Overview
American Axle & Manufacturing Holdings, Inc. is an American automotive driveline supplier producing axles, driveshafts, and related components.
History
American Axle & Manufacturing was formed in 1994 as an independent automotive supplier built around axle and related manufacturing operations that had been associated with General Motors. The formation separated these activities from their previous captive-manufacturer setting and created a standalone company focused on supplying driveline components to vehicle manufacturers. During its development, AAM expanded from its original axle manufacturing base into a broader driveline and metal-forming supplier. Its product scope came to include axle assemblies, driveshafts, differentials, transfer cases and other systems used to distribute torque to vehicle wheels. The company also developed capabilities in forging, casting and precision metal forming, allowing it to supply structural and mechanical components in addition to complete drivetrain systems. AAM's traditional market has included light trucks, sport-utility vehicles, passenger vehicles and commercial applications. Its products support several vehicle architectures, including rear-wheel drive, four-wheel drive and all-wheel drive. As a Tier 1 supplier, AAM generally works directly with automakers on product design, engineering validation, manufacturing and program delivery. The company therefore operates behind the vehicle brands that consumers see, even though its components can be integral to a vehicle's performance, durability and power-transfer characteristics. The automotive industry's shift toward hybrid and battery-electric propulsion has influenced AAM's technology direction. Electrified vehicles require different combinations of gears, shafts, differentials, reduction mechanisms and integrated drive units. AAM has consequently described its business as serving electric, hybrid and internal-combustion vehicles, rather than limiting its identity to conventional axle production. Electric-drive units and related technologies have become part of its stated mobility portfolio while conventional driveline products continue to support many vehicles in production. AAM's international operations reflect the global structure of vehicle manufacturing. Its customers and programs require regional engineering, production and supply-chain capabilities, and the company competes on scale, technical expertise, quality, cost and the ability to launch complex vehicle programs. Its business remains exposed to the cyclical nature of automotive production, customer concentration, raw-material and energy costs, labor availability, logistics conditions and the timing of new vehicle programs. The company is headquartered in Detroit, Michigan, and trades publicly in the United States under the ticker AXL. Its current corporate identity emphasizes the combination of driveline and metal-forming technologies and a role in the broader automotive and mobility supply chain. No separate consumer product brand should be inferred from the AAM name: the principal subject is the corporate supplier American Axle & Manufacturing.

Company established
[1]American Axle & Manufacturing was established as an independent automotive supplier through the acquisition and consolidation of selected axle-related operations formerly associated with General Motors.
Expansion into broader driveline and metal-forming technologies
[1]AAM broadened its stated capabilities beyond conventional axle production to include driveline systems, electric-drive technologies and metal-forming products for automotive and mobility applications.
Products and positioning
AAM positions itself as a global Tier 1 automotive and mobility supplier combining driveline engineering with metal-forming expertise. Its portfolio is intended to serve internal-combustion, hybrid and electric vehicles, with particular relevance to trucks, sport-utility vehicles and other platforms requiring robust power-transfer systems.
Driveline
Axle systems
AAM designs and manufactures axle systems and assemblies for light vehicles and other automotive applications. These systems form a core part of the vehicle power path, supporting torque delivery, wheel speed differentiation and the structural demands of rear-wheel-drive, all-wheel-drive and four-wheel-drive platforms. Product configurations vary by vehicle architecture, load requirement and customer program.
Driveline
Driveshafts and propeller shafts
AAM's driveshaft products transfer rotational power between major drivetrain components. They are engineered for the packaging, torque, vibration and durability requirements of different vehicle platforms. Driveshafts may be used in conventional, hybrid and other driveline layouts, depending on the vehicle's propulsion and power-transfer architecture.
Driveline
Differentials and transfer cases
Differentials allow driven wheels to rotate at different speeds while transmitting torque, while transfer cases distribute power across drivetrain paths in four-wheel-drive and related systems. AAM supplies these technologies as part of its broader driveline portfolio for vehicles requiring traction management, off-road capability or multi-axle power distribution.
Electrified mobility
Electric-drive units
AAM develops electric-drive and related propulsion technologies for electrified vehicles. These products adapt the company's power-transfer expertise to electric motors and high-torque operating conditions. They are intended to support battery-electric and hybrid vehicle architectures alongside the company's established internal-combustion driveline products.
Metal forming
Metal-forming products
AAM's metal-forming activities include precision-manufactured automotive components produced through forming and related processes. These capabilities complement its driveline business by supporting the production of structural and mechanical parts with demanding strength, dimensional and durability requirements.
