Superpro Bump Steer Correction Kit - Gen 3 Isuzu D-Max RG, Gen 3 Mazda BT-50 & Gen 2 Isuzu MU-X

Steering Knuckle Kit - Bump Steer Correction.

The New Isuzu D-Max, MU-X & Mazda BT-50 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.

These brand-new steering knuckles resolve the issue and are suitable for both standard height and lifted vehicles.

Many People even with Standard Height Vehicles that tow Caravans or Trailers are seeing rapid tyre wear when towing

When these knuckles are installed in a standard-height vehicle, the bump steer is reduced to almost zero.

For raised vehicles, combine a pair of Superpro steering knuckles with a set of Quality Aftermarket upper control arms in your raised vehicle and you will solve your premature tyre wear, sort your alignment issues and have your vehicle driving well as intended.

Sold as a Left and Right Knuckle Kit is designed to optimise the steering geometry, reduce the inherent factory bump steer to almost zero and decrease tire wear drastically.

The Superpro steering knuckles replicate all the features of the original equipment (OE) knuckles and come with identical mounting provisions for a seamless direct replacement.

It is produced using a hot forged 4140 AISI steel which is then post machined, heat treated and finished in black e-coat for maximum for corrosion protection.

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 a good Aftermarket Upper Control Arm would reduce a further 10-15%.
