The LLY Duramax powered 2004.5 to 2005 Chevy Silverado HD and GMC Sierra HD trucks. It was the first Duramax with a variable geometry turbo and EGR, which helps it spool faster than the LB7.

LLY Duramax FAQ

What is different about the LLY versus the LB7?

The LLY added a variable geometry turbo and EGR for faster spool and lower emissions.

Are LLY trucks known for overheating?

Some early LLY trucks ran hotter under load. Upgraded cooling parts are a common fix for trucks that tow heavy.
