Welcome to the specialized performance hub for the 5th Gen 6.7 Cummins (2019-2024). Powering the latest 5th Gen Ram HD lineup, this engine platform represents the pinnacle of diesel engineering, boasting a staggering 1,000 lb-ft of torque in high-output factory trim. However, increasingly complex emissions hardware often acts as a bottleneck for thermal efficiency and fuel economy. Whether you are chasing extreme towing power or long-range cruising durability, understanding the modification ceiling of the 5th Gen Cummins is the first step to fully unleashing this powerhouse.

Universal Fit
The 2019-2024 6.7L Cummins features a significant structural upgrade with its Compacted Graphite Iron (CGI) block, designed to handle higher combustion pressures than previous generations. However, this high-output capability comes with more sophisticated sensor monitoring.
A critical factor for owners is the warranty status. If your truck is approaching or has surpassed the factory warranty period, performance modification becomes a strategic move. Removing failure-prone emissions components not only prevents expensive out-of-warranty repairs but also significantly reduces the engine's thermal load by optimizing exhaust flow. Even for those still within the warranty window, many enthusiasts opt for upgrades tailored for "Off-road or Race" scenarios, as the robust foundation of the 5th Gen 6.7 Cummins allows for massive gains in both reliability and power through simple fluid dynamic optimizations.
To address the complex emissions architecture of the 6.7 cummins engine, SuncentAuto provides rigorously tested hardware. For those seeking maximum ROI, we offer official integrated bundles designed to eliminate factory bottlenecks and fully unleash your 5th Gen's raw power:
EGR Delete Kit for Cummins: Completely halts the recirculation of soot-heavy exhaust into the intake manifold, preventing carbon buildup and ensuring the engine breathes only clean air.
6.7 Cummins DPF Delete Kit: Removes the most restrictive components from the exhaust path, eliminating backpressure to drastically improve turbo spool-up and slash EGTs.
Performance Tuner: The "brain" of the system, responsible for bypassing security gateways and remapping logic—a mandatory prerequisite for hardware upgrades.
Exhaust (Downpipe-Back): A complete piping solution from the turbo downpipe rearward, providing an unobstructed path for exhaust gases.
High-Flow Muffler: Delivers a deep, aggressive diesel growl without compromising exhaust flow velocity.
The Foundation Bundle (EGR + DPF + Tuner): This comprehensive 6.7 Cummins diesel delete kit is the essential choice for 5th Gen owners. By synchronizing hardware and software, it provides a one-stop solution to internal engine wear while ensuring a CEL-free operation after DPF removal.
The Ultimate Integration Package (EGR + DPF + Tuner + Downpipe-Back): Our premier "all-in-one" solution for maximum performance. By integrating the full exhaust system with our delete suite, you achieve total path optimization from the intake to the tailpipe, unlocking the platform’s full 1,000+ lb-ft torque potential.
The engine bay of the 5th Gen Ram HD is more compact and electronically advanced, making precise installation and data-driven maintenance vital for peak performance.
Oil Change Intervals: While soot is reduced post-modification, the 5th Gen’s hydraulic lifters demand high shear stability. We recommend oil changes every 5,000 to 7,500 miles; never exceed 10,000 miles.
Oil Specifications: Use only CK-4 rated synthetic oils meeting the CES 20086 standard (e.g., Shell Rotella T6 or Mobil 1 Delvac). A viscosity of 10W-30 is standard, while 5W-40 is preferred for extreme temperatures or heavy hauling to protect the delicate valvetrain.
Fuel Filtration: Replace the dual fuel filter system every 15,000 miles to safeguard the high-pressure common rail system from moisture and contaminants.
Don't let factory emissions restrictions throttle the potential of your 5th Gen 6.7 Cummins. Whether you are chasing absolute reliability for heavy-duty hauling or seeking superior fuel economy during highway cruising, SuncentAuto’s professional solutions provide the power and efficiency you demand.
From our foundational diesel delete kit to fully integrated tuner solutions, every component we offer is engineered to unleash the hidden power of the 5th Gen platform. Shop our official recommended bundles today—untether your 5th Gen Ram HD and experience the raw, aggressive, and efficient diesel performance it was built to deliver.
Yes. The 5th Gen 6.7 Cummins is equipped with a Security Gateway Module (SGM). Before installing any diesel delete kit, a compatible tuner or bypass cable is required to communicate with the ECU for proper software calibration.
Once the egr delete kit is installed, exhaust gas is no longer recirculated into the engine, effectively stopping soot accumulation at the source. Your intake manifold and valves will remain clean, eliminating the need for periodic carbon-related maintenance.
The 6.7 cummins engine introduced hydraulic lifters in its 5th generation to reduce maintenance, making it sensitive to oil purity. Removing the DPF reduces the risk of fuel dilution, which—when paired with CK-4 synthetic oil—actually provides superior protection for the valvetrain.
While partial deletes are possible, a full downpipe-back exhaust ensures a consistent diameter (typically 4" or 5") throughout the system. This eliminates all exhaust bottlenecks, resulting in the lowest possible EGTs and faster turbo spool-up.
You will see a significant improvement. By optimizing the torque curve via a tuner and reducing backpressure with hardware deletes, the truck responds much better under load. Additionally, lower EGTs allow you to maintain power longer during heavy pulls without heat-soaking the engine.
