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.

When lifting a vehicle, the Constant Velocity (CV) joints are put on an increased angle, helping to accelerate the wear on the joint and putting additional stress on the CV boots. The added down travel from adding extended shocks can also cause the joint to exceed the maximum operating angle, which causes the CV joints to bind up and cease to operate. The SuperPro bolt-on kit corrects the geometry of the front axles and CV's by lowering the front diff approximately 25mm. Reducing the angles on the CV joints can help get them back into the normal operating range, helping to avoid the expensive replacement costs of CV's.
This bolt on kit corrects the geometry of the front axles and reducing CV bind at full droop by lowering the front diff approximately 20mm. This kit requires no modifications to the cross member and allows the original bash plate to be refitted.

Fully Customisable & Rebuildable
The Formula F4R Shock is a 3-way adjustable remote reservoir coil-over system in the front and a 2-way adjustable remote reservoir shock in the rear, specifically designed to suit your vehicle. The damper uses Fulcrums own high flow digressive piston with carefully chosen shim stacks to create the best damping characteristics for each vehicle.
The front damper is 3-way adjustable, spring pre-load, compression bypass and rebound bypass. The rear damper is 2-way adjustable, compression bypass and rebound bypass.
The adjustment clickers allow the user to carefully control how much oil is allowed to bypass the shim stacks in each direction. Opening the clickers allows more oil to bypass, reducing the damping effort in either compression or rebound. This allows tuning for different load scenarios and road conditions.
This Formula F4R Adjustable Remote Reservoir Kit is preset to:
50mm or 2"
