SuperPro Upgraded Front Steering Knuckle Kit - Bump Steer Correction to suit Isuzu D-Max, MU-X & Mazda BT-50 (Fixes Tyre Wear)

• Vastly improved handling and overall vehicle dynamics (building driver confidence and supporting the fact that the car just feels a whole lot better)
• Improved stability (day-to-day driving as well as touring/off-roading)
• The driver will not have to constantly correct the steering (or fight lane change assist)
• Less driver fatigue meaning higher levels of concentration and reduced chance of being involved in an accident
• And finally, reduced tyre wear meaning better contact between the tyre and the road

The Isuzu D-Max, MU-X & Mazda BT-50 can suffer from chronic bump steer resulting in radically increased tyre wear which is apparent in standard height vehicles, but becomes more prominent as you lift them.

Can Regular Wheel Alignments from a Suspension Specialist Fix this issue?
You could get a wheel alignment from a suspension specialist every 5000km and rotate your tyres every so often to help reduce tyre wear. But this only mitigates the issue it is not a fix. Doing regular wheel alignments serves as a band aid fix to the actual problem.

Alternative fixes that are NOT a Steering Knuckle...
The issue with just doing an upper control arm is you cannot get enough offset in an upper control arm to get a corrective fix for bump steer. The steering rack pickup point needs to be raised to fix the issue. A UCA (upper control arm) can get some change to help with bump steer but wont fix the issue.

If an upper control was designed to fix the bump steer issue you would end up with so much caster that you would end up with tyre clearance issues, giving your car a new problem.

Why is bump steer an issue?
Bump steer is the change in toe in or toe out as the ride height of the vehicle changes. This occurs constantly when driving as the vehicle oscillates over the bumps in the road. This movement is magnified by increased weight from towing, high loads, accessories or a suspension lift . An excessive amount of bump steer will cause extreme amounts of premature tire wear, which is what field reports have shown to the development team first-hand and through their own R&D testing.

What does the SuperPro steering knuckle do to help?
The SuperPro steering knuckle relocates the outer tie-rod pickup point to better optimise the steering geometry of the vehicle to reduce the amount of bump-steer at a range ride of heights. The graph below shows the bump steer reduction when the SuperPro steering knuckles are fitted to a lifted vehicle. The bump steer is reduced by about 75% overall, which when combined with the Zeder offset FUCA would reduce a further 10-15%. When the knuckles are installed in a standard-height vehicle, the bump steer is reduced to almost zero.
