Axle performance plays a vital role in improving fuel economy, enhancing durability, and lowering emissions on any commercial vehicle. At Cummins, we strive to develop reliable and efficient technologies that reduce complexity while improving these outcomes. The Meritor Lube Management System (MLMSTM) embodies this philosophy. Designed to enhance axle efficiency, prolong component life, and reduce emissions, MLMS delivers measurable benefits for fleets without the need for pumps, electronics, or added complexity.

What is axle gearing?
Axle gearing plays a critical role in vehicle performance. It determines how efficiently engine power is delivered to the wheels, which directly impacts fuel efficiency, torque, acceleration, and the ability to climb grades. Selecting the right axle gearing can lead to lower fuel costs, improved drivability, and fewer maintenance issues throughout the vehicle’s life cycle.

At Cummins, we are committed to helping customers match the right axle gear ratio to each application for maximum performance and return on investment. As powertrain systems become more complex, proper axle gear ratio ensures that vehicles remain responsive, efficient, and reliable in real-world operating conditions.
