100% Off-Highway Rating

Off-Highway vehicles such as logging, mining, heavy haul, oil tankers, and end dump trailers operate in extreme terrain conditions. Unlike other manufacturers, Link’s chassis suspensions are tested and rated for 100% off-highway applications. They are designed to provide increased hauling capacity, greater stability and a better quality ride while increasing productivity by allowing drivers to maintain their speeds on off-highway terrain with a full or empty load. Cabmate® can also be spec’d as an option on these vehicles, providing an even better ride for the driver by reducing backslap, vibrations, and back stress.
