Brains and Brawn


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.

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.
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®.
Concrete Mixers
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.
Streets & Sanitation
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.
Fire & Rescue
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.


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.
