Hendrickson Launches ULTIMAAX® Advanced Severe-Duty Rubber Suspension and STEERTEK NXT Fabricated Front Steer Axle for the Fire and Rescue Market 

WOODRIDGE, Ill. – Hendrickson Fire and Rescue officials announce the introduction of ULTIMAAX®, the next generation in rear tandem rubber suspensions, along with STEERTEK NXT fabricated front steer axle platform.
ULTIMAAX was designed specifically for severe-duty applications, tailored to the fire and rescue market. With durability being its cornerstone feature, “ULTIMAAX has truly raised the bar for durability, making it the ultimate in rubber suspension technology,” says Chris Batsch, director of Fire and Rescue at Hendrickson.  

In addition to its excellent durability, ULTIMAAX® delivers enhanced stability, handling and ride quality. The integration of Hendrickson’s proven walking (equalizing) beam technology with its patented progressive load spring provides a balance of loaded stability and unloaded ride quality.  As load increases, the progressive load spring engages and the ride and stability characteristics of the suspension change to meet the application’s needs without an abrupt change in ride quality.  This superior ride translates to reduced road shock and vibration to the vehicle, which contributes to longer service life of the cab, chassis and body equipment.
 ULTIMAAX optimizes weight without sacrificing durability, resulting in a product that is hundreds of pounds lighter than competitive suspension systems and saving weight for other crucial components.  Available in capacities of 48,000 to 65,000 pounds, ULTIMAAX is the high capacity rubber suspension solution for the fire and rescue market.

STEERTEK NXT is now available in capacities from 16,000 to 24,000 pounds, expanding Hendrickson’s portfolio of front steer axle solutions.  While the Hendrickson axle platform is new to the fire and rescue market, Hendrickson’s STEERTEK fabricated axle technology has been proven in on-highway applications for 15 years.  Hendrickson’s proprietary manufacturing process achieves durability, rigid strength and weight efficiency.  Compared with traditional forged I-beam axles, STEERTEK NXT’s box-shaped cross section more effectively resists horizontal, vertical and twisting forces and provides up to 40 pounds of weight savings.  The innovative design easily integrates with a variety of suspension configurations, including integrated solutions with Hendrickson bushings and springs for optimized system performance.
