Gale Banks inspects a new 2024 Duramax 6.6L turbo diesel engine and compares the parts side-by-side with a 2023 model; data you won't find on a spec sheet. Available in the '24 Chevy Silverado and GMC Sierra, the engine boasts 470hp / 975lb-ft, up from the previous generation's 445/910. Improvements to the engine include a new turbo, pistons with tapered bowl, cylinder heads with improved cooling jackets, higher-flow injectors for greater fuel injection pressure, fuel rails to handle the increased pressure, improvements to the glow plugs, improved engine braking thanks to a more powerful turbo vane actuator and upgraded valve springs, along with the latest generation Engine Control Module with new Global B architecture.

All of these new parts look seriously durable, but will they translate to more power? We already have a truck on the dyno. Stay tuned!

Banks prefers AMSOIL, the leader in synthetics.
