2011-2016 vs 2017-2019 vs 2020+ 6.7 Power Stroke: Which Generation Is Best?

The Ford 6.7L Power Stroke has been in production since 2011 and has gone through three distinct generations. Each brought significant improvements, but also introduced new challenges. Here's a comprehensive comparison to help you understand the differences.

From the 1st generation DualBoost turbo to the 3rd generation forged pistons — each era brought major improvements.

1st Generation (2011-2016)

Power: 390-400 HP / 735-800 lb-ft torque

The original Ford-designed diesel (replacing the Navistar-built 6.4L) was a clean-sheet design. Ford wanted complete control over their diesel program, and the result was impressive — but not without growing pains.

Key Features:

• Twin-compressor DualBoost turbocharger
• Bosch CP4.2 high-pressure fuel pump
• Piezo fuel injectors
• Compacted Graphite Iron (CGI) block
• Plastic oil pan (2011-2012)

Common Problems:

• Plastic oil pan cracking (2011-2012, replaced with steel in 2013+)
• DualBoost turbo bearing failure
• Radiator crossover tube leaks
• EGR cooler failure
• CP4 fuel pump failure

Best For: Budget-conscious buyers who want a solid 6.7L platform at the lowest price point.

2nd Generation (2017-2019)

Power: 440-450 HP / 860-935 lb-ft torque

The 2015 update was the most significant revision. Ford addressed many first-gen issues and substantially increased power output.

Key Improvements Over 1st Gen:

• Single VGT (Variable Geometry Turbo) GT37 replaces DualBoost
• Strengthened cylinder heads
• IROX polymer-coated bearings
• Upgraded oil cooler design
• Improved EGR system
• Higher injection pressures (up to 30,000 PSI)

Common Problems:

• CP4 fuel pump failure (still present)
• EGR cooler leaks (improved but not eliminated)
• Crankshaft damper failure
• DEF system issues

Best For: The sweet spot of power, reliability, and value. The most popular generation we remanufacture.

3rd Generation (2020-Present)

Power: 475-500 HP / 1,050-1,200 lb-ft torque

The latest generation is a powerhouse, with the highest output of any light-duty diesel in America.

Key Improvements Over 2nd Gen:

• Forged steel pistons (replacing aluminum)
• Strengthened block casting
• 36,000 PSI fuel injection pressure
• Enhanced VGT turbocharger
• Paired with 10-speed TorqShift transmission
• Improved emissions system

Common Problems:

• Still relatively new, fewer known long-term issues
• CP4 fuel pump remains a concern
• DEF system complexity
• Higher parts cost due to newer technology

Best For: Maximum towing capacity and the latest technology. Best choice for heavy commercial use.

Head-to-Head Comparison

Our Recommendation

For most truck owners, the 2nd Generation (2017-2019) offers the best overall value. It fixed the major issues from the 1st generation, delivers strong power, and is priced in the middle of the range. The 3rd generation is the best performer but comes at a premium.
