The Triton Xtreme is the dynamic design by Walkinshaw Group.

The Triton Xtreme sees the enhancement of the Mitsubishi Triton GSR thanks to a collaboration between Walkinshaw Group and Supashock, creating a vehicle catered for both on-road and off-road performance. Some of the enhancements include suspension, wheels and tyres, bash plate and light bar, sports bar, and design elements such as fender flares.

An anticipated 500 units will be made at Walkinshaw Group’s manufacturing facility in Clayton, Victoria, available for purchase through select Mitsubishi dealerships Australia-wide, with the first units on the road in the second half of 2023.

The Mitsubishi Triton is a great core product, and we’re excited to take it to the next level, and create something that is quite unique in the marketplace. Enhancing both on and off-road capability was essential when we undertook this programme. We wanted to ensure the car was right for wherever the customer wanted to go in Australia.

The Triton Xtreme is a Special Edition model featuring design elements from Walkinshaw Group’s Chief Designer, Julian Quincey.

Quincey's impeccable automotive design credentials are demonstrated here with distinctive and striking aesthetics. Immediately you see the Xtreme decals, featured on the bonnet, sides and interior badging. This design mimics Mitsubishi’s Dynamic Shield angular upper grille and light surround, creating a harmonious and prominent visual identifier that is perfectly aligned with the vehicle’s rugged yet distinguished pedigree.

We wanted a clean confident statement with a muscular wide set stance that would complement Mitsubishi’s own characteristic design language.

The suspension upgrades, developed in collaboration with Supashock Advanced Suspension, replaced all 4 dampers and has vastly improved the on and off-road capability of the vehicle.

The Triton Xtreme includes an upgraded 52mm monotube damper with a 20mm rod design, with the front damper running a remote canister and the rear running a piggyback system. Extensive testing and tuning were conducted off-road in the harsh terrains of outback Australia. The result is a valve code that exceeds in off-road performance, whilst retaining on-road precision, comfort, and handling.

Features such as the 46mm piston give Supashock extreme control over the damping characteristics, and the structural design of the dampers has been bolstered. These factors enabled the Triton Xtreme to maintain high levels of vehicle dynamics, and the Triton’s core towing capabilities at a GVM of 2,900kg, and a GCM of 5,885kg.

The Triton Xtreme’s suspension, wheel and tyre configuration exceeded the performance of the base line vehicle in all aspects.

We believe we hit the mark in designing a predictable and confidence inspiring package, worthy of the Xtreme branding. The real magic is achieving high levels of ride quality, whilst greatly improving the vehicle dynamics in performance and response - both on, and off road.
