6.7 Cummins Stock Replacement Parts

6.7L Cummins Stock-Replacement Parts (Direct-Fit OEM Alternatives)

Diesel Power Source 6.7L Cummins stock-replacement parts restore factory performance with upgraded durability. Our direct-fit turbos and exhaust manifolds meet or exceed OEM specifications for Ram 2500 and 3500 trucks while improving sealing and long-term reliability.

This page is dedicated to OEM-fit, emissions-compatible replacements for work trucks, daily drivers, and fleet maintenance. If you are planning larger singles, compounds, or T4 conversions, see the related performance links at the bottom. Each product page lists year-specific notes, included hardware, and installation guidance.

What’s covered (6.7L Cummins model years)

  • 2007.5–2012: Direct-fit hot-side components that maintain OE spool and drivability on early 4th Gen trucks.
  • 2013–2018: Replacement turbos and manifolds with correct flange geometry and sensor/actuator provisions for late 4th Gen.
  • 2019–2024: OEM-equivalent fitment for 5th Gen bays, built to handle repeated heat cycles and high-mile routes.

Why choose DPS 6.7 stock-replacement parts

  • True OEM fitment: Correct flange patterns, wastegate/actuator locations, and sensor ports for a straightforward install.
  • Built to last: Thick-wall, high-nickel castings and precision-machined flanges help reduce warping, cracking, and leaks.
  • Stable EGT and boost control: Clean internal flow supports consistent turbine speed and factory torque delivery under load.
  • Emissions-system friendly: Designed to operate with factory aftertreatment when installed as directed.
  • Fleet-ready reliability: Repeatable installs and dependable sealing for trucks that rack up miles.

How to pick the right 6.7 replacement

  • Match your OE part: Confirm model year, turbo/manifold flange, downpipe style, actuator type, and sensor/port requirements.
  • Plan supporting items: Fresh gaskets, studs/nuts, heat shields, and any crush washers needed for a durable seal.
  • Usage profile: For stock power and towing, choose like-for-like replacements. If you expect future horsepower increases, review our performance categories instead of OEM-fit parts.

Fitment checklist

  • Verify T3 vs T4/T4i flange and downpipe connection for your year.
  • Confirm wastegate or actuator style and sensor provisions (MAP, EGT, drive pressure where used).
  • Inspect cylinder-head and turbo mating faces; address warpage or carbon tracking before install.

Install and first-drive tips

  • Use new gaskets and quality hardware; torque fasteners in sequence on a cold engine.
  • Pressure-test charge-air and pre-turbine joints before first start to catch leaks.
  • Re-check fastener torque after initial heat cycles where the service manual specifies.

Frequently asked questions

Do I need tuning for a stock-replacement turbo or manifold

No. Like-for-like replacements are designed to run on factory calibration. If turbo size or fueling changes, tuning may help drivability and EGT control.

Will these parts work with emissions equipment

Yes. These OEM-fit components are intended to operate with factory systems when installed as directed. Always follow local regulations.

How do I confirm the correct part for my 6.7

Match year/engine variant, flange type, actuator style, and sensor/porting. If uncertain, contact us with your VIN and current part numbers.

What symptoms suggest my turbo or manifold needs replacement

Exhaust leaks or soot tracking, boost loss, slow spool, excessive shaft play, whistle or grinding noises, or repeated EGT spikes under normal load.

Are DPS replacements stronger than OEM

Our thick-wall castings and precision machining are engineered for durability and sealing through repeated heat cycles, meeting or exceeding OE performance in stock applications.
