Notes:
1. Axle structure rating only. Ratings for brakes and wheel-end components differ depending upon options chosen.
2. Suspension ride heights must be set within Hendrickson specifications to provide load equalisation among axles and to ensure proper suspension performance. Failure to maintain proper ride height settings can lead to suspension, axle or trailer damage.
3. Greater than 10% off-highway requires Application Approval.
