Proformance IFS IRS 4WD Trophy Truck Narrow Diff Long Wheel Travel

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.

4WD ULTRA4 IFS IRS TRANSFER CASE

At Proformance Motorsport, we pride ourselves on our innovation and unique concepts. A typical innovation is the Jig we manufactured to support our Race Transmission and Transfer Case whilst we install and remove the engine. The jig allows our team members to simply slide the gearbox back and forth on roller bearings to make fitting the gearbox a breeze.

Quick Change Transfer Case Off Road

Our Mid Mounted Engine required the gearbox output direction to be reversed to ensure the Rear Diff was being driven in the correct rotation direction. Driving a Rear Diff upside down and on the Coast Side of the Ring Gear was NOT acceptable for our team, so we made our very own transfer case, which today is available in our product range to teams all over the world

Our 4WD Trophy Truck Chassis was 10% hand built in our own premises. With no Trophy Trucks in Western Australia and NO other hand made 4WD vehicles in Australia at all, we faced all sorts of challenges with this concept, but after 10 years, we had it all sorted and the result was amazing

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)
