Dodge / Ram Cummins 5th Gen (2019–2024) FAQs

The 5th gen represents the most significant leap forward in Cummins history.

Major improvements over 2013-2018:

Massive torque increase: 1,075 lb-ft in HO trim (up from 930 lb-ft). Most powerful production Cummins ever.
Stronger internals: Forged pistons, enhanced rods, beefed-up block to handle extreme factory torque
Advanced ECM: Most sophisticated programming ever; responds incredibly well to tuning
Larger turbo option: HO models get HE400VG (vs. HE300VG); better flow from factory
Redesigned chassis: Completely new 5th gen Ram body; best ride, quietest, most comfortable
Better emissions: Even more advanced DEF/SCR; cleaner, more efficient

Why 2019-2024 is ultimate platform:

Highest power ceiling of any Cummins (1,000-1,200+ HP achievable)
Strongest factory components mean less internal work needed
Best transmission options (Aisin standard on HO)
Most refined for daily driving (quietest, smoothest, best tech)
Advanced ECM unlocks incredible tuning potential

Latest 6.7L supports all turbo options; HO baseline already strong.

HE400VG VGT upgrade (keep all factory features):

Turbonator® HE400VG or enhanced VGT: Upgraded variable geometry
Power range: 550-650 HP reliably
Benefits: Keeps exhaust brake, tow/haul, emissions compatibility, 150-225°F cooler EGTs
Best for: Daily drivers, heavy towing, emissions compliance, want factory features
Note: HO models already have excellent HE400VG; upgrade provides refined improvements

S300 fixed-geometry singles:

S366, S369, S372: For 600-750 HP
Benefits: Quick spool, 200-250°F cooler EGTs, no VGT complexity, strong midrange
Limitation: Lose exhaust brake and VGT features
Best for: Performance builds, don't need exhaust brake, want simplicity

S400 singles (serious power):

S475, S480, S483: For 750-900 HP
Benefits: Massive airflow, handles extreme fueling, competition-ready
Limitation: Lag below 2000 RPM; dedicated use recommended
Best for: Drag racing, sled pulling, dyno queens

Compound turbo systems (ultimate):

S300/S400 or S400/S400: For 800-1,100+ HP
Benefits: Zero lag, 250-300°F cooler EGTs, insane power that's drivable daily
Best for: Extreme towing (35k+ lbs), competition, ultimate street trucks
Advantage: Latest 6.7L + Aisin + compounds = most capable combo possible

EGT improvements: 150-300°F; critical with massive factory torque.

Stock HE400VG baseline (HO with aggressive tune):

Towing 25,000 lbs up 6% grade with 600 HP tune: 1,175-1,275°F
HE400VG better than earlier turbos but still restrictive at high power

After Turbonator® HE400VG or enhanced VGT:

Same load, same tune: 1,025-1,125°F (150-200°F cooler)
Improved design and flow = significant thermal improvement
Keeps exhaust brake for safety

After S369 or S372 fixed-geometry single:

Towing 28,000 lbs, 650 HP: 1,000-1,100°F (175-275°F cooler)
Excellent airflow capacity = clean combustion, safe temps

After S300/S400 or S400/S400 compounds:

Towing 32,000 lbs, 800+ HP: 950-1,050°F (225-325°F cooler)
MORE load, MORE power, yet dramatically cooler operation
This is why compounds dominate serious 5th gen builds

Why EGT control critical for latest 6.7L:

1,075 lb-ft factory torque = enormous fuel delivery even stock
High cylinder pressures at elevated EGTs stress head gasket severely
Turbo upgrade essential for safe power increases beyond 600 HP
Lower EGTs dramatically extend all component life

Safe EGT guidelines for 2019-2024 6.7:

Cruising: Under 975°F ideal
Towing: 975-1,125°F acceptable
Max short bursts: 1,225°F for passing (brief)
Danger zone: Sustained 1,275°F+ risks damage
