Diamond Logic®

Offering nearly 200 available body integration and driver efficiency features, the innovative and customizable Diamond Logic® electrical system maximizes productivity, safety and performance.

Over-The-Air Programming

Allows two-way engine communication and secure wireless engine reprogramming to optimize the performance of your vehicle, all while reducing service trips and downtime.

Proven Power.

From the trusted performance of the Cummins ISL9 to the beefy durability of the Navistar N9 and N10 and on to the big bore muscle of the N13, the WorkStar® offers the right engine for any configuration and for every job.




A Lightweight Heavyweight.

With its single-frame rail system, you’ll enjoy a responsive lighter weight chassis that still delivers a high strength-to-weight ratio plus easier chassis modifications.

Higher Power.

With available radiator placement above the frame rails, you get a cooling system that accommodates uninterrupted front engine power takeoff (FEPTO) for maximum ground clearance and durability in both on- and off-road environments.

Extend Your Capabilities.

A single-frame rail system, including a 3.35 rbm single frame rail that gives multiple options. Available front frame extensions easily modify your application, moving the bumper forward for mounting pumps, winches and other equipment.

Corrosion Resistant Cab.

Built to last, a five-step paint process helps prevent cab corrosion and fading. Own your truck with confidence with a 12-month unlimited-mile warranty for paint and a 60-month unlimited-mile warranty for cab corrosion.

Optimum Chassis Strength.

Give it all you’ve got; this truck can take it. A nearly indestructible huck-bolted chassis boasts greater clamping load that won’t loosen under pressure. Meaning more time on the job and less time in the shop.

Driver Satisfaction


Any Extreme. Any Time.

Year-round jobs demand year round performance. Clear sightlines offer improved visibility in harsh environments. Available heated windshields prevent snow and ice accumulation on wipers and cowl.

Off Road. On Site.

Standard set-forward and set-back axle configurations give you up to 50-degree wheel cut for maximum maneuverability both on the street and in rugged environments.

See More. Do More.

Easily navigate job sites with best-in-class visibility from an available sloped hood (not available with FEPTO placement). Improved sightlines offer confidence and better maneuverability.



Electronic Stability Control.

Available electronic stability control ensures HX® Series vehicles maintain steadiness and steerability during heavy brake applications and braking on slippery surfaces. Providing drivers with improved safety and greater confidence behind the wheel.

Air Disc Brakes.

An available option for both front and rear applications, air disc brakes provide shorter, surer stops, better braking feel and more braking power for improved safety. All while offering longer lining and rotor life and requiring less maintenance.

Bendix® Wingman® Advanced.

An option on select WorkStar® vehicles, Bendix® Wingman® Advanced combines collision mitigation and stability technologies that are designed to assist drivers in rollover, collision and loss-of-control situations.
