Everything We Know About the 2024 Duramax L5P 6.6L Engine

Gale Banks cracks open a new 2024 Duramax 6.6-liter diesel engine and compares the parts side-by-side with a 2023 model. With this inside look, Gale finds upgrades to the 2024 L5P Gen 2 that you won't see on a spec sheet, including a new piston design, fuel rail enhancements, a new high-pressure fuel pump, and an upgraded turbo. All of these new parts look pretty durable, but will they translate to more power?
