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.
ℹ️ Alignment correction - adds - 0.5 degree camber and 1 degree caster and reduces bump steer to almost zero

Fixed offset upper control arms with heavy-duty, high-articulation ball joints and SuperPro polyurethane bushings for 1 to 3 inch lifted vehicles.
The SuperPro fixed offset upper control arm (UCA) is a high-performance aftermarket component designed to enhance the wheel alignment of lifted 4x4 vehicles, resulting in reduced tire wear and improved overall performance. This UCA is constructed using high-strength steel forgings and tube steel, making it durable and reliable for heavy-duty use. The components are robot-welded, ensuring consistent and precise manufacturing standards. The SuperPro fixed offset UCA features a heavy-duty high-articulation ball joint that enables the suspension to have greater articulation without binding, allowing for improved control and handling over rough terrain. This UCA also includes SuperPro’s renowned polyurethane bushings, which offer superior resilience and durability compared to traditional rubber bushings. The polyurethane material is resistant to abrasion, wear, and chemicals, making it ideal for harsh off-road environments.

SKU: TRC1008LBenefit Note: These arms utilise new material in the bushings and are manufactured from a high strength, light weight alloy material and come complete with a heavy duty ball joint. By eliminating the timing of the voiding of the O.E style rubber bushing, these arms have been optimised for longevity, durability and performance, without any unwanted NVH. These arms are perfectly suited as a standard replacement and are an upgrade from the factory arms, eliminating the undesirable arm movement to maintain better steering geometry in all driving conditions. In a performance lowered application, these arms offer an alternative to the SuperPro Bushings for those seeking control without further compromising the ride quality that normally is associated with lowered springs and firmer shock absorbers.
