builds: Larger S400 or compound paths for airflow headroom; plan converter, gearing, and cooling.
Fitment checklist
- Confirm engine family/year and turbo flange (T3/T4/T4i) before ordering.
- Check downpipe route, intercooler path, steering and A/C clearances.
- Plan supporting items: gaskets, hardware, heat shielding, and monitoring ports.
Install & first-drive notes
- Use new gaskets and quality hardware; torque in sequence on a cold engine.
- Pressure test the charge-air system before first start; verify no pre-turbine leaks.
- Monitor boost, EGT, and (if equipped) drive pressure on initial towing runs; re-check fasteners after heat cycles if specified.

These parts are designed to improve power, drivability, and reliability in both street and work-truck applications.
A performance turbo can reduce turbo lag, increase horsepower and torque, lower EGTs under load, and improve throttle response. Many customers also see improved towing performance and overall engine efficiency when properly matched with supporting mods.
Some upgrades, such as compound turbo kits or larger single turbos, may require custom tuning to run properly and safely. Other bolt-on components can be installed without tuning. Always check the product description or contact our team to confirm tuning requirements.
Yes. Many of our Dodge Cummins performance products are engineered with towing in mind, focusing on controlled boost, lower exhaust temperatures, and long-term durability. We also offer options specifically intended for daily-driven and work trucks.
The best upgrade depends on your goals, such as towing, daily driving, or high horsepower. Diesel Power Source offers expert guidance to help you choose the right turbo, manifold, or kit based on your truck, budget, and performance goals.
