What is the International HX?
International places the HX in its severe-duty range. The manufacturer includes HX applications in its S13 Integrated Powertrain material, but individual trucks can differ by year and build. The job body, frame and axle arrangement are the starting point for a meaningful HX specification.
What matters in a comparison
An HX comparison should describe the maximum working loads and site conditions, not just a preferred engine rating. Ask the body builder to confirm the chassis interface and PTO needs. When looking at used equipment, separate truck age from body age and check both histories. Add specialized equipment maintenance and non-driving work hours to the ownership discussion.
Questions to take to the supplier
- What body and application approval accompany the chassis?
- Which PTO and transmission specification is installed?
- Are truck and body service histories both documented?
