N-Series Gas Features
Water Channels
Smart Water Control for a Cleaner, Safer Ride
Visibility is key and that is why Isuzu truck roofs are designed to direct water away from the windshield for better visibility. The channels also help minimize pooled water spilling over the door which keeps you drier when you exit the cab.
Spacious Interior
Comfort You Can Count On.
Step into a cab designed for long days on the road. The refined two-tone grey interior sets a modern, professional tone, while seats finished in a grey-and-blue cross-pattern tricot fabric blend style, comfort, and everyday durability. It’s an interior built to look good, feel great, and stand up to the demands of your work.
LED Lighting
Brighter, Safer, Smarter
LED headlamps and daytime running lights blend utility with modern style. Delivering brighter, clearer illumination, these lights enhance nighttime visibility for drivers while making your truck more noticeable to pedestrians and oncoming traffic—helping you stay seen and stay safe.
Brakes and Suspension
Stop Strong, Ride Smooth.
The four-wheel disc braking system incorporates vacuum and power assist to ensure superior stopping power and precise pedal response for reliable performance in any condition. The Anti-lock Braking System (ABS) and the Electronic Brakeforce Distribution (EBD) help ensure you’ll enjoy confident handling and safety on every job.
The multi-leaf suspension system is designed to handle the toughest loads and roughest roads. The layered leaf design absorbs shocks and helps your truck stay balanced and responsive, keeping you and your cargo steady and smooth throughout the workday.
