85K Air Link Tandem Drive, designed for US military, now commercially available for heavy vocational applications

Link Mfg says its 85K Air Link Tandem Drive Chassis Suspension now is commercially available for select makes and models.

Originally designed to meet the demands of the US military, the recently revealed 85K Air Link is optimized for heavy vocational commercial applications.

As North America’s highest-capacity air spring suspension, Link’s 85K Air Link Tandem Drive Chassis Suspension is designed with large, high-volume, low-frequency air springs that enable occupants to experience a consistently smooth and comfortable ride whether their vehicle is under load or empty, Link maintained. Dual height-control valves ensure that proper ride height and vehicle leveling are maintained, maximizing roll stability regardless of the weight and balance of a vehicle’s cargo.

Link’s air-over-walking-beam technology originally was designed to cope with extreme payloads and the rigors of harsh off-highway defense applications. Vastly superior to heavy-duty leaf spring, rubber block walking beam, two-spring “six-rod” and trailing arm suspensions, the 85K Air Link Tandem Drive Chassis Suspension provides a smooth, comfortable, uncompromising ride, Link claimed.

“Link’s 85K Air Link Tandem Drive Chassis Suspension has been optimized for select heavy vocational axles and will now deliver Link’s legendary ride quality at the highest capacity for any air spring suspension in North America,” said Neil Mardell, manager of defense programs and heavy vocational products for Link. “Not only is our 85K the highest-capacity tandem air spring suspension around, but because of its air-over-walking-beam design, it’s also one of the most resilient, able to continue functioning even if a loss of an air spring were to occur.”

The system’s ability to equally distribute weight, its high roll stability and its tractive superiority make operating on challenging off-highway terrain safer, more comfortable and ultimately more controlled, the company added. Like all Air Link suspensions, the 85K is 100% off-highway rated, designed to thrive in punishing off-highway environments, and once wheel alignment is set on an Air Link, no future adjustments are required.

“With three times more roll stability than any other vocational air-ride suspension, the Air Link rides four times smoother than a conventional spring pack and 10 times smoother than a rubber block suspension,” Mardell said. “The Air Link also offers users all the advantages of a combined air spring and walking beam suspension without all the downsides of more primitive steel or rubber walking beam suspensions.”

All Air Link suspensions are treated with Link’s exclusive Link-KOAT migratory self-healing metal treatment. Link-KOAT provides corrosion resistance and rust protection, even when surfaces are exposed to excessive abrasion, harsh chemicals and other severe-duty environmental factors. The 85K Air Link Tandem Drive Chassis Suspension includes an extended three-year warranty.

“Our 85K has been engineered to seamlessly interface with tier-one online installation processes,” Mardell said. “The Air Link 85K has served its time in the military and is ready to do super-heavy duty in the commercial sector.”
