1. Capacity of primary suspension 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. The HT250T is intended for use as a liftable suspension, in combination with other HT primary models. It may also be used in place of an HT230 when the application calls for high travel or low ride height.
