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.

Why TRC6680?

Fixes the real cause of bump steer by raising the steering rack pickup point—something upper control arms alone can’t do

Reduces tyre wear and improves contact with the road

Enhances driving stability, comfort, and safety

Suitable for standard and lifted vehicles

Direct OE-style fitment – no modifications required
Manufactured from hot-forged 4140 AISI steel, heat-treated and black e-coated for durability and corrosion resistance.

Legal & Fully Compliant
✅ VSB14 Approved – No engineer sign-off or mod plate needed
✅ ADR Compliant – Meets OE design standards
✅ Tested to 1650kg front axle loads using FEA analysis
✅ Suitable for use with any GVM upgrade
This product installs just like a control arm, spring, or shock—simple and legal.

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

Proven, Tested, Trusted
The TRC6680 has been tested by SuperPro’s engineers and independent assessors to exceed strength and compliance standards. It’s built to perform and last.
Pair it with the TRC6590 upper control arm to fully restore proper geometry and feel the difference immediately.
