A Legacy of Power: The Cummins 6.7L Diesel Engine

For over three decades, the partnership between RAM and Cummins has redefined diesel excellence, setting benchmarks for power, dependability, and technological innovation. This collaboration has armed RAM trucks with engines that deliver exceptional torque and long-term durability—ideal for heavy-duty workloads, off-road adventures, and the demands of daily driving.Introduced in 2007 and still in production today, the Cummins 6.7L diesel engine stands as the backbone of the heavy-duty trucking industry. Renowned for its bulletproof build, brute towing power, and cutting-edge engineering, it has become the standard powertrain for RAM heavy-duty trucks, evolving through three generations to meet stricter emissions standards while pushing performance limits.

Third Generation (2007-2009): The Game-Changer

Debuting in mid-2007, the 6.7L Cummins replaced the iconic 5.9L engine that had powered Dodge trucks since 1989. With increased displacement, enhanced power output, and advanced emissions control technology, it immediately established itself as a class leader.

Key Specifications

• Maximum Horsepower: 350 hp
• Maximum Torque: 650 lb-ft

Emission Control Systems

• Exhaust Gas Recirculation (EGR) System: Reduces nitrogen oxide (NOx) emissions by recirculating exhaust gases back into the combustion chamber.
• Diesel Particulate Filter (DPF): Traps particulate matter (soot) in exhaust to minimize smoke and air pollution.
• Variable Geometry Turbocharger (VGT): Enhances low-end torque and improves throttle response for smoother, more responsive performance.

Common Issues & SuncentAuto Solutions

• DPF Clogging: Resolved with our 6.7L Cummins DPF Delete Pipe—eliminates frequent regeneration cycles, clogging risks, and maintenance costs.
• Cylinder Head Gasket Failures: Pair with high-strength cylinder head bolts (or replace with OE gaskets) for enhanced durability.
• Oil Dilution: DPF delete reduces unburned fuel buildup in oil, preserving engine health.
• EGR Cooler Malfunctions: Our EGR Delete Kit removes the faulty component, improving intake efficiency and eliminating carbon deposits.

Fourth Generation (2010-2018): Performance Redefined

The fourth-generation RAM trucks elevated the Cummins 6.7L engine to new heights, with significant performance upgrades. Featured in RAM 2500, 3500, 4500, and 5500 heavy-duty models, this engine gained widespread acclaim for its increased power, advanced emissions tech, and rock-solid reliability—all while meeting stricter 2010 EPA standards.

Key Specifications

• Horsepower: 325 hp
• Torque: 750 lb-ft

Enhanced Emission Control Systems

• Diesel Particulate Filter (DPF): Refined design for more effective soot capture and longer service intervals.
• Selective Catalytic Reduction (SCR) System: Introduced to convert NOx into harmless nitrogen and water using Diesel Exhaust Fluid (DEF), complying with stricter emissions rules.
• Optimized EGR System: Balances emissions reduction with improved fuel efficiency, minimizing the performance tradeoffs of earlier designs.

Fifth Generation (2019-Present): The Heavy-Duty Benchmark

Launched under the "Heavy Duty" banner, the latest generation of RAM trucks continues the 6.7L Cummins legacy, powering RAM 2500, 3500, and chassis cab models. This engine delivers industry-leading performance, innovative emissions technology, and unmatched durability—meeting the most rigorous global emissions regulations while delivering unrivaled towing capacity and reliability for serious truck users.

Key Specifications

• Horsepower: 370 hp
• Torque: 850 lb-ft

Next-Gen Emission Control

• SCR System: Works seamlessly with DEF to achieve near-zero NOx emissions, with improved efficiency and reduced DEF consumption.
• DPF System: Higher-efficiency filtration with extended cleaning intervals, reducing downtime and maintenance costs.
• Improved EGR System: Reduces exhaust emissions without sacrificing fuel economy or engine responsiveness, thanks to precision engineering.

Unlock Maximum Potential: Modification Options

The Cummins 6.7L engine is inherently modular, offering massive modification potential to amplify its natural strength. SuncentAuto’s curated kits are designed to remove factory restrictions and optimize every aspect of performance:

• EGR Delete Kit: Eliminates carbon buildup in the intake manifold, improves airflow, and reduces engine stress—boosting both power and fuel efficiency.
• DPF Delete Pipe & Straight-Through Exhaust: Maximizes exhaust flow, eliminating DPF clogging and regeneration issues while unlocking hidden horsepower and torque. The result is a deeper, more aggressive exhaust note and improved throttle response.
• ECU Tuning: Pair with our delete kits to adjust engine parameters, further enhancing horsepower, torque, and fuel economy—tailoring performance to your driving style.
• CCV/PCV Reroute Delete Kit: Prevents oil vapor from re-entering the intake system, reducing carbon deposits and preserving engine cleanliness for long-term durability.
