SuperPro TRC6680 Steering Knuckle – Eliminate Bump Steer the Right Way
The SuperPro TRC6680 Steering Knuckle is the ultimate solution for bump steer issues affecting all 2019-onwards Isuzu D-Max, MU-X, and Mazda BT-50 models, delivering improved handling, tyre life, and alignment precision.
Isuzu and Mazda’s 2024 suspension update for the D-Max, MU-X, and BT-50 has only solved around 45% of the bump steer problem. That means drivers are still left dealing with:
- Premature tyre wear
- Inconsistent wheel alignment
- Unstable handling, especially when lifted or loaded
The SuperPro TRC6680 steering knuckle and TRC6590 upper control arm are the complete fix—engineered to reduce bump steer by up to 95%, improving handling, alignment, and tyre life, whether your vehicle is at standard height or lifted

Common Questions
Can wheel alignments fix bump steer?
No. Regular alignments might reduce tyre wear temporarily but don’t fix the core issue.
Can an upper control arm alone solve this?
No. It can help, but not enough. Designing a UCA to completely fix bump steer would create caster and clearance issues. That’s why steering knuckles are essential.
Why Bump Steer Matters
Bump steer causes your wheels to toe in or out as your suspension moves—especially with added weight or a lift kit. This leads to:
- Tyres wearing out quickly
- A steering wheel that constantly needs correcting
- Fatigue from fighting the car’s handling
