From turbo systems and exhaust manifolds to install hardware and replacement parts, Diesel Power Source engineers clean-fit, durable solutions for daily work trucks, tow rigs, and high-power builds. Lower your EGTs 200-300°F, improve throttle response, and protect your engine for the long haul.
Proven thermal management for heavy towing
Improved low-end torque and passing power
Thick-wall castings resist cracking and warping
Direct bolt-in for Dodge/Ram chassis
Performance components improve airflow and reduce backpressure so your truck accelerates quicker, tows stronger, and holds speed on grades without excessive throttle.
Improved charge air and exhaust flow help the turbo operate in its sweet spot, supporting cleaner combustion under load and reducing wasted fuel.
Thick-wall castings, reinforced partitions, and precision-machined flanges resist cracking, warping, and leaks through repeated heat cycles.
From stock-replacement parts to S300/S400 turbos and compound-over-stock kits, choose upgrades that match towing, daily driving, or high-fuel goals.
Earlier spool and stable EGT. Consider stock-replacement manifolds and S300-class turbos for 150-200°F cooler temps and instant response.
Mid-size singles with freer housings for stronger midrange while keeping street manners. Best balance of fun and usability.
Larger S400 or compound paths for airflow headroom; plan converter, gearing, and cooling. 200-300°F cooler EGTs even at 700+ HP.

Why this matters for engine life:
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.
Compounds use TWO turbos working together—small primary + large secondary.
