2007.5-2009 3rd Gen 6.7L Cummins Parts & Performance

2007.5-2009 Dodge Ram 2500 & 3500 6.7L Cummins Performance Parts & Upgrades

Maximize the towing power, internal engine efficiency, and long-term reliability of your heavy-duty truck with premium 2007.5-2009 6.7L Cummins 3rd Gen performance parts from Full Force Diesel. Introduced midway through the 2007 model year to replace the legendary 5.9L, the early 6.7L Cummins inline-six brought a massive increase in displacement, faster turbo spool times, and a highly advanced Bosch high-pressure common-rail fuel system to the final years of the classic 3rd Generation chassis. Because these specific model years introduced early-generation diesel emissions systems and the electronic 68RFE automatic transmission, targeted aftermarket support is vital to optimize your truck's true potential.

Enhancing Variable-Geometry Turbo Response & Airflow

The foundational upgrade for any early 6.7L Cummins is opening up its restrictive factory induction and exhaust plumbing. The 2007.5-2009 motor utilizes an advanced Holset variable-geometry turbocharger (VGT) that provides incredible low-end torque but is highly sensitive to excessive exhaust gas temperatures (EGTs) and soot loading.

• Cold Air Intakes & Downpipes: Installing a high-flow cold air intake system delivers a dense charge of cool air to the compressor wheel, while upgrading to a mandrel-bent turbo downpipe drastically lowers backpressure.
• Intercooler Charge Pipes: Replacing the factory flexible rubber boots with mandrel-bent 3-inch aluminum hot and cold-side intercooler tubes eliminates potential boost leaks and sharpens off-the-line throttle response.

Bulletproofing the 68RFE Transmission & Steering Framework

Managing the immense torque of a tuned 6.7L Cummins requires reinforcing your drivetrain and front-end geometry:

• 68RFE Transmission Protection: The 2007.5 truck marked the debut of the 68RFE 6-speed automatic transmission. Under heavy towing or aggressive tuning, the factory overdrive clutches and valve body are known weak points. Upgrading your transmission with a deep aluminum fluid pan, a heavy-duty torque converter, and upgraded valve body components is highly recommended to keep fluid temperatures cool and shifts crisp.
• Fuel System Lift Pumps: Protect your high-pressure Bosch CP3 injection pump and precision common-rail fuel injectors by installing a frame-mounted fuel lift pump or fuel-air separation system to continuously supply pure, air-free fuel pressure.
• T-Style Steering Upgrades: The 2007.5-2009 heavy-duty Ram front ends are notorious for steering wander. Upgrading your truck's early Y-style steering linkage to the updated heavy-duty T-style steering assembly completely transforms handling, tracking, and tire wear.
