Understanding the International HV Series: The Swiss Army Knife of Vocational Trucks

The International HV Series, first introduced in 2017, has earned a reputation as the “Swiss Army knife” of the industry—a single platform versatile enough to handle everything from dump trucks and concrete mixers to utility bucket trucks and municipal plows . For the 2025 model year, International has completely redesigned this workhorse while preserving the DNA that made it successful .

Four Models, Endless Possibilities

The HV Series offers four distinct models, each available with multiple BBC (bumper-to-back-of-cab) measurements and axle configurations :

Model	BBC Length	Axle Configurations	Best Applications
HV509	109″	Set-Forward Axle, 4×2, 4×4, 6×4, 6×6	Lighter construction, municipal, utility
HV609	109″	Set-Back Axle, 4×2, 6×4	Better weight distribution for heavier loads
HV515	115″	Set-Forward Axle, 4×2, 6×4	Heavy construction, dump, mixer
HV615	115″	Set-Back Axle, 4×2, 6×4, 8×6 Tridem	Maximum GVWR applications, heavy haul

Gross vehicle weight ratings range from 27,000 to 75,000 pounds, covering virtually all Class 6 through Class 8 vocational applications . Wheelbase options span from 128 to 420 inches, allowing precise matching to specific body lengths and job requirements .

“Internally, we referred to [the HV Series] as the Swiss Army knife of the industry; we didn’t want to disturb that foundation,” said Andy Hanson, International’s vocational marketing director .

The Evolution of Vocational Trucks

The HV Series represents the culmination of decades of development in the vocational truck segment.

The S13 Integrated Powertrain: A New Standard

The headline feature of the redesigned HV Series—available on HV515 and HV615 models—is the International S13 Integrated Powertrain . This isn’t just an engine bolted to a transmission; it’s a fully integrated system where engine, transmission, and aftertreatment were designed together from the ground up .

S13 Engine Specifications

• Horsepower: 370 to 515 hp
• Torque: 1,250 to 1,850 lb.-ft.
• Displacement: 12.4 liters
• Aftertreatment: Dual Stage system with no EGR cooler or DOC

The End of Active Regeneration

One of the most significant advances in the S13 is its elimination of the need for active regeneration . Traditional diesel engines require periodic active regens—injecting extra fuel to burn soot from the diesel particulate filter—which can interrupt work and waste fuel. The S13’s cleaner combustion cycle and advanced aftertreatment design make active regens unnecessary .

This means dump truck operators no longer need to pull over and wait for regens to complete. Concrete mixers keep turning. Utility crews stay on site. Productivity improves without drivers even thinking about the aftertreatment system.

Simplified Maintenance

The S13 achieves its clean emissions through a different approach than previous engines. Engineers eliminated two problematic components entirely :

• No EGR Cooler: The exhaust gas recirculation cooler, a common source of coolant leaks and maintenance headaches, is gone
• No Diesel Oxidation Catalyst: The DOC, which required replacement and contributed to system complexity, is eliminated

The result is a simpler, more reliable engine that spends more time working and less time in the shop.

T14 Automated Manual Transmission

The S13 Integrated Powertrain pairs with the International T14 automated manual transmission, a 14-speed unit featuring :

• Two crawler gears: Ultra-low gears for creeping through jobsites and pulling heavy loads from a dead stop
• One overdrive gear: For efficient highway travel between job sites
• Column-mounted shifter: Integrated with engine braking, allowing drivers to keep hands on the wheel and eyes on the road

Cummins Options for Lighter Models

For HV509 and HV609 models, International offers proven Cummins diesel engines with flexible transmission choices :

Cummins B6.7

• Horsepower: Up to 325 hp (higher for fire/rescue applications)
• Torque: 800 lb.-ft.
• Best for: General construction, municipal, utility applications

Cummins L9

• Horsepower: Up to 400 hp (higher for fire/rescue applications)
• Torque: 1,250 lb.-ft.
• Best for: Heavier vocational work, dump trucks, concrete mixers

Transmission options for these models include Eaton manual transmissions (6, 8LL, 9ALL, and 13-speed) and Allison automatic transmissions (2500, 3000, 3500, 4000, 4500 series with various vocation codes) .

Diamond Logic Electrical System: The Brain Behind the Brawn

The HV Series comes standard with International’s industry-leading Diamond Logic electrical system—a sophisticated platform that transforms how vocational trucks integrate with their bodies and equipment .

Seamless Body Integration

For truck equipment manufacturers (TEMs) and upfitters, Diamond Logic simplifies what used to be complex custom work . The system provides:

• Programmable switches: Customizable controls that can be configured for specific body functions
• Remote power modules: Expanded input and output options with upgraded electronics for more power and control
• Pre-engineered interlocks: Safety features that prevent operation of equipment under unsafe conditions—like preventing a dump body from raising while the truck is moving

Factory-Installed PTO Options

The HV Series with S13 powertrain offers factory-installed single and dual power take-off (PTO) options mounted directly to the T14 transmission . These come with:

• Common North American interfaces for easy equipment connection
• Integrated Diamond Logic controls for seamless functionality
• Warranties matching the transmission (36 months/unlimited miles for rear axle ratings under 52,000 lbs.; 24 months/unlimited miles for higher ratings)

“With our integrated powertrain, we’re now able to offer PTOs installed at the plant,” Hanson said. “And we’re also increasing the amount of lift axles that we offer at the plant—tag or pusher” .

Factory-Installed Lift Axles

Speaking of lift axles, the HV Series offers up to three factory-installed pusher and tag axle locations with weight ratings from 8,000 to 20,000 pounds . When paired with Diamond Logic, these lift axles feature driver-friendly controls that simplify operation and improve payload management.

Visibility: Seeing the Jobsite Clearly

Vocational work often happens in tight spaces—congested construction sites, narrow city streets, crowded utility right-of-ways. The redesigned HV Series addresses this with significant visibility improvements .

Sloped Hood and Panoramic Windshield

The new sloped hood design and panoramic windshield increase forward visibility by up to 53 inches compared to previous models . Drivers can see obstacles, workers, and terrain features much earlier, improving safety and confidence.

Depending on the model, the hood is constructed of four or five pieces made from sheet molded compound, which is easily repairable with a fiberglass patch . The hood also requires 30% less effort to open than previous versions .

LED Lighting

Optional LED headlamps provide 30% better visibility than standard halogen bulbs . Both halogen and LED options feature available heating elements that activate based on ambient temperature, melting snow and ice that could otherwise obscure the lenses .

An automatic high-beam sensor detects oncoming traffic and switches between high and low beams without driver intervention .

Under-Hood Lighting

For early morning pre-trip inspections, an LED work light illuminates the engine compartment when the hood is opened to 30 degrees . This makes it easier to spot leaks, cracked hoses, or other issues before they cause problems on the job site.

Driver Experience: Comfort During Long Shifts

Vocational drivers spend long hours in their trucks—often climbing in and out dozens of times per day. The HV Series includes thoughtful features to reduce fatigue and improve the work experience .

Easy Entry and Exit

New side-of-cab steps assist with ingress and egress . A flexible third step can be installed between the top and bottom steps, with adjustable positioning based on driver preference . This is particularly valuable for drivers who make frequent stops—every climb into the cab is a little easier on knees and backs.

Digital Instrument Cluster

The premium gauge cluster positions key information within easy view, with a customizable digital display that can show up to 15 different gauges . Drivers can monitor:

• Axle loading: Helps optimize weight distribution and maximize payload
• Safety alerts: Critical warnings appear directly in the cluster
• Tire pressure: Monitor tire health to improve safety and fuel economy
• Fluid levels: The integrated fluid check displays oil and coolant status on the dash—drivers can toggle through categories and see either a green check (within tolerance) or red X (fluid needed)

Column-Mounted Shifter

An easy-access, column-mounted shifter integrated with engine braking helps drivers keep their hands on the wheel and eyes on the job . No reaching for a floor-mounted shifter or console controls.

Interior Trim Levels

Two interior trim levels are available :

• Classic: Durable, functional interior for demanding work environments
• Diamond: Enhanced appearance with upgraded materials and finishes

Corrosion Protection: Built to Last

Vocational trucks face harsh environments—road salt in winter, chemicals on construction sites, moisture in utility applications. The HV Series addresses this with comprehensive corrosion protection .

Galvanized Steel Construction

All outside panels utilize double-sided galvanized steel, providing exceptional corrosion resistance . The cab can endure approximately 1,000 hours of exposure before corrosion begins, while frame rails are rated for 2,000 hours .

Multi-Layer Protection

The corrosion protection process includes :

• E-Coat: Epoxy-based electrodeposition primer covering all exposed metal surfaces
• InterCoat ChemGuard: Self-healing coating on toe boards and floor panels—surface cuts, scratches, and perforations maintain corrosion protection thanks to the coating’s self-rejuvenating properties
• Optional LINE-X: Spray-on polyurethane and polyurea liner can be applied inside the cab for extra protection from spills, melted snow, and abrasive materials

Frame Strength: Carrying the Load

The HV Series offers multiple frame rail options to match specific vocational requirements :

• Single rail: Optional 0.5″ thick frame rated up to 3.3 million RBM (Resisting Bending Moment)
• Double rail: Available for even greater strength in severe applications
• Heat-treated alloy steel: 80,000 to 125,000 PSI yield strength depending on specification

Front axles range from 10,000 to 23,000 pounds (non-driving) or 10,000 to 20,000 pounds (driving), with Dana Spicer and Meritor options . Rear axles include single and tandem configurations with capacities from 17,000 to 52,000 pounds.

Suspension Choices

Multiple rear suspension options accommodate different vocational needs :

• Chalmers: 23,000 – 52,000 lbs.
• Hendrickson: RT (34,000-52,000 lbs.), HAS (23,000-46,000 lbs.), HMX (40,000-52,000 lbs.), Primaax (20,000-69,000 lbs.)
• Link: 46,000 lbs.
• International: 20,000-40,000 lbs.

For severe-duty applications, Hendrickson offers the Primaax EX severe-duty vocational rear air suspension system specifically engineered for the HV Series, available with 12-inch ride height and 52,000-pound air disc brake configuration .

Safety Technology: Bendix Wingman Fusion

The HV Series offers the Bendix Wingman Fusion advanced driver assistance system as an available option . This integrated radar and camera system provides:

• Collision mitigation: Automatic braking if a slower-moving or stopped vehicle is detected ahead
• Adaptive cruise control: Maintains set following distance
• Lane departure warning: Alerts if the truck drifts out of its lane
• Stationary object alert: Warns drivers of stopped vehicles in the lane ahead
• Following distance alerts: Helps drivers maintain safe gaps

Service and Support: Beyond the Truck

International has developed comprehensive service solutions specifically for the HV Series, recognizing that vocational trucks need to stay working .

Service Contract Options

Multiple service contract levels are available :

• Core: Planned maintenance with select chassis items, 84-point inspection, proactive service planning
• Extended: Adds extended powertrain service coverage
• Complete: Extended non-powertrain and chassis service coverage including cooling, HVAC, electrical, suspension, steering, axles, brakes, and fuel systems

Term options include 3 years/100,000 miles, 4 years/150,000 miles, 5 years/200,000 miles, and 5 years/350,000 miles (mileage-based) .

Uptime Advocates

International employs “uptime advocates” who monitor vehicle telematics data to identify maintenance needs before they become failures . When an issue is detected or a PM interval approaches, they proactively contact fleet managers to schedule service at convenient times.

“When it’s time for either a PM or if we see something that could down a vehicle, we call that fleet manager and that owner and we proactively say, ‘It’s time for your PM in a week or so’ or ‘We see something that will need to be handled,’ and we’re able to work with our dealers and schedule those events” .

Proactive Service Planning

Dealers can schedule service events with more accurate time windows, allowing drivers to drop off trucks, get needed service in a few hours, and return to work—rather than leaving trucks overnight .

Commonized Components: Making Life Easier for Upfitters

One of the most significant improvements in the redesigned HV Series is the commonization of chassis components across models . Upfitters previously had to deal with different component locations depending on configuration, adding complexity and cost. Now, critical components are positioned consistently:

• Fuel water separator
• Air dryer
• Air tanks
• Electrical connection points

This means body builders can develop standardized mounting solutions that work across multiple HV configurations, reducing custom fabrication and improving quality .

Upfit Feature	Benefit
Commonized component locations	Reduced complexity for body builders, faster turnaround
Factory-installed PTOs	Precise fit, integrated controls, full warranty
Up to three factory lift axles	Customized capacity without aftermarket modification
