Located in Perth Western Australia, Proformance Motorsport are currently building Australia's most advanced 4WD off road race truck, based on space frame chassis and fibreglass body panels.
Proformance Motorsport use Sway-A-Way Race Runner coil over race shocks with externally adjustable compression and rebound settings, providing the ultimate in suspension performance.
3.0" Swayaway Racerunner Bypass shocks provide a dramatic increase in compression damping as the wheel travel increases. The rates of damping for both compression and rebound are adjustable via the "quick set" valves.
Adjustable Damping is provided by Swayaway Racerunner Race Shocks shown above.
With over 24" (600mm) front wheel travel and 33" (840mm) of rear wheel travel, this truck will fly over the toughest terrain we can find.
Swayaway shocks were chosen due to their exceptional Nickel Plated Finish, Super Hard Nitrided Steel Shafts and shortest "eye to eye" length.
Chrome Molly components are manufactured by Proformance Engineering using specialist CNC machines, providing this vehicle with an amazing 780mm of rear wheel travel to absorb huge bumps found in desert racing.
UNIDRIVE CV Joints will be used between the gearbox and differentials in place of typical uni-joints and tail shafts. This provides a much stronger and smoother drive train. GKN Motorsport performance CV Joint grease will be used to ensure that the joints remain like new.
The UNIDRIVE CV joint pictured above is used to drive the huge 37" BF Goodrich tyres. Pictured next to a cool drink holder gives you an idea of the size of these massive CV joints. Many thanks to UNIDRIVE for the supply of these CV joints.
A custom engineered Proformance gearbox will reverse the output of the engine drive and provide a an adjustable final drive reduction.
The gearbox houses two gears that can be changed in under 30 minutes. A total of 6 gears provide three separate final drive ratios and therefore three top speeds - 140kmh, 180kmh and 240kmh.
Each component of the gearbox has been designed and built specifically for this one of a kind vehicle using specialist alloys from Dicandilo Steel City
3D CAD CAM components are designed and machined in house by Proformance Engineering from specialist materials, using a CNC tool room milling machine and precision lathe.
Four HELLA HID (Xenon High Intensity Discharge) spotlights operate at 25,000 volts turn night into day, essential for high speed navigation during off road racing.
Spotlights are mounted in bearings allowing the navigator to perform adjustments required due to varying traction and fuel loads.

A rear mounted 350 Cubic Inch Chev NASCAR small block will redline at over 8000RPM pushing this awesome truck through rough terrain at top speed of over 230kmh.
This monster engine is equipped with EFI HARDWARE - SPEED TECHNOLOGY fuel injection components.
Huge 37" BF Goodrich Baja Racing Tyres were chosen due to their strength, puncture resistance and race proven performance. Visit BF Goodrich
Our BFG Race Tyres are held in place by SecondAire Internal beadlocks.
The SecondAire internal beadlocks prevent the tyres from "Popping" off the bead in extreme cornering situations and when running low tyre pressures. See how the SecondAire beadlock system works by clicking here
The race vehicle floor is 650mm above the ground plane when at full height, providing the ultimate in ground clearance and wheel travel.
A WOLF 3D ECU will control the fuel injection and ignition to provide the optimum performance and reliability allowing our race prepared motor to provide nearly over 600HP of reliable power.
Custom manufactured Differentials using Precision Gear Dana 60 Ring and Pinions.
Proformance custom manufactured differential housings and transfer case provided exceptional strength and reliability.
Every component of this vehicle will be monitored and displayed using using an AIM Digital Dash/Logger. This awesome Display will be used by Proformance to log and record suspension travel, motor and drive train performance brake temperatures, steering position, cornering force and so on.
The front differential will use a No Spin Detroit Locker from Locked Drive Systems Australia to ensure that the front wheels pull this huge vehicle without wheel spin, yet still provide smooth cornering similar to that of an "open centre" diff.
The Detroit Locker maximizes traction by delivering 100% of the torque to both drive wheels. It is engineered to keep both wheels in a constant drive mode, and has the ability to automatically allow wheel speed differentiation when required.
Four billet Aluminium ALCON racing calipers and huge 330mm "Fully Floating" Brembo disks, provide this race truck with the ultimate in braking.
Custom machined chrome moly front suspension spindles provide this vehicle with the ultimate in strength and reliability.
Planned for completion in late 2008, visit our page regularly as we update this page with the latest photos of our new race truck. Visit the Proformance photo gallery to view our Hummers and other proformance vehicles or to have a chat.
