All anti-lock braking systems are not created equal. Our ABS outnumbers all others used by North American commercial vehicle operators. At Meritor WABCO, we've taken advanced technology and made it reliable and easy to service.

Different vehicle configurations and suspension systems may require different ABS configurations. That's why Meritor WABCO offers a complete range of systems—available in 4S/4M 6S/4M, and 6S/6M configurations. We provide the right fit for your operation depending on vehicle application, number of axles and type of suspension system. In addition, each ABS configuration is available with Automatic Traction Control (ATC) for improved traction.

The benefits of ABS include:

• Improved vehicle control under extreme road conditions
• Reduced downtime from accidents
• Lower cargo damage from reduced accidents
• Stabilized insurance costs

Whatever your needs, Meritor WABCO can provide the right ABS system for you.
