General Motors launched the Duramax engine in 2000, and it was the innovation the company needed to secure one of the top spots in the Diesel engine market. However, the company soon realized that it must constantly develop the engine to remain competitive. The first significant attempt to improve the first-generation Duramax engine gave birth…
In our 5 Best Duramax L5P Mods guide, we covered downpipes and mentioned them as our favorite exhaust upgrade. While a larger DPF-back exhaust system will provide solid sound gains, the biggest power gains within the exhaust actually come from upgrading the downpipe. Additionally, there are a number of ancillary benefits like lower EGTs and…
With the same displacement but different fuel types, the 6.6L gas L8T and the 6.6L Duramax diesel L5P engines certainly make a name for themselves when it comes to pulling their weight (and then some). Choosing between them, however, can be a much harder task. If you’re not sure which 6.6L V8 motor to choose…
The 6.5L Detroit Diesel engine was introduced in 1992 as the new and improved version of the 6.2L Diesel engine. Detroit Diesel designed the engine for General Motors, and it was the second collaboration between the pair, following the earlier 6.2L Detroit Diesel engine. While most of the 6.5L engines were sold with a turbocharger…
When it comes to powering your Chevrolet pickup truck, deciding between the available engine options can be a challenge. It’s not so much about displacement, but more a question of capability and, like many things automotive, what all can go wrong (and how much it will cost you). To help you decide between the 3.0L…

It was available in every application of square bodies from 1982 to 1991. The engine had two versions — the C and J code. The C code was a lighter-duty…
The 2.8L Duramax has been around since 2012 before it was eventually introduced into the U.S market. The engine was designed specifically for truck use but has been extended to vans. It features new technologies to deliver power and fuel efficiency. Before it was released in North America in 2016, the engine was upgraded to…
General Motors designed the 3.0L Duramax for use in their full-size half-ton trucks and SUVs. It was created as an alternative to the 6.6L Duramax which is far too big for the half-ton 1500 trucks. The engine was a collaboration between GM and Opel and was introduced as an option in the 2019 Chevrolet Silverado 1500…
Predecessor to the LML and successor to the LBZ, the LMM Duramax was launched mid-2007 and produced until 2010. One of the major changes to the new LMM was the DPF system which had a big impact on fuel economy. Despite the new restrictive exhaust equipment, power output was increased to 365hp and 660lb-ft. of…
The Duramax L5P is GM’s latest diesel in the 6.6L Duramax family. This means it is also loaded with every single diesel emissions system you can imagine. The L5P has selective cat reduction, diesel exhaust fluid, diesel particulate filter, diesel oxidation cat, and exhaust gas recirculation. While these emissions systems are great for reducing emissions,…
GM replaced the Duramax LMM in 2011 with the LML in part due to emissions requirements. One of the new features of the LML was the addition of he SCR system in conjunction with DEF fluid, which GM claims reduced emissions levels by over 50 percent. However many early model LML’s experienced SCR and DEF…
Released in 2017, the 6.6L Duramax L5P is the latest Chevy & GMC turbo-diesel engine. The L5P produces 445hp and 910lb-ft. of torque from the factory. When dyno’d the L5P produces about 400whp and 850wtq. You can’t ask for much more power from the factory. However, for those who are looking for some extra power…
