From farm hauler to race truck
In Australia, a "ute" is a car-based pickup, and for decades Ford and Holden both built them, often with V8s to help with towing and hauling. It didn't take long for owners to start racing them, and by the 2000s there was a dedicated V8 ute racing series with Ford and Holden fans lining the fence.
When local manufacturing ended, the working ute became a mid-size diesel pickup like the Ranger, HiLux, Triton and BT-50, and the series followed. These trucks sell in huge numbers down under, so racing them made sense on paper. After a couple of seasons it was clear the diesels were missing the noise, speed and drama that brought people to the track. The category's fix was to swap in V8s.
A control engine for everyone
Every truck gets the same LS3-based crate engine, built to one spec by Warspeed Industries so no team starts with an advantage. The build is a mild one aimed at reliability as much as power:
- An upgraded camshaft
- Heavy-duty pushrods and uprated valve springs
- A double-row timing chain
- A trunnion upgrade in the rocker arms
Once built, the engines are sealed so nothing can be changed inside after they leave the engine shop.
Where Haltech comes in
Any engine swap needs engine management, and the series chose the Haltech Nexus R5, working with Sieders Racing on the prototype package. Each R5 ships with a locked tune. That matters for parity in three ways:
- The same power curve in every truck on the grid.
- The same engine protection strategies, so nobody can turn off a safety to gain an edge.
- The same throttle response, because the drive-by-wire mapping is part of the locked calibration.
More than an engine computer
The R5 is a vehicle control unit, not just an ECU. Its built-in power distribution runs the truck's body functions too: headlights, turn signals, brake lights and the rain light. That replaces a separate fuse and relay box and a lot of wiring.
The kit comes with pre-terminated harnesses: a main engine harness plus several body sub-harnesses. Haltech has a SuperUtes harness quick start guide for installers, and the Nexus R5 pinout if you want to see what each pin does.
You don't need to be racing a SuperUte to take advantage of the same approach. A Nexus R5 with a terminated LS harness can run an LS swap and replace a fuse box in a street or track car. Our LS terminated harness guide walks through the wiring.
If the engines are equal, where's the speed?
A control engine and a locked tune take power out of the equation, which puts the focus back on the truck and driver.
| Area | What teams can adjust |
|---|---|
| Driver | Still the biggest variable on the grid |
| Suspension | A wide range of geometry settings to suit each circuit and driving style |
| Brakes | A Supercar-style package with a Tilton pedal box and big Brembo six-piston monoblock calipers, with plenty of room for tuning |
| Tires | A control Yokohama semi-slick chosen for grip and predictable wear, so drivers who push too hard early will pay for it late in the race |
Those brakes have real work to do. The trucks run at a minimum of about 1800 kg (roughly 3,970 lb).
Control parts out back
The rear axle is also a spec item: a nine-inch-style rear end with a Detroit Locker-type diff, located with horizontally mounted shocks.
The bed isn't just for looks. Under a hard cover is a rack that holds lead ballast, which the category uses to bring every truck up to the minimum weight. It's the most ute-like part of the whole truck, since it's still carrying a load.
Our take
From a tuning point of view, SuperUtes is a good example of how far a modern VCU has come. One unit handles a V8 with drive-by-wire, engine protection and the whole vehicle's lighting, with the calibration locked so officials can trust every truck is equal. The same features are available to anyone building an LS-powered car. If you're planning one, see the Haltech Nexus range or book a free consultation and we'll help you spec it.
