The 6.6L Duramax LML hit the market in 2011 and stuck around through 2016 after which it was replaced by the L5P. The LML produced a solid 397hp and 765lb-ft. of torque. While the LML’s torque output fell slightly short of the 6.7 Powerstroke and 6.7 Cummins, the engine produced just about as much power…
The 6.6L Duramax LML was released in 2011 and produced through 2016. Producing 397hp and 765lb-ft. of torque, the LML delivered solid power and was a strong competitor to Ford and Cummins 6.7L diesel engines of the time. While the LML’s power is just about as much as anyone would need, there are still some…
The Duramax LB7 was the first engine released under the new 6.6L Duramax platform. The LB7 was considered a strong and stout engine for the time, producing 235hp and 500lb-ft. of torque which was upgraded to 300hp and 520lb-ft. of torque in 2004. However, the LB7 produces about half the power as the diesels of…
The Duramax L5P was introduced in 2017 as a replacement for the LML. Featured in the Silverado and Sierra HD work trucks (2500HD/3500HD), the L5P uses the same 6.6L turbo-diesel powerplant that has been in use since the LB7 since 2001. While the engine uses the same 6.6L design, many major engine components were completely…
Following the short lived LMM engine, the Duramax LML was introduced in 2011. Featured in the same 2500 and 3500 HD work trucks, the LML sported the same 6.6L turbo-diesel design that Chevy diesel trucks have been using since 2001. However, the LML was actually the biggest overhaul Duramax had done to the 6.6, claiming…
Duramax P2563 – Vane Control Position Sensor When your Duramax begins throwing a P2563 code, a scan tool will read ‘Turbocharger Vane Control Position Sensor Performance‘. The vane position sensor controls the unison ring and turbo vanes located within the Duramax’s Garrett turbocharger. P2563 and P003A are common engine codes amongst 2004.5 to 2016 Duramax…
Duramax LBZ Guide to Performance & Cold Air Intakes If you had the 8.1 Vortec engine in your truck instead of a Duramax, I’d probably be telling you an intake is a waste of money. However, for turbo-diesel engines it’s one of the first mods we recommend for people just getting started. Outside of an…
Following the LBZ being phased out in mid-2007, the LMM Duramax took its place as Chevy & GMC’s diesel truck engine. Following the same 6.6L powerplant, the LMM was introduced due to continuously increasing diesel emissions regulations and lasted until 2010 when it was phased out for the LML. Compared to the LBZ, the LMM…
Hitting Chevy and GMC trucks starting in 2004, the LLY Duramax is the 2nd version of the 6.6L V8 Duramax. In order to meet stricter emissions regulations, the LLY replaced the LB7 engine and was the first Duramax to use EGR emissions technology. In addition to EGR, the LLY switched over to variable-vane turbocharger (VVT)…
Introduced in 2001, the LB7 is the OG 6.6L Duramax. This engine is the base platform that today’s 6.6L L5P Duramax is built off of. Spanning six different variations and nearly 20 years of production, the LB7 has certainly proved to be a reliable and durable platform. 2001 year models were pushing 235hp and 500lb-ft….
The LBZ Duramax is, still today, the favorite Duramax of diesel enthusiasts. Produced from 2006 to 2007, the shortest production Duramax, the LBZ produced 360hp and 650lb-ft. of torque. To support the power increase over the LLY model, the block was improved, the rods were forged, and the engine was overall built to withstand more…
