• Optimized Traction (OT) Mode

    Drops the pounds to carry the weight

    The system’s default setting, OT balances the weight between the two rear axles when the tractor is loaded. If wheel slip is detected, the system can temporarily increase load to the drive axle for 30 seconds to provide improved traction.

  • Basic Traction (BT) Mode

    Splits the load 50/50

    Lowers the lift axle regardless of suspension load and maintains a 50/50 load split between the lift axle and drive axle during loading or unloading, prolonged stops or areas that require 50/50 load splits between tandem axles.

  • Lower Cost of Ownership

    When the load is empty and the axle lifts, the tractor operates as a 4x2 for less drag, better fuel efficiency and reduced tire wear, which helps lower fuel and maintenance costs.

  • Uptime by Design

    With the drive axle in the rear position, weight gets distributed more evenly—limiting wear and extending life. The weld-free assembly allows for easy alignment, and the R-series drive spindles simplifies maintenance by using the same wheel end equipment as the drive axle.
