Heavy-Duty Performance

The Air Link® Tandem Drive Suspension is a unique combination of air spring 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.

Air Link® TD comes as an option on Mack, Volvo and Navistar vocational chassis’ in standard 46k or 52k configurations. For heavier vocational applications such as cranes, fire trucks and logging, the Air Link® TD can be retrofitted with up to 85k capacities.

The distinctive Air Link® TD design provides superior traction when the load is full, without the bone-jarring ride when empty. Originally constructed to meet the demands of the logging industry, Air Link® TD is the only air spring suspension designed specifically for the builders or manufacturers of fire and rescue, logging, refuse, heavy haul, redi-mix, cranes, military, and any other severe service on/off highway vehicles.

Air Link® TD 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® TD is available for capacities ranging from 46,000 lbs. to 85,000 lbs.

Features

  • Web Air Link Bracket

    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.

  • Web 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.

  • Web Air Link Air Bags

    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”).

  • Web Air Link Control Valve 22

    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 delivering high roll stability. Each valve controls one side of the suspension to reduce lean with uneven cargo.

  • Web Air Link Shock Absorber

    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.

  • Web Air Link Bushing

    Polyurethane Bushings

    Polyurethane bushings provide longer service life and minimal maintenance compared to rubber bushings. Polyurethane does not require grease and the bar pin end bushing shims allow for alignment.

  • Web Air Link Axles

    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.

  • Web Air Link 100

    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.
