Link’s 20K self-steer suspension incorporates technological and component upgrades already available in the company’s lighter-capacity suspensions. The suspensions feature Swift Mount technology, allowing installation to be completed in as little as two hours. The Swift Mount interchangeable ride height brackets incorporate improvements in the way the frame brackets attach to the suspension hanger. The brackets can be used to mount any Link suspension. Rear air spring brackets are compatible with wide flange frame rails by having the air fittings oriented to the outside. The air fittings can also be repositioned to the inside if desired. 800-248-3057; www.linkmfg.com.
