Heavy-Duty Performance

The Air Link® Tandem Drive Suspension is a unique combination of air and walking beam technology. It delivers everything you demand in a heavy-duty suspension - high roll stability, low maintenance and a smooth ride. The unique design also ensures maximum traction and load equalization throughout articulation.

Air Link comes as an option on Mack, Volvo, Kenworth and Navistar vocational chassis. Air Link is available in standard 46K, 52K, 60K & 85K configurations. The suspension can also be retrofitted as a bolt on aftermarket package for older vocational trucks.

Air Link exceeds industry requirements for heavy duty suspension applications. It has been proven to lower operating and maintenance costs, reduce damage to chassis and mounted equipment, diminish vibrations, lengthen tire life, extend suspension and bushing life, and reduce downtime. Air Link is available for capacities ranging from 46,000 lbs. to 85,000 lbs.

Features

  • Air Link - Ride Height Brackets

    Mounting Bracket System

    The mounting is flexible with engineered variants to be bolted to C-Channel frame rails or welded to box frame designs. For bolt on suspensions, the pattern and size of bolts can be adjusted to suit OEM grid patterns and preferred hardware.

  • Air Link - Walking Beams

    Rugged Walking Beams

    The rugged beam construction evenly distributes the load for maximum traction and maintained alignment. The walking beams are designed without bearings and seals for minimal maintenance and wear points.

  • Air Link - High Volume Air Springs

    High Volume Air Springs

    High volume air springs offer low natural frequency for optimum ride qualities laden or unladen. An internal rubber jounce stop supports the vehicle during airless operation (frame will drop 2”).

  • Air Link - Dual Height Control Valves

    Dual Height Control Valves

    Dual height control valves maintain optimum vehicle ride height independent of load. Both control valves level the vehicle side-to-side. Each valve controls one side of the suspension to reduce lean with uneven cargo.

  • Air Link - Shock Absorbers

    Shock Absorbers

    Each set of shock absorbers are tuned for optimal ride characteristics, enabling the best ride possible, regardless of road conditions. Shock absorbers dampen the suspension over uneven terrain to enhance driver comfort.

  • Air Link - Polyurethane Bushing

    Low Maintenance Bushings

    Heavy duty bushings provide a longer service life and minimal maintenance. The bushings does not require grease and the bar pin end bushing shims allow for easy alignment.

  • Air Link - Axle Compatibility

    Axle Compatibility

    Compatible with most common drive axles including Dana, Meritor, Mack, and others. The suspension comes with a variety of axle connections including bar pin, through-pin, and alignment bushings.

  • Air Link - 100% Off-Highway Rating

    100% Off-Highway Rating

    Air Link suits a variety of heavy-duty applications. The unique combination of air over walking beam design delivers high stability and vertical stiffness to create a stable off-highway suspension.

Testimonials

“We only had to engage 6-wheel drive 1-2 per year because of how well the Air Link transfers the weight to the ground and makes maintaining traction significantly easier.” Dan Smith VP & Product Manager
“Link determined the root cause of the problem and supported the installation of the solution. Other suspension providers offered air suspensions or walking beam suspensions, but Air Link provided a combination of the two that we needed.” Jason Schafer General Manager
“The key benefit of the Air Link is the walking beam does the function of load equalization and the air bags provide the cushion for a superior ride.” Andrew Harman Project Engineer
