The International Workstar
No matter what you throw at it, there’s just no stopping WorkStar®. With the broadest range of available powertrain options, it can muscle its way through even the heaviest loads and the most rugged jobs. Couple that power with an electrical system that offers body control functionality and more efficient diagnostics, and you’ve got a truck with the brains and brawn to keep your business running at its best.
Just because the job is demanding, doesn’t mean the work has to be. On the outside, the International® WorkStar® brings all the muscle to the roughest environments. Inside, its large, comfortable cab offers drivers high-visibility and operability to expertly tame even the most grueling of worksites.
Workstar Heavy Haul
When hauling heavy loads, there’s no room for second guessing. With its broad range of proven and reliable powertrain options, durable single and double-frame rail offerings and a rugged wide track front axle with up to a 50°- degree wheel turn angle, confidence comes standard with every WorkStar®.
You, better than anyone, know a structure is only as good as its foundation. That’s why every WorkStar® is built on a huck-bolted frame and cross-member system to deliver maximum vocational durability and a number of frame-rail options, all designed to withstand even the harshest of job site conditions.
In the refuse business, there’s no room for a throwaway rig. So we packed the WorkStar® with high-durability features proven to stand up to the rigors of the job, together with driver-centric comforts and controls for a smooth ride and easy operability along every route.
Workstar Snow Plows
Extreme weather calls for an extreme truck. That’s where the WorkStar® comes in. A nearly indestructible huck-bolted chassis boasts greater clamping load that won’t loosen under pressure. And a five-step paint process helps prevent cab corrosion and fading.
Supplying your customers with essential utilities is no small feat. Which is why the International® WorkStar® is no small truck. Maximum durability and all-wheel-drive mobility take you anywhere you need to go. While a spacious, quiet cab and ergonomic controls make it comfortable to get there.
When the job takes you 50 feet into the air, you need a truck that will keep you well grounded. With an exceptional range of power, axle and cab configurations, plus integrated Diamond Logic® system controls, an International® WorkStar® puts all the features you need well within reach.
Being prepared for everything, means being ready for anything. When the call comes, the WorkStar® is there with all-wheel drive performance and robust power to take you where other trucks can’t go, plus Diamond Logic® programmable safety features to automatically protect equipment and ensure years of reliable service.

Engineered for reliability, durability and fuel efficiency, the Cummins B6.7 doesn’t have an off day. With an impressive range of horsepower for a variety of medium-duty applications, every aspect of the B6.7 has been improved to deliver the lowest cost of ownership with maximum uptime. Add in industry leading service from International® Trucks and Cummins, plus a two-year, unlimited mileage engine warranty, and you’re sure to have an engine that’s always ready to work when you are.
The B6.7 features High Pressure Common Rail (HPCR) fuel injection for constant pressure and strong performance at every rpm. Multiple injection events per cycle make this engine quiet and smooth to operate. Ratings range from 200-325 hp (149-242 kW).
A great track record of established performance continues to improve with the Cummins L9. With the highest power density of any engine in its class, the L9 delivers the right amount of might to even the heaviest medium-duty applications.
The L9 shares common technology with the Heavy-Duty ISX15 and ISX12 to deliver exceptional performance. Common components include the XPI fuel system, a high-capacity electronic control module (ECM) and the patented Cummins VGT™ Turbocharger from Cummins Turbo Technologies. Ratings range from 260-380 hp (194-283 kW), with 550 lb.-ft. of clutch engagement torque. Optional features include engine braking for better control, rear-engine power take off (REPTO) and front-engine power take off (FEPTO).
Built on the same proven I-6 platform as Navistar’s legendary DT engine, the Navistar N9 grew from a big idea: bring traditional big bore features such as wet-sleeve design and in-chassis rebuild capability to the midrange diesel market. New features including increased 9.3-liter displacement by longer stroke, dual sequential turbo technologies, single-piece gallery-cooled steel pistons and crankcase ladder reinforcement enhance reliability, durability and productivity.
The N9 is compatible with a full range of automatic and manual driveline options and thousands of potential build configurations to serve the broadest range of on- and off-highway applications. Ratings offer up to 330 hp and 950 lb.-ft. of torque. Shift energy management technology allows for higher peak torque when used with select transmissions.
Just because you run medium-duty trucks, that doesn’t mean you can’t have heavy-duty power. That’s why there’s the Navistar N10. The N10 grew from a big idea: bring to the midrange diesel market traditional big bore features such as wet-sleeve design and in-chassis rebuild capability. Built specifically for the needs of International® customers, the high-output N10 takes your business further with increased 9.3-liter displacement by longer stroke and the performance you’d expect from larger heavy-duty engines – all in a weight-saving design.
The N10 is compatible with a full range of automatic and manual driveline options and thousands of potential build configurations to serve the broadest range of on- and off-highway applications. Ratings offer up to 370 hp and 1,250 lb.-ft. of torque. Shift energy management technology allows for higher peak torque when used with select transmissions.
N10 engines use dual sequential turbochargers to deliver powerful performance for any job. The smaller, primary turbo responds quickly for immediate takeoff at low engine speeds, and the larger, secondary turbo provides peak power at higher speeds and on steep grades.
Compacted graphite iron (CGI) delivers higher strength and more fatigue resistance than traditional gray iron. Navistar has always used compacted graphite iron for the N13 crankcase. Single overhead camshaft uses industry-leading assembled camshaft technology. This allows lobes to be produced from tool grade steel, delivering unsurpassed durability. Single stage EGR cooler has been designed to maximize durability. The no fin design delivers consistent performance by preventing soot plugging. Stainless steel throughout the EGR cooler prevents corrosion. Laser welding delivers excellent thermal fatigue resistance. 2200 bar high pressure common rail fuel system precisely controls fuel atomization, with multiple injection technology. Smooth engine operation and clean combustion extend engine life. Foamed wiring harnesses allow mounting brackets to be molded into the wiring harness. Bolts secure the wiring harnesses, delivering the most consistent routing and clipping of any wiring harness technology. Polymer coated bearings are used on the crankshaft main journal bearings and connecting rod bearings. When oil pressure is low, such as while starting the engine, the coatings protect the engine from wear as oil pressure builds.
