The Stability You Need. The Ride You Want.

The SWB (Spring Walking Beam) tandem steer suspension provides the added carrying capacity required in today’s heavy trucking industry. The suspension dynamically load equalizes through its spring over walking beam design. The innovative combination ensures proper axle tracking and weight distribution by minimizing possible overload scenarios.

The 40K SWB tandem steer suspension was specifically designed to reduce axle stress, suspension weight and maintenance costs. The engineered design blends the rugged durability and weight distribution of a walking beam with the simplicity of a spring suspension. The suspension is equipped to use common spring pins and wear parts for simple inspection, maintenance and replacement. The straightforward components largely reduce installation time as well as preventive maintenance.

Overall, drivers will appreciate the improved ride that the SWB offers. The spring over walking beam design isolates the chassis from road forces as well as less wear and tear on the vehicle. The SWB tandem steer suspension comes standard on many major North American cranes, and is available for heavy truck applications at a cost comparable to a conventional leaf spring twin steer.


  • Web Wheel Alignment

    Improve Vehicle Wheel Alignment

    Proprietary end pin design allow five points of adjustment and lock in wheel alignment to help simplify maintenance and extend service life.

  • Web Walking Beams

    Ensure Even Load Distribution

    The walking beam design will ensure maximum ground clearance and even load distribution between the steer axles through entire range of articulation.

  • Web Grease Points

    Reduce Maintenance

    The SWB has only two grease points (compared to 10 on a conventional 4 spring suspension) therefore reducing maintenance time and effort.

  • Web Bushings

    Increase Bushing Durability

    Designed with Polyurethane bushings at main suspension connections for reduced maintenance, increased durability, and eliminate lubrication requirements.

  • Web Ride Shock 2

    Heavy Duty Shock Absorbers

    Select air springs are tuned for the optimal ride characteristics, enhance driver comfort, and are protected for durability.

  • Web Lightweight

    Lightweight Suspension Design

    The straightforward design of the SWB weighs approximately 1755 lbs. This translates into a weight reduction of 10%-20% from typical OEM four-spring suspension applications.
