Proformance Motorsport

4WD Trophy Truck - Off Road Racing 

Located in Perth Western Australia, Proformance Motorsport construct and race some of Australia's most advanced 4WD off road racing trucks.

 

Back in 1990 our "Imagineers" began creating our own Gearboxes, Differentials, Hubs, Spindles and Chassis for our personal use. With the exception of the engine and wheels almost all our components were hand made in our own premises to provide us exactly what we needed.

 

The components we manufactured have gained worldwide attention and after many requests from the Off Road Motorsport Communites around the world, team owner Scott Bryce finally decided to begin a business making and selling these unique components worldwide.

Ultra4 Ultra 4 Power Steering Ram

Narrow Diffs requires that the A Arm Pivot Points be close together also. Traditional Off Road Steering Racks like Fortin, Howe and Pro Am are not typically suitable for 4WD Trophy Trucks or ULTRA 4 Rock Racers because the steering input shaft needs to be positioned right where the Front Diff is installed. Getting the steering pivots to line up with the A Arm pivots is difficult enough without having to worry about steering columns that have 10 or more Uni Joints (we have seen it before)
