Enhance Your Installation, Performance and Uptime

Link Manufacturing’s family of self-steer auxiliary suspensions enhances the installation, performance and uptime of work trucks and heavy-duty vocational vehicles. Featuring Swift Mount Technology, Link’s self-steer auxiliary suspensions use patented interchangeable ride height brackets and integrated air kits to reduce installation time by 50-70%. Four sets of interchangeable brackets can be used to mount any current self-steer Link auxiliary suspension. Our Self-Steer lift axle is available in 8K, 10K, 13.5K (drum or disc brake option), and 20K capacities.

Swift Mount and Suspension Performance

To provide even greater ease of installation, the “stepped-edge” design helps the installer center the suspension on the frame, greatly reducing the time to achieve true alignment. The optional fender bracket attachments eliminate the need to remove the hub during installation.

The new 8K and 10K auxiliary suspensions incorporate heavy duty bearings and are engineered using proprietary brakes and drums. The 13.5K suspension is available with optional drum or disc brakes. Our new cast trailing arms provide increased durability while simplifying the suspension’s lifting geometry. A compact mounting envelope, combined with an optional integrated air control system, also saves valuable frame rail space.


Engineered to Link’s exacting standards for reliability and durability, all self-steer auxiliary suspensions are equipped with new rugged cast arms and Link-KOAT® migratory self-healing metal treatment to provide corrosion resistance and rust protection.
