From Euro6 emissions compliance to upgraded horsepower, the 2025 Sitrak G5S 8×4 Agitator is everything a game changer should be. Purpose-built and engineered for Australia’s toughest concrete jobs, it raises the bar on performance, safety, and driver comfort.

City Fleet Sitrak crafted the G5S chassis and cab specifically to withstand gravel pits, urban job sites, and regional haul routes, with a robust 8×4 frame built for high-payload agitator bodies, pre-drilled chassis rails for seamless body fit-outs.

They’ve even strategically placed fuel and AdBlue tanks for stability and easy access. This rugged platform keeps service downtime to a minimum and supports concrete operations in the harshest environments.

Under the bonnet, the G5S boasts a diesel engine pushing out 350HP, with a refined torque curve ideal for stop-start mixing and heavy loads. A diesel particulate filter provides for cleaner urban running, while a heavy-duty transmission makes PTO use a simple operation.

Compatible with STG, Hyva, and other agitator bodies, the G5S delivers responsive throttle control, fuel efficiency improvements, and compliance with Australia’s latest emissions standards.

There’s plenty of safety tech too, ensuring minimal risk on job sites, including EBS, ABS and trailer brake control, ESC and roll stability control, blind spot mirrors with optional rear-view cameras, and hill start assist, for when you need to control the climb.

These technologies reduce the risk of rollovers, collisions, and on-site incidents, protecting drivers, loaders, and pedestrians alike. Long days behind the wheel are a thing of the past too, with an interior that features a digital instrument cluster with dual-display layout.

ISRI air-ride seats with heating, lumbar support, and vibration damping are standard, along with low-noise insulation and a refined HVAC system for climate extremes. Ergonomic controls and adjustable steering column complete the package.

This driver-focused environment boosts visibility, reduces fatigue, and helps operators stay sharp on every pour. Whether you’re running a single agitator or an entire ready-mix operation, the G5S can be adapted to your needs.

With flexible axle spacing for weight distribution and suspension tuning, steel or aluminium fuel tanks to meet duty-cycle demands and reinforced chassis reintegration points for quick body swaps, the G5S, is a standout.

High-load-rated suspension packages for rough-road stability adds capability too. Equally as important is the support offered by City Fleet Sitrak’s extensive service network across Australia.

Warranty coverage includes a 3-year/600,000 km bumper-to-bumper warranty, and a 3-year/1,000,000 km driveline coverage, with extensions available. Fixed-price maintenance plans and genuine parts supply are also available, along with 24/7 roadside assistance.

This support framework minimises unplanned downtime and stabilises whole-of-life operating costs for concrete fleets of any size. For fleets and owner-drivers ready to step up their concrete game, the G5S is the agitator to beat.
