The 2017 Duramax model year marked a significant leap forward in GM’s diesel lineup. Released in 2017, this engine came out strong with 445 horsepower, establishing itself as a class leader. Despite rumors of a potential displacement increase, GM stuck with the 6.6L configuration, focusing instead on overhauling key engine components and boosting overall durability.

The 2017 - 2019 Duramax engine received a number of critical upgrades, from a stronger block and crankshaft to reinforced rods and remelted pistons. The fuel system was redesigned for more efficient delivery, while the camshaft profile was adjusted for optimized performance.

2017 to 2019 Chevy and GMC 6.6L L5P Duramax FAQ
What factory upgrades make the 2017 to 2019 L5P Duramax stronger than earlier models?
This generation introduced a reinforced engine block, stronger crankshaft and rods, updated pistons, improved camshaft design, and a redesigned fuel system built to support higher power levels and long term durability.
Is the functional hood scoop on 2017 to 2019 Duramax trucks beneficial?
Yes, the factory hood scoop increases airflow into the engine bay, helping reduce intake air temperatures and supporting consistent performance during towing and heavy use.
What performance upgrades provide the best gains for a stock 2017 to 2019 L5P Duramax?
Intake airflow improvements, exhaust upgrades, and tuning options deliver noticeable gains in throttle response, torque delivery, and overall drivability without compromising reliability.
Can injector upgrades improve performance on a 2017 to 2019 Duramax?
Injector upgrades can restore lost efficiency over time and support higher fuel demands on tuned trucks, improving power output and smooth operation.
Is the Allison transmission in 2017 to 2019 Duramax trucks capable of handling added power?
The updated Allison 1000 transmission was designed to handle increased factory power and can support moderate performance upgrades when paired with proper tuning and maintenance.
Can a modified 2017 to 2019 L5P Duramax still serve as a reliable daily driver?
Yes, many owners daily drive modified L5P Duramax trucks. Balanced upgrades and routine maintenance help preserve comfort, drivability, and long term reliability.
I have an EFILive AutoCal for my earlier Duramax. Can that same tuner work on my L5P Duramax?
In short, no, EFILive has not yet updated their files to allow L5P tuning to be loaded into their AutoCal tuning devices.
Will a DPF (Diesel Particulate Filter) back system provide more sound to my truck?
Generally speaking no, the emissions equipment upstream will still act as a muffler. However, that doesn't mean installation will not help in other areas by improving exhaust flow. While minor, the benefits are noticeable, plus an aftermarket exhaust looks way better than the stock exhaust.
I'm looking at an exhaust kit on your website, but it doesn't state which cab and bed configuration it fits, will this fit my application?
In most cases, unless it is specifically stated as fitting a certain configuration, all exhaust kits on our website will fit all cab and bed lengths. Further, most kits will not fit cab and chassis applications unless otherwise noted.
I'm looking at this 5" (or other) exhaust kit, but my truck only has a 4" exhaust now. Does this 5" exhaust include an adapter / reducer?
Yes, the exhaust systems we sell will adapt down to fit the application at the designated starting point (turbo back, cat back, DPF back, etc.) for a hassle free installation.
What are EGT's?
EGT stands for Exhaust Gas Temperature, which is the temperature of the exhaust leaving your engine. This measurement is typically measured before the turbo to ensure you are not overheating components. For most applications, we recommend not exceeding 1300 degrees.
Will the products you offer void my warranty?
Some parts may void your warranty and some may not. We recommend researching the Magnuson-Moss Warranty Act that specifically protects consumers when choosing to install aftermarket components on their vehicles, as well as consulting with your local dealer.
