    1. Capacity of slider system only; axle not included.

    2. Suspension ride heights must be set within Hendrickson specifications in order to provide load equalization among axles and to ensure proper suspension performance. Failure to maintain proper ride height settings can lead to suspension, axle or trailer damage.

    3. To calculate total system height for HK sliders, add the suspension ride height and 8.5 inches for the slider box. For the HTHKR ramp-ready slider, add the suspension ride height and 14 inches for the slider box.
