Discover the full potential of your 2013–2018 Ram 2500/3500 6.7L Cummins with Diesel Power Source performance upgrades. Our turbos and manifolds are engineered for superior airflow, efficient boost control, and cooler EGTs, all while maintaining long-term reliability and clean fitment.

Built specifically for Late 4th Gen 6.7 Cummins trucks, each upgrade is designed to enhance real-world performance—whether you’re towing, daily driving, or building for power. Our parts are cast from high-nickel alloys, CNC-machined for precision, and tested under extreme conditions to ensure dependable performance and long service life.

Why Upgrade Your 2013–2018 6.7 Cummins?

  • Cooler Exhaust Temps: Improve airflow and reduce backpressure to drop EGTs for better reliability under load.
  • Faster Spool-Up: Optimized runner and collector geometry delivers quicker boost response and stronger midrange torque.
  • More Towing Power: Experience smoother power delivery and better control when hauling heavy loads.
  • Stronger Materials: Thick-wall casting prevents cracking, warping, or leaks from repeated heat cycles.
  • Direct Fitment: Clean installation with OE-style alignment ensures trouble-free installs and proper sealing.

Top Upgrade Options for the Late 4th Gen Cummins

  • Stock-Replacement Manifolds: Direct-fit solutions for emissions-equipped trucks that improve flow and temperature stability.
  • T4 Performance Manifolds: Ideal for larger turbo setups that require higher airflow without losing street drivability.
  • S300 or S400 Turbo Upgrades: Choose between balanced response (S300) or higher airflow (S400) depending on your build goals.
  • Turbonator® VGT Upgrades: Our patented ball-bearing VGT delivers lightning-fast spool, torque gains, and built-in exhaust braking.
  • Compound Turbo Kits: For maximum efficiency and wide powerband control—perfect for towing, sled pulling, or performance applications.

Fitment

All Diesel Power Source manifolds and turbos in this category are designed for 2013–2018 Ram 2500 and 3500 6.7L Cummins applications. These parts are compatible with both automatic and manual transmission trucks and are engineered for clean fitment with factory intercoolers and sensors.

Installation Tips & Maintenance

  • Always replace gaskets and use high-temp anti-seize on all studs and fasteners.
