 WOODRIDGE, Ill. (March 2021) – Hendrickson Truck Commercial Vehicle Systems announced today that ULTIMAAX® advanced severe-duty rubber suspension in the 60,000 - pound capacity rating will be available on Miller Industries new Century® M100 Rotator and will be on display April 8-10th at the Tow Show in Orlando, Florida. Miller will be hosting a Street Party on April 9th, during the show, to display their trucks in action and give attendees an up-close and personal look. 
John L. Hawkins, Vice President, Heavy-Duty Products at Miller Industries stated, “In Miller’s Class 8 program, our demand for stability, ride height, suspension recovery, minimum lateral roll, and capacity is huge. With the upcoming introduction of Miller’s M100, we needed a suspension that offered a GVW rating higher than 52K while still delivering driver comfort. The ULTIMAAX 60K suspension is a perfect example of how Hendrickson listened to a need, worked with all parties to be responsive, and together, targeted the solution to meet the goal. And now we are seeing that teamwork come together with the introduction of the ULTIMAAX suspension on Miller’s M100 Rotator.”
“The Miller M100 Rotator on the Peterbilt 389 chassis marks the first new production vehicle in North America to feature the ULTIMAAX suspension at the 60,000 - pound capacity, and we are very excited to be able to offer a great suspension solution to a valued partner like Miller Industries,” stated Sean Whitfield, director of marketing for Hendrickson Truck Commercial Vehicle Systems.
