Meritor - Truck Equipment Atlas

Meritor is a commercial vehicle equipment brand associated with axles, drivelines, brakes, and related transportation components. Its products serve highway trucks, vocational vehicles, buses, trailers, and specialized equipment.

Meritor became part of Cummins in 2022. This page brings together its history, equipment categories, company information, and product profiles published on Truck Equipment Atlas.

History and Background

Meritor’s industrial heritage includes the automotive component operations of Rockwell International. In 1997, Rockwell spun off its automotive business, creating Meritor Automotive.

In 2000, Meritor Automotive and Arvin Industries merged to form ArvinMeritor. After divesting its light-vehicle business, the company returned to the Meritor name in 2011.

The business expanded its commercial vehicle capabilities through product development and acquisitions. Milestones included the 14X tandem axle, EX+ LS air disc brake, and additions to its specialized axle and electrification portfolio.

Cummins completed its acquisition of Meritor on August 3, 2022. The acquisition brought Meritor’s axle, brake, drivetrain, and electric powertrain capabilities into Cummins’ broader transportation equipment business.

What Meritor Manufactures and Supplies

Meritor-associated equipment supports several functions within commercial vehicle chassis and powertrain systems. Principal categories include:

Drive axles: Single, tandem, and specialized axle configurations.
Steer axles: Front axle equipment supporting vehicle weight and steering movement.
Electric powertrains: Integrated electric drive equipment for compatible commercial vehicles.
Drivelines: Driveshafts, universal joints, and related torque-transfer components.
Foundation brakes: Air disc brakes, S-cam drum brakes, and associated components.
Aftermarket equipment: Replacement and service components for supported axle, brake, and driveline applications.

Legacy Meritor WABCO Equipment

The Meritor WABCO name reflects a historical brand relationship. WABCO later became part of ZF, so this equipment’s current support resources should be identified separately from Cummins-Meritor axle and brake products.

Technology and Product Development

Meritor’s equipment development connects axle gearing, torque transfer, wheel-end braking, and vehicle application requirements. Its integration into Cummins brings these capabilities alongside engine and broader powertrain expertise.

The product range includes conventional mechanical axles and electric powertrain equipment. These systems require different approaches to packaging, gearing, controls, and vehicle integration.

Permalube RPL drivelines use permanently lubricated universal joints, while XTended Lube MXL equipment follows an extended-lubrication approach. Inspection and service requirements remain specific to the complete driveline assembly.

Features and ratings vary across the product range. Axles, brakes, and drivelines should be evaluated as parts of a complete vehicle configuration rather than selected by brand name alone.
