2010-2018 4th Gen 6.7L Cummins Parts & Performance

2010-2018 Dodge Ram 2500 & 3500 6.7L Cummins Performance Parts & Upgrades

Take the towing capacity, throttle responsiveness, and heavy-duty drivetrain reliability of your Ram truck to the next level with premium 2010-2018 6.7L Cummins 4th Gen performance parts from Full Force Diesel. Representing one of the most popular and versatile eras in modern diesel history, the 4th Generation 6.7L Cummins inline-six combines a high-pressure Bosch common-rail injection system with exceptional chassis refinement. Whether you're daily driving a non-DEF early 4th Gen or utilizing a late-model truck with an advanced high-output platform, targeted aftermarket upgrades are key to overcoming factory bottlenecks and safeguarding your powertrain.

Optimizing VGT Airflow & Overcoming Turbo Actuator Limits

The 2010-2018 6.7L Cummins relies on a smart Holset variable-geometry turbocharger (VGT) to provide immediate low-end boost and an integrated exhaust brake function. However, the factory plastic intake track and highly restrictive exhaust downpipe create thermal bottlenecks that raise your exhaust gas temperatures (EGTs) while towing.

• Cold Air Intakes & Intercooler Piping: Upgrading to a premium enclosed cold air intake system paired with mandrel-bent 3-inch aluminum intercooler charge pipes improves air velocity and shortens turbo spool times.
• Billet Compressor Wheels & Actuators: The factory electronic VGT actuator is a notorious failure point due to internal soot accumulation. Replacing a worn unit with a heavy-duty upgraded actuator or installing a drop-in high-performance turbocharger with a billet compressor wheel ensures crisp boost delivery and lower operating temperatures under load.

Reinforcing the 68RFE & Aisin Transmissions for Heavy Towing

With massive common-rail torque readily available through basic electronic tuning, reinforcing the 4th Gen drivetrain is a top priority for truck owners:

• Transmission Optimization: Depending on your truck's configuration, you're running either the Chrysler 68RFE 6-speed automatic or the commercial-grade Aisin AS69RC automatic transmission (standard on high-output models). For the 68RFE, upgrading to a deep aluminum oil pan, an auxiliary fluid cooler, and an upgraded valve body prevents clutch slippage. For the Aisin, regular fluid changes and high-capacity internal filters are vital to prevent line-pressure issues.
• Fuel System Longevity: While 4th Gen trucks feature an improved factory lift pump, high-pressure common-rail components remain highly sensitive to water and particulate contamination. Installing a frame-mounted fuel-air separation system removes entrained air and microscopic debris before it can compromise your high-pressure pump or fuel injectors.
