About Detroit Diesel

Detroit Diesel was born and bred to meet the American demand for diesel trucking in 1938, with none other than General Motors at the helm. After being born from the biggest of the Big Three, Detroit Diesel went on to create countless classic diesel parts ranging from engines to minor accessories. Despite the success of the brand, General Motors eventually sold Detroit Diesel to Daimler-Chrysler in 2000. As a part of Daimler-Chrysler, Detroit Diesel has access to the global resources and expertise of the world's foremost transportation company. It greatly benefits a lot of its customers. One year later, the brand decided to go beyond designing and manufacturing engines, simplifying its name to just Detroit®. Today, Detroit remains a part of Daimler Trucks North America, together with other major manufacturers, including Western Star Trucks, Freightliner Trucks, Freightliner Custom Chassis Corporation, and Thomas Built Buses. Since its inception, it has already built over 5 million engines, more than 1 million of which are still in operation worldwide. If your fleet still uses these engines, you'd be glad to know that the brand remains committed to serving you through its wide parts and distribution network found in over 800 locations in North America.

Detroit Axles

Equip your fleet with Detroit® axles for reliable precision and unmatched stability for the long haul. These maneuverable and versatile axles are made to fit into the tightest spots or haul up the steepest grades. There are three options available from this product category, which include the following:

Detroit® Front-Steer Axles - Machined and assembled in a state-of-the-art facility, the Detroit® front-steer axles are made to offer rugged strength in a lightweight package. They come in multiple ratings to meet your specific weight distribution needs. They also provide superior maneuverability with a 55-degree wheel cut. Equipped with needle bearings instead of bushings, these axles are guaranteed not to damage the kingpins.

Detroit® Single Rear Axles - With larger differentials and precision-machined gears, the Detroit® single rear axles mean more uptime, increased productivity, and reduced total cost of ownership. These are explicitly designed for higher torque applications, increased payload capacity, and quieter operation. They are made using the latest axle technology for improved efficiency and performance.

Detroit® Tandem Rear Axles - The tandem rear axles from Detroit® share the same features as the single rear axles. The only difference is that these axles feature an optional axle lubrication management (ALM) system, which helps reduce friction and parasitic loss by actively regulating the oil level at the ring gear and friction-loss optimized pinion bearings.

Detroit Transmissions

Rugged, reliable, and ready to work. These are the words that best describe Detroit’s transmissions, notably the DT12® vocational series. This series is available in two vocational models: the DT12®-V and DT12-VX, and is now available in the Western Star 49X. It also comes equipped with large, robust gears, which allow for increased input torque and gross combination weight (GCW). Other features include side PTO capability for increased application coverage, improved oil system design, and ease of operation for driver comfort.
