Link Mfg.’s 85K Air Link Tandem Drive Chassis Suspension, originally designed for the U.S. military, has been optimized for heavy vocational commercial applications.

The suspension’s high-volume, low-frequency air springs help deliver a smooth and comfortable ride whether a truck is loaded or empty, the company says. Dual height-control valves maintain the proper ride height and a level vehicle, maximizing roll stability regardless of the cargo’s weight and balance, it adds.

Its air-over-walking-beam design can even continue to function even if an air spring is lost.

The suspension is 100% off-highway rated, and no adjustments are required once a wheel alignment is set.

The end result triples the roll stability of other vocational air-ride suspensions, the company adds, noting that the Air Link rides four times smoother than a conventional spring pack and 10 times smoother than a rubber block suspension.

Like the company’s other suspensions, it is treated with a Link-Koat migratory self-healing metal treatment to protect against corrosion and rust, even when surfaces are exposed to factors from excess abrasion to harsh chemicals.

The 85K Air Link Tandem Drive Chassis Suspension comes with an extended three-year warranty.
