What Turbo Is on a 2017–2019 6.7 Powerstroke? Specs, Years & Fitment
Ford has put four different turbochargers on the 6.7L Power Stroke since 2011, and parts for one generation rarely fit another. If you are replacing or upgrading the turbo on a 2017, 2018 or 2019 Super Duty, this is what is under the cowl and what to check before you order.
Quick answer: 2017–2019 6.7 Powerstroke pickups use a Garrett GT37 family variable geometry turbo (Garrett model AVNT3788) with a single 61mm (2.40") inducer compressor wheel, a journal bearing cartridge, no wastegate and oil-actuated vanes. Cab and chassis trucks use a different version.
6.7 Powerstroke Turbo by Model Year
| Years | Factory turbo | Key traits |
|---|---|---|
| 2011–2014 | Garrett GT32 SST | Dual-sided compressor wheel, ceramic ball bearing, wastegate, VGT. The generation with the reputation for turbo failures. |
| 2015–2016 | Garrett GT37 (AVNT3788) | Single 61mm compressor, larger turbine, journal bearing, no wastegate, VGT. |
| 2017–2019 | Garrett GT37 (AVNT3788), updated | Same family as 2015–2016, revised for the 2017 Super Duty with an updated pedestal. Ford superseded later service turbos back to 2015–2016 trucks. |
| 2020 and later | Revised Garrett VGT | Electronic vane actuator and different hardware. Not interchangeable with 2017–2019. |
Factory Power by Year
- 2017: 440 HP and 925 lb-ft
- 2018–2019: 450 HP and 935 lb-ft
The same turbo family covers both ratings. The difference is calibration, which is part of why the factory turbo has limited headroom left once a 2018–2019 truck is tuned.
How the 2017–2019 Turbo Works
The GT37 has no wastegate. Instead, a ring of movable vanes sits around the turbine wheel. Closing the vanes speeds up exhaust gas into the wheel for quick spool at low engine speed. Opening them lets more exhaust through at high load so the turbo does not overspeed. On 2011–2019 trucks those vanes are moved by engine oil, routed through a VGT control valve that the PCM commands. Partly closing the vanes is also how the factory exhaust brake builds back pressure.
Because the turbo sits in the engine valley, it lives in a lot of heat. That matters for both reliability and upgrade choices, and is covered in 6.7 Powerstroke VGT Turbo Problems.
Pickup vs Cab and Chassis
Ford fitted 2017–2019 cab and chassis trucks with a different factory turbo from F-250, F-350 and F-450 pickups. They look similar, but replacement turbos are listed separately for each, and a pickup turbo should not be assumed to fit a chassis cab. When buying a stock replacement, match the turbo to your body style. The TNT 63.5/62 drop-in is built to fit both.
What This Means When You Upgrade
- Know your year range. A turbo built for 2017–2019 is not automatically a fit for 2015–2016, and never for 2011–2014 or 2020+.
- Know your body style. Stock pickup and cab and chassis turbos are different parts, so check that any upgrade covers your truck.
- Decide whether you need the vanes. A drop-in VGT keeps factory-style spool and exhaust brake function. A fixed geometry conversion gives that up. See VGT vs Non-VGT Turbo for the 6.7 Powerstroke.
The True North Turbos 63.5/62 drop-in is built for 2017–2019 6.7 Powerstroke F-250, F-350, F-450 and F-550 trucks, pickup or cab and chassis (not 2015–2016). It keeps factory VGT control and the exhaust brake, with a 63.5mm (2.50") 6+6 compressor and a 10-blade mixed-flow turbine.

Frequently Asked Questions
What size turbo is on a 2017 6.7 Powerstroke?
A Garrett GT37 family VGT with a single compressor wheel measuring 61mm (2.40") at the inducer.
Does the 2017–2019 6.7 Powerstroke turbo have a wastegate?
No. Ford removed the wastegate when it moved to the GT37 in 2015. Boost is controlled entirely by the variable vanes.
Is the 2017–2019 turbo the same as the 2015–2016 turbo?
It is the same GT37 family, but the 2017–2019 version was updated for the 2017 Super Duty, including the pedestal. Do not assume a 2017–2019 part fits a 2015–2016 truck without confirming.
Is the 6.7 Powerstroke a twin turbo?
No. Every 6.7 Powerstroke uses a single turbo. The 2011–2014 GT32 had a double-sided compressor wheel, which is where the twin-turbo confusion comes from.
