COMPOSILITE EXS Trailer (Weld-on & Bolt-On) – the next generation of lighter yet more durable steerable lift axle suspension systems for trailer applications. A number of technological advancements enabled Hendrickson to take this concept from theory to the road. Inset lower beams help optimize lateral stiffness and eliminates the need for V-rods; zero-torsion rubber bushings provides increased bushing life and lower cost of ownership with less down-time; patented STEERTEK axle technology increases structural durability and bolt-on axle seats make for easier serviceability, while adding to lower cost of ownership. In addition, the upper aluminum beams help reduce weight without sacrificing durability. A stellar 7-year structural warranty accompanies the COMPOSILITE EXS. Available in 13K and 20K capacities.
