The 2024 International LT can tow up to 55,000 pounds when properly equipped.
Quick answer
- Max Conventional Towing Capacity: 55,000 lbs
- Max 5th-Wheel/Gooseneck Towing Capacity: 55,000 lbs
- Max Payload Capacity: Varies significantly by configuration (often tens of thousands of pounds for tractor applications)
- Gross Vehicle Weight Rating (GVWR): Up to 60,000 lbs (Class 8)
- Gross Combined Weight Rating (GCWR): Up to 80,000 lbs (legal limit for most applications); higher for specific heavy-haul configurations
- Curb Weight: Varies significantly by configuration – typically ranging from 15,000 lbs to over 20,000 lbs for a tractor.
- Hitch Class: Class 8 pintle hitch or fifth-wheel setups are standard for tractor configurations. Conventional ball hitches are not typically offered.
Tow ratings by engine & trim
The International LT is a Class 8 heavy-duty truck designed primarily for tractor applications, meaning it pulls semi-trailers using a fifth-wheel coupling. Conventional towing capacities with a ball hitch are not typically provided, as this is not the intended use. The towing capacity here refers to the GCWR less the curb weight of the tractor and payload within the tractor.
| Engine | Drivetrain | Trim/Package | Max 5th-Wheel/Gooseneck Tow (GCWR - Curb Weight) | Payload (Tractor) |
|---|---|---|---|---|
| Cummins X15 (various ratings) | 4x2, 6x2, 6x4 | Day Cab, Sleeper, Hi-Rise, Mid-Roof | Up to 55,000 lbs (based on 80,000 lb GCWR) | Varies widely |
| International A26 (various ratings) | 4x2, 6x2, 6x4 | Day Cab, Sleeper, Hi-Rise, Mid-Roof | Up to 55,000 lbs (based on 80,000 lb GCWR) | Varies widely |
These figures are illustrative and represent the general capabilities based on common 80,000 lb GCWR limitations for regional and over-the-road hauling. Actual payload for the tractor itself (not the trailer) and the precise tow capacity will depend heavily on the specific engine horsepower/torque, transmission (e.g., Eaton Endurant, Allison), axle ratios, wheel base, and optional equipment chosen. Always refer to the vehicle's door-jamb sticker and specification sheets for exact ratings.
