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.

Proformance Motorsport 4WD Trophy Truck with BOTH IFS and IRS (Independent Front and Rear Suspension). Proformance Motorsport Ultra Narrow Differentials allow for Much Longer Axles and therefore much more wheel travel. Our CV Joints are tucked up inside the DIFF Carrier and inside the wheel hub, using huge taper roller bearings. This 4WD truck has an amazing 33" Rear Wheel Travel IRS and 22" Front Wheel Travel IFS This wheel travel is achieved with only 22 degrees of CV Joint angle

Proformance 4WD Trophy Truck - Located in Perth Western Australia. Independent front and independent rear suspension using Proformance Motorsport ULTRA Narrow Differentials. Our Differentials are only 40mm Wide (Between the CV Faces) and are MUCH NARROWER than SipderTrax (Spider Trax) and Currie 9 Inch or 10 Inch IFS and IRS Differentials. Our Ultra Narrow Differentials are suitable for Off Road Racing, Ultra 4 Rock Racing, Rock Bouncing and other forms of Off Road Motorsport.

Proformance Ultra Narrow Diffs provide the ultimate in IFS and IRS wheel travel. Our vehicles provide MUCH MORE wheel travel than ULTRA 4 and Rock Bouncers. Proformance Motorsport Drivetrain Components include ULTRA Narrow Diffs which have CV joints mounted up inside the Diff Carrier to allow for the longest Axles possible. 35 Spline, 40 Spline or 44 Spline axles and Series 21 (934 CV) of Series 30 CV joints are available for off Road racing, ULTRA4 Ultra 4 and Rock Bouncing - Rock Race

Proformance 4WD Trophy Truck with IFS and IRS. Our components provide much longer axles than Currie or Spider Trax Differentials. A typical Currie or Spider Trax (Spidertrax) 9 Inch or 10 Inch IFS Diff is 14 to 15 inches wide. Our Ultra Narrow Diffs are 12 Inches Narrower than a Spidertrax 10 inch IFS Diff or Currie 9 Inch or 10 Inch IFS Diff. There is simply no comparison between an ULTRA Narrow Proformance Differential and other IFS Diffs on the market today. Proformance 4WD IFS

Proformance Ultimate 4WD Trophy Truck. This machine is a bit different to traditional Trophy Trucks, with the engine in the Rear and a Diff in both the front and the rear. Combine IFS and IRS and you have many advantages over a traditional live axle rear wheel drive vehicle.

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](https://static.wixstatic.com/media/851d52_9f270a8db953421cbcaf482abdebe1e9.jpg/v1/fill/w_980,h_625,al_c,q_85,usm_0.66_1.00_0.01,enc_auto/851d52_9f270a8db953421cbcaf482abdebe1e9.jpg)
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

Proformance 4WD Trophy Truck IFS Spindle and Unit bearing. The spindle is CNC machined from a billet of 414o Chrome Moly Steel, NOT fig welded from sheet steel. There are NO WELDS in our components a at all. All the Spindle components can be field changed and are BOLTED in place rather than traditional welding.

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

Traditional Trophy Truck Fiberglass Bodies were simply not suitable. A Mid Mounted Engine, A front and Rear Diff and everything running backwards caused our team all sorts of headaches, but in the end, making our own body shell resulted in the perfect shell for our masterpiece

Proformance 4WD Trophy Truck uses a custom made Quick Change Transfer Case that reverses the direction of the engine/gearbox rotation to allow the diffs to run in the intended direction, and the rear diff driving on the Drive Side of the Diff Gear

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)
![Ultra 4 IFS IRS Suspension Mounts](https://static.wixstatic.com/media/851d52_2d56192eef604c9a924723008909503d.jpg/v1/fill/w_980,h_735,al_c,q_85,usm_0.66_1.00_0.01,enc_auto/851d52_2d56192eef604c9a924723008909503d.jpg)
Our 4WD Trophy Truck uses custom made A Arms and IFS (Independent Front Suspension) Massive Wheel Travel is achieved by using Ultra Narrow Differentials with CV Joints mounted inside the Diff Carrier. Our Proformance D60 and D80 Diffs use massive taper roller bearings to allow the CV Joints to sit inside the Diff Ring Gear.
![ULTRA4 ULTRA 4 IRS SERIES 30 CV](https://static.wixstatic.com/media/851d52_2c7b4236044442a69192e0104910254e.jpg/v1/fill/w_980,h_735,al_c,q_85,usm_0.66_1.00_0.01,enc_auto/851d52_2c7b4236044442a69192e0104910254e.jpg)
Running CV Joints inside the wheel hubs again provides longer axles. Series 21 or Series 30 Floater Hubs for Off Road racing Proformance 4WD Trophy Truck has been running narrow diff with internal CV Joints and Floater hubs for years now. We achieved 33 inches of rear wheel travel at only 22 degrees of cv angle.

Huge 934 or Series 30 CV joints can be fitted up inside the Diff Carrier to provide longer axles and more wheel travel. Using Longer Axles Allows the CV joints to run at less angle, increasing reliability.

Constructed in Perth Western Australia, Proformance Motorsport AWD (All Wheel Drive) Trophy Truck has created a stir in the motorsports arena since its release.
