Hendrickson Launches ULTIMAAX™ Advanced Severe-Duty Rubber Suspension for International® Branded Truck

WOODRIDGE, Ill. (October 2018) — Hendrickson Truck Commercial Vehicle Systems officials announce the introduction of ULTIMAAX™, the next generation in severe-duty rubber suspensions, for International® branded Trucks in Mexico, Latin America and the Caribbean. ULTIMAAX represents Hendrickson’s latest product innovation in its 100-year history serving the medium- and heavy-duty trucking industry.

ULTIMAAX is designed specifically for severe-duty vocational markets with durability being its cornerstone feature. “This suspension has truly raised the bar for durability, making it the ultimate in severe-duty rubber suspension technology,” says Ashley Dudding, Director of Engineering for Hendrickson.
The ULTIMAAX system has been through more extreme testing than any product developed by Hendrickson to date, including running in some of the most severe applications in Mexico and throughout Latin America since 2013, receiving outstanding feedback on its performance and capabilities.

ULTIMAAX delivers excellent durability, enhanced stability, handling and ride quality even in the most severe-duty environments where vehicles encounter harsh and unexpected ground conditions. The integration of Hendrickson’s proven walking (equalizing) beam technology, with its patented progressive rate spring, provides a balance of loaded stability and unloaded ride quality even in the most rugged environments.

ULTIMAAX optimizes weight savings without sacrificing durability, resulting in a product that is hundreds of pounds lighter than competitive suspension systems for higher payloads. In addition, the system has very low maintenance requirements, resulting in lower suspension-related costs over the life of the vehicle.

Available initially in capacities of 46,000lbs through 52,000lbs on the International Workstar®, ULTIMAAX is approved for vocational and severe-duty applications. For additional information on ULTIMAAX, please contact Hendrickson Truck Commercial Vehicle Systems at 630-910-2800 or
