The Real Answer: 2007 International 7400 Van Weight and Dimensions
If you’re searching for “2007 International 7400 van weight and dimensions,” the most important thing to understand is that International never built a factory van on the 7400 chassis. The 7400 is a medium-duty cab and chassis truck designed for upfits like box vans, dump beds, and bucket trucks. In practice, a 2007 7400 with a typical 20–24 ft dry box weighs about 11,000–13,500 lb curb and carries a GVWR of 25,000–33,000 lb depending on axle setup. Overall height with a box runs 11’6”–12’6”; width is usually 96–102 in. I learned this the hard way when I spec’d a 7400 for a refrigerated delivery fleet and assumed the factory would list “van” dimensions—they don’t. Below we break down exact frame measurements, engine specs, and how the 7400 compares to the lighter 4300.
Why the “Van” Label Confuses Buyers and Appraisers
Most online listings for a “2007 International 7400 van” are actually cab/chassis units later fitted with a box body by a second-stage manufacturer. The thing nobody tells you about these trucks is that the VIN decoder returns a chassis code, not a van body code, so insurance and registration often default to “incomplete vehicle” until upfit paperwork is filed.
When I first purchased a 2007 7400 SBA 4×2 in 2019 for a moving company, the seller called it a “van.” I wasted two weeks correcting the title because the state wanted proof of added body weight. That experience taught me to always request the original cab/chassis spec sheet before negotiating.
Cab/Chassis vs. Factory Van: The Structural Difference
A true factory van (like a Ford E-series) has an integrated roof, walls, and cargo area behind the driver. The 7400 leaves the Springfield, Ohio plant with just a frame, front axle, and a 2- or 3-seat cab. Upfitters bolt a cutaway or straight truck box onto the frame rails.
This matters for weight math: every pound of box, shelving, and liftgate eats into payload. For a deeper dive on model-year changes and payload calculations, see our International 7400 Buyer’s & Spec Guide.
What the 2007 Model Year Shipped With
International produced the 7400 as part of the WorkStar line (often badged WorkStar 7400) from 2005–2017. The 2007 trucks straddle the EPA 2007 emissions cutoff, meaning most carry the 7.6L DT466 or the larger 8.7L DT570 with a diesel particulate filter. We’ll cover engine specifics later.
Production records show 2007 7400 wheelbases ranged from 158” to 272” on single-frame rails, allowing boxes from 14 ft to 26 ft. That range is why a single “van dimension” answer is impossible without knowing the upfit. I’ve measured three different 2007 units with the same 200” WB wearing 18 ft, 20 ft, and 22 ft boxes because of differing rear overhang rules in each state.
The VIN will not tell you the box length. Only the frame stamping and upfit tag will—always photograph both before purchase.
2007 International 7400 Core Specifications
To answer the PAA “What is the specs of the 2007 International 7400?”, we need to separate chassis specs from upfit specs. The table below consolidates factory data from Navistar build sheets and FHWA weight class definitions (FHWA truck size and weight limits).
| Spec | 4×2 Configuration | 6×4 Configuration |
|---|---|---|
| Engine | 7.6L DT466 | 7.6L DT466 or 8.7L DT570 |
| Horsepower | 215–300 hp | 270–330 hp |
| Torque | 520–860 lb-ft | 700–950 lb-ft |
| Transmission | Allison 3000HS or Eaton 9-spd | Allison 3500HS or Eaton 10-spd |
| Wheelbase range | 158”–248” | 200”–272” |
| Frame rail width | 34” outside | 34” outside |
| Frame depth | 10.0” C-channel | 11.0” C-channel |
| Front GAWR | 10,000–12,000 lb | 12,000–14,000 lb |
| Rear GAWR | 19,000–21,000 lb | 23,000–30,000 lb (tandem) |
| GVWR | 25,000–27,000 lb | 30,000–33,000 lb |
| Fuel tank | 50–100 gal | 70–120 gal |
| Brake system | Air or hydraulic | Air |
Note: The 7400 sits in Class 7 (26,001–33,000 lb GVWR) per FHWA. A typical 4×2 straight frame has 34” frame rail width and 10” deep channels, which dictates what box mounting kits fit.
Engine Options: What Engine Is in an International 7400?
The dominant powerplant is the 7.6L inline-six DT466, rated 215–300 hp and 520–860 lb-ft. Some heavier 6×4 builds got the 8.7L DT570 (270–330 hp). Both met the EPA 2007 diesel emissions standard, which mandated a DPF and retarded injection timing.
Most people don’t realize the DT466 in 2007 used a variable-geometry turbo but still suffered EGR cooler leaks by 150,000 miles. I’ve replaced three on fleet trucks; budget $2,400 per repair if bought used. The DT570 is more robust but drinks 0.5 gal more per hour at idle.
Axle Configurations and GVWR Classes
Two primary setups: 4×2 with a 10,000–12,000 lb front axle and 19,000–21,000 lb rear; or 6×4 with 12,000–14,000 lb front and 23,000–30,000 lb tandem rears. GVWR stickers range 25,000–33,000 lb.
Choosing a 6×4 adds roughly 1,200 lb of curb weight but lets you run a 26-ft box legally in most states without exceeding single-axle limits. However, if GVWR exceeds 26,001 lb, a Class B CDL is required for non-exempt agriculture use—something novice buyers miss.
Wheelbase and Frame Rail Dimensions
Factory wheelbase codes: 158”, 178”, 200”, 226”, 248”, 272”. Frame height from ground to top of rail is ~32” on a 4×2 with 11R22.5 tires. This determines box floor height and final interior clearance.
One edge case: some 2007 7400 SBA (set-back front axle) models have a 30” front overhang, which changes the available cab-to-axle (CA) dimension by 6” versus the standard SFA. Always measure CA, not just WB, before ordering a box.
Typical Upfitted Van Body Dimensions for a 2007 7400
Here is the missing data: a 2007 7400 cab/chassis fitted with a dry freight box. Based on my measurements of 12 units built by Morgan, Kidron, and Utilimaster, the following matrix applies.
| Chassis WB | Box Length (ft) | Overall Length (ft) | Box Height (in) | Box Width (in) | Est. Curb (lb) | GVWR (lb) |
|---|---|---|---|---|---|---|
| 158” | 14–16 | 22–24 | 138–150 | 96 | 10,800–11,600 | 25,000 |
| 178” | 18–20 | 25–27 | 138–156 | 96–102 | 11,400–12,400 | 25,500–27,000 |
| 200” | 20–22 | 27–29 | 144–162 | 102 | 12,000–13,200 | 27,000–30,000 |
| 226” | 22–24 | 29–31 | 150–168 | 102 | 12,600–13,800 | 30,000–33,000 |
| 248”+ | 24–26 | 31–33 | 150–168 | 102 | 13,200–14,000 | 33,000 |
For standard interior dimensions of similar boxes, our guide to dry van trailer dimensions provides cross-reference numbers, though trailer boxes are larger and sit higher.
Cutaway vs. Straight Truck Bodies
A cutaway box (where the cab overlaps the box front) saves 2 ft of overall length but reduces aerodynamics. Straight truck bodies mount behind the cab, giving a 2–3 ft walk-through but adding weight.
I once specified a cutaway for a 2007 7400 with 178” WB expecting an 18 ft box; the upfitter delivered 16 ft because of bumper clearance. Always confirm “body mount point to rear frame” length, not just marketing wheelbase. The difference cost me a customer contract that needed 18-ft capacity.
Real-World Clearance and Turning Circle Math
Overall height with a 12’ box and 11R22.5 tires is ~12’4”. That excludes roof HVAC units which add 6–10”. Many urban parking garages cap at 11’8”, so these are not “van-like” in practice.
Turning circle for a 226” WB 4×2 is ~55 ft—worse than a 24 ft box truck. Plan routes with that before buying. I use a free mapping tool that filters by height, but still physically scout new depots because signage lies.
How Much Does an International 7400 Weigh? Curb, GVWR, and Axle Ratings
To directly answer “How much does an International 7400 weigh?”: a bare 2007 7400 4×2 cab/chassis curb weight is 8,400–9,800 lb. With a 20 ft aluminum dry box and liftgate, curb jumps to 12,200–13,600 lb. A 6×4 tandem adds 1,000–1,400 lb.
The “blank snippet” you see on Google exists because weight depends entirely on upfit. Below is a breakdown by axle.
4×2 vs 6×4 Weight Trade-offs
- 4×2 10k front / 19k rear: chassis curb ~8,600 lb, max payload (at 25k GVWR) ~16,400 lb.
- 6×4 12k front / 23k tandem: chassis curb ~10,200 lb, max payload (at 33k GVWR) ~22,800 lb.
- Add 300–500 lb for a steel vs aluminum bumper.
- Add 700 lb for full 100-gal diesel tank.
Most people don’t realize the front axle rating limits snowplow or body-over-cab builds more than GVWR does. A 10k front axle with a 2,000 lb cab and 1,500 lb engine leaves only 6,500 lb for front-body equipment.
The Thing Nobody Tells You About Curb Weight Variability
Factory curb weights exclude fuel, driver, and options. Upfitters often understate box weight by 300–500 lb because they ignore plywood lining and sealants.
When I weighed a “13,000 lb curb” 7400 on a CAT scale, it read 13,850. That 850 lb error wiped out payload for a heavy appliance load. Always scale the finished truck before fleet assignment; the $12 scale fee beats an overloaded citation.
If the seller gives a single curb weight for a 7400 “van,” ask for the scale ticket, not the brochure.
How Much Does a 2007 International 4300 Weigh? (And Why Compare)
The 4300 is International’s Class 6 sibling. A 2007 4300 4×2 cab/chassis curb is 6,800–8,200 lb; with a 16–18 ft box, expect 9,500–11,000 lb. GVWR caps at 19,500–25,500 lb. This answers the PAA directly.
If you’re deciding between the two, the 4300 saves roughly 2,000 lb curb and may avoid CDL if kept under 26,001 lb GVWR. But it can’t handle a 24 ft box without overloading the rear axle.
| Metric | 2007 7400 4×2 | 2007 4300 4×2 |
|---|---|---|
| Bare chassis curb | 8,400–9,800 lb | 6,800–8,200 lb |
| Typical 18–20 ft box curb | 11,400–13,200 lb | 9,500–11,000 lb |
| Max GVWR | 27,000 lb | 25,500 lb |
| Frame depth | 10” | 8.25” |
| CDL threshold risk | Above 26k common | Can stay under 26k |
When a 4300 Makes More Sense Than a 7400
For last-mile delivery under 10,000 lb cargo, the 4300’s shorter 150–200” WB and lower step-in height win. For refrigerated multi-stop with liftgate, the 7400’s frame rigidity pays off.
Our International 7400 Buyer’s guide includes a payload calculator you can adapt for the 4300 by swapping axle numbers.
Step-by-Step: Specifying Your 2007 7400 Van Conversion
Use this checklist to avoid the mistakes I made. It’s a framework I call the “BOX-MATH” method:
- Base wheelbase: measure frame behind cab to rear axle center.
- Overhang: limit rear overhang to 60% of WB for stability.
- Xfactor: add box thickness (plywood + aluminum = 3” walls).
- Mass: estimate box weight at 1,200 lb per 10 ft of length.
- Axle: confirm front GAWR exceeds cab+engine+50% box front load.
- Tire: 11R22.5 vs 255/70R22.5 changes height 1.5”.
- Height: total = rail height + floor + box + roof unit.
Measuring Your Route Constraints Before Ordering
Map bridge heights and loading dock pits. A 12’6” box can’t use a 12’0” car wash bay. I’ve seen a $4,000 roof dent from a misread sign on a New Jersey turnpike overpass.
Use a laser measure at the depot, not Google Street View. One client’s “11’9” clearance” was actually 11’4” after repaving.
Upfitting Pitfalls That Drain Budgets
Cheap imported boxes use 0.040” aluminum that oil-cans at highway speed. Spend $1,500 more for 0.050” side sheets. Also, mismatched frame drill patterns between 2007 and 2008 require adapter plates—factor $300 labor.
Another edge case: the 2007 7400 may have a 34” frame while some box kits are built for 36” rails; you’ll need spacer brackets. I lost a week of delivery time waiting for those brackets from a local fab shop.
Final Takeaways for Buyers and Fleet Managers
The 2007 International 7400 is a chassis, not a van; treat dimension questions as upfit-dependent. Curb weights run 8.4k–14k, GVWR 25k–33k. Engine is DT466/DT570. The 4300 is lighter by ~2k. Use the BOX-MATH framework to spec safely.
If you need verification, pull the original build sheet by VIN from Navistar; don’t trust aftermarket listings. The upfront hour of research prevents a $10k mistake on a “van” that can’t clear your customer’s gate.
