CONNEX ST Steerable Suspension System

CONNEX™ ST combines Hendrickson’s proven HT230 Top Mount and HT250 Underslung suspensions with its innovative steer axle technology. Complemented by the proven UBL™ axle lift system, CONNEX ST delivers a compliant solution that offers maximised operating efficiency.
These suspensions offer improved trailer manoeuvrability, reduced tyre wear and lower cost of life of a self-steer axle, along with the benefits of optional HXL7® extended long-life wheel end system and TIREMAAX™ PRO. 

TIREMAAX PRO advanced tyre inflation system provides constant active inflation, relieving and equalising of tyre pressures and HXL7 Hendrickson Extended-Life wheel-end system features a 5-Year 1.2 million kilometre on-highway warranty.

The CONNEX ST steerable suspension helps operators meet applicable regulatory needs for steerable axle applications, including Australian National Heavy Vehicle Regulator (NHVR) and Performance Based Standards (PBS).It is designed to be compatible with trailers fitted with both top mount and low ride drum-brake INTRAAX® suspensions. It provides fleets with the peace of mind by having a complete Hendrickson solution throughout their trailers.
