COMPOSILITE® EXS 20

Lightweight 20K steerable lift axle truck suspension system

COMPOSILITE EXS20 - 20K Truck Steerable Lift Axle

COMPOSILITE EXS TRUCK is Hendrickson’s innovative next generation of steerable lift-axle suspension systems engineered for enhanced durability and performance. Several technological advancements enabled Hendrickson to take this concept from theory to the road. Inset lower beams help to optimize lateral stiffness and to eliminate the need for V-rods. Zero-torsion rubber bushings provide increased service life and lower cost of ownership with reduced down-time. The patented STEERTEK axle technology increases structural durability and incorporates bolt-on axle seats for easier serviceability and re-configuration, thereby lowering the cost of ownership. In addition, the more robust COMPOSILITE EXS has a stellar 7-year structural warranty.
