Protecting Your Livelihood

Link offers a range of suspension solutions for trailer applications. From our experience with primary off-highway suspensions to our full lineup of suspension controls, Link is able to provide solutions where others have failed.

Link understands on- and off- highway vibration stress can result in damages to a trailer’s load and the trailer itself. Link offers fully integrated suspension solutions for trailers that will reduce stress on both the trailer and the driver. We provide several engineered leveling systems to give drivers added control over their trailer and its load, protecting the trailer, cab and payload from damaging conditions. Link also designs and manufactures trailer lift axles, custom military trailers, and severe-duty trailer suspensions for customers requiring maximum reliable performance in difficult environments.

Link recognizes that customers need specialty products to enhance the productivity of a trailer to save valuable time, which is why Link engineers products to address the critical needs of our customers and the industry.
