The LT name arrives
International announced the LT in September 2016. Launch equipment and current S13-era equipment belong to different references.

Choose a reference edition
Start with the model configuration, then choose a publication and explore its documented equipment.
Catalogue reference
Selecting equipment records your research choice. It does not calculate dimensions, establish an available combination or rate a truck.
About this edition & its evidence
2024–25 catalogue, revised January 2026. The printed brochure, rather than the conflicting live webpage wheelbase blocks, controls these values. Equipment choices are catalogue options, not an order compatibility matrix.

04 / MODELS, YEARS & CHANGES
One badge.
Different reference points.
Publication dates and launch milestones do not establish continuous model-year ranges. Match the VIN, production date and equipment era.
Day cab and sleeper get separate sheets
The brochures carry 2024–25 covers and January 2026 revision codes. Their wheelbase ranges differ by cab and axle layout.
International LT 2024–25 sleeper brochure · TAD16011 01/2026 ↗Inspection and build evidence
Identify S13/T14 or Cummins equipment from the build record. Review aftertreatment service, transmission diagnostics, air suspension, fairing repairs and cab-to-trailer clearance.
- line-set/build record
- engine data plate
- T14 or other transmission tag
- ECM/calibration report
- aftertreatment identity
05 / PUTTING IT TO WORK
Match the trailer to the whole truck.
Day-cab duties emphasize local and regional turns; sleeper configurations serve longer-distance work. Trailer clearance and axle loading still depend on wheelbase, fifth-wheel location and equipment.
HIGHWAYTRAILERS.CA
Flatbed
Start with deck length, load placement, axle distribution and cab-to-trailer clearance.
Read the guide HIGHWAYTRAILERS.CAStep deck
Compare deck height, gooseneck geometry and the loaded combination’s height.
Read the guide HIGHWAYTRAILERS.CARGN / equipment hauling
Check neck compatibility, fifth-wheel loading, wet-kit requirements and the complete axle layout.
Read the guide HIGHWAYTRAILERS.CAHow trailer capacity works
Review the tractor, coupling, trailer, tyres and load as one combination.
Read the guidePulling a trailer
Confirm build-specific combination, axle, tyre and coupling ratings, kingpin and service connections, clearance and actual axle weights. GVW is the loaded truck; GCW is the loaded combination. Neither is trailer payload.
Moving the tractor as cargo
Give the carrier measured length, exterior and mirror widths, height, ground clearance and transport weight. Assess deck access, breakover, loaded height and securement together.
Deck height & loaded height ↗There is no single “LT towing capacity”.
The model badge, artwork and catalogue option selectors cannot rate an individual combination. Obtain the actual build limits and scale weights.

Reference-specific evidence needed
- Resolve the conflicting wheelbase blocks on the live LT page against the VIN-linked order.
- Obtain measured exterior width, mirror width, roof/accessory height and fifth-wheel height.
- Earlier A26 / N13 editions and exact production transitions need their own dated references.
