Reliable Drive Trains
Up to 19% Better Fuel Economy
Combining the best in American and European engineering, Detroit Diesel drive trains are the best of both worlds: ultra rugged and yet fuel efficient. Find the truck transmission and axles right for your business.
Our advanced AGS transmission can save you up to 19% on fuel economy. It's the smartest automated (not automatic) truck transmission on the road today.

Our innovative 6-speed manual truck transmissions deliver a more comfortable, easy-shifting driving experience.

Can a front axle system really save you money? You bet. Built with needle bearings for tighter tolerances, you get less tire wear, less maintenance, and maximum reliability.

Looking to control fuel costs? Start here. Our innovative single rear axles are significantly lighter than the competition for better fuel economy and maximum payload.

The heavy-duty advantages of an improved driveline angle, precision cut gears, and a larger differential make this tandem rear axle system the most robust on the Class 8 truck market.
“If the engine is the heart of a truck, the transmission is its soul.”
