2019-2026 5th Gen 6.7L Cummins Parts & Performance

2019-2026 6.7L Cummins 5th Gen Ram 2500 & 3500 Performance Parts

Maximize the towing capability, engine efficiency, and long-term reliability of your late-model Ram 2500 or 3500 with premium 2019-2026 6.7L Cummins 5th Gen performance parts from Full Force Diesel. Built on Cummins' proven B6.7 architecture, the 5th Gen platform brought a stronger block, revised turbocharging, and Ram's most advanced factory tuning yet to the heavy-duty truck segment. Whether you're fortifying your fuel system, upgrading transmission cooling, or optimizing airflow, our precision-engineered aftermarket components are built specifically for your exact truck.

Protecting Your Fuel System from CP4 Failure

Like other modern common-rail diesels, the 5th Gen 6.7L Cummins relies on a high-pressure fuel pump that's highly sensitive to contamination. If it fails from fuel starvation or debris, it can send metal shavings through your entire fuel system — a repair that can run into the thousands. Installing a disaster prevention kit redirects that debris away from your injectors before it spreads, while an upgraded lift pump or fuel-air separation system keeps your high-pressure components running on clean, consistent fuel from the start.

Transmission Upgrades: Know Your Configuration

Depending on your exact truck, your 5th Gen Ram runs one of two very different automatic transmissions — the 68RFE (common on 2500 models) or the heavier-duty Aisin AS69RC (standard on higher-GVWR 3500 and dually configurations). Because these transmissions have different cooling needs, pan capacities, and upgrade paths, always confirm which one your truck has before shopping transmission parts. We carry heavy-duty pans, coolers, and upgrades matched to both platforms to keep fluid temperatures in check under heavy towing.

Airflow, Turbo, and Exhaust Upgrades

Once your fuel and drivetrain foundation is secured, a high-flow cold air intake, upgraded turbo components, and a free-flowing exhaust system work together to lower EGTs, quicken spool times, and unlock real power gains — especially valuable when towing heavy in the 5th Gen's revised, more powerful factory tune.

At Full Force Diesel, we carry a complete lineup of parts to protect, maintain, and build your 5th Gen Cummins. Browse the full subcategory directory below to find exactly what your Ram 2500 or 3500 needs.
