Safety baked in.

All Giga Series cabs comply with global ECE-R29 and ECE-R93 safety standards. Double side-intrusion bars, seatbelt pre-tensioners, driver's SRS airbag and ABS come as standard.

masonry-image Multimedia Unit

Multimedia at your fingertips.

Stay safe and connected with our Isuzu Multimedia System. Its big 6.2” display and intuitive menu means you keep your focus on the road. It connects to your mobile to read out your messages. It includes voice-control and hands-free Bluetooth as standard. It comes sat-nav ready with optional tyre-pressure monitoring*.

masonry-image Automated Manual Transmission

Shift to Aussiematic.

The Automated Manual Transmission (AMT) in the Giga Series has been built specifically for Australian trucking demands and features improved calibration for local conditions.

masonry-image ISRI Seats

The best seat in the business.

The ISRI 6860 driver’s seat is the CEO of air-suspension seating. Standard in Giga Series, its ergonomic and safety features include integrated seatbelt with pre-tensioner, head restraint, dual-stage air lumbar/lateral support, integrated pneumatic system, adjustable shock-absorber and body-hugging upholstery from head to knee.

masonry-image Electronic Cruise Control

Control your speed, and your climate.

Advanced electronic cruise control is standard and automatic climate control air‑conditioning is available in selected models. Just two more ways that Isuzu can help you stay comfortable as you cruise.

masonry-image Meritor axle

The apex of axles.

Meritor steer and drive axles are the benchmark for heavy trucks. Fitted to all Giga Series models, Meritor offers high capacity and driver-controlled cross locks to keep you from getting stuck.

masonry-image Air Suspension

Suspended on air.

Most Giga Series trucks come with an Isuzu or Hendrickson airbag rear suspension. These help deliver a stable ride for the load and the driver. Some models feature an in-cab remote to let you adjust the ride-height from your seat.

Cabs are anything but an afterthought with Isuzu. You’ll find stacks of storage space and places for all your stuff. Naturally, there’s plenty of room for you and your workmates, including stretch-out legroom. We make our cabs so accommodating, you may never want to leave.
