Mack Trucks Inc. now offers a new first-of-its-kind stability system – Mack Road Stability Advantage by Bendix (RSA) – for concrete customers.

The full electronic stability system is now available for mixer applications on the Mack Granite model, the top-selling heavy-duty Class 8 conventional straight truck.
“We’re very proud to be the first heavy-duty truck manufacturer to offer this technology to vocational customers,” said Steve Ginter, Mack vocational products marketing manager. “Concrete customer demand for stability protection is strong because mixers, in general, are recognized to have a high center of gravity and carry dynamic loads.”
Mack RSA uses the existing ABS wheel speed sensors, along with steering, yaw and lateral acceleration inputs, to deactivate the throttle and selectively apply the brakes in sharp curves, sudden lane changes, or obstacle avoidance maneuvers, reducing the potential of a rollover.
In conjunction with Bendix Commercial Vehicle Systems, Mack began offering full electronic stability technology on its highway vehicles late last year.
“Engineering this technology for tractors is more straight-forward,” said Tom Kelly, Mack vice president of marketing. “We’re committed to getting this technology in the hands of mixer and dump customers as soon as possible. We targeted mixers initially per customer demand. But we’re working very hard with our partner, Bendix, on other vocational applications as well, to make the technology available across the board in the very near future.”
