Bump Steer Correction Kit – RD-DMAX01
This kit corrects factory steering geometry across the full suspension travel for both standard and lifted 2021+ Isuzu D-MAX, MU-X, and Mazda BT-50 vehicles.
By reducing excessive bump steer by up to 40%, the kit helps prevent premature and uneven tyre wear while significantly improving steering response. Reduced steering effort minimises driver fatigue, delivering safer, more precise vehicle control—particularly on rough or uneven roads.
Constructed using polyurethane bushes with aluminium crush tubes, the kit repositions the steering rack to its optimal height while preserving ride quality and full ADR compliance.
Key Benefits

-
Optimises steering geometry throughout the full suspension range
-
Improves vehicle control on-road and off-road
Reduces Bump Steer
-
Up to 40% reduction in bump steer
-
Minimises uneven tyre wear and extends tyre life
Durable Construction
-
Polyurethane bushes with aluminium crush tubes
-
Lowers the steering rack to the optimal position without increasing NVH
ADR Compliant
-
Engineered to maintain Australian Design Rule (ADR) compliance
-
No added steering vibration or harshness
What Is It?
The RD-DMAX01 is a bump steer correction (rack drop) kit designed to address a known steering geometry issue in 2019-onwards Isuzu MU-X, D-MAX, and Mazda BT-50 models. Correcting this geometry improves tyre longevity and reduces driver fatigue, especially on rough road surfaces.
How Does It Work?
The kit replaces the factory steering rack mounting bushes with offset polyurethane bushes, lowering the steering rack to a more optimal position. This correction reduces bump steer without increasing noise, vibration, or harshness (NVH), ensuring continued ADR compliance.
Installation Requirements
-
Suitable for installation by a qualified wheel alignment workshop
-
Approximate fitting time: 3 hours, including wheel alignment
-
Vehicle must be aligned to OE specifications:
-
Castor: 3.2°
-
Camber: 0°
-
Toe: ±0.5 mm
-
ADR Compliance
The RD-DMAX01 is fully ADR compliant. To maintain compliance:
-
All soft mounts in the steering system must be retained
-
No rigid mounts or additional steering loads may be introduced
Engineering Certification
No engineering certificate is required. The kit utilises OE-style soft bushes and does not increase NVH, ensuring continued ADR compliance.
Performance Improvement
-
Reduces excessive bump steer by approximately 40%
-
Improves steering feedback and proportional tyre wear reduction
Vehicle Applicability
-
Isuzu D-MAX & Mazda BT-50: July 2020 onwards
-
Isuzu MU-X: June 2021 onwards
While 2025 facelift models feature a factory reduction in bump steer, further improvements in tyre wear and drivability can still be achieved with this rack drop kit.
Do I Need Full Knuckle Replacement?
While complete bump steer correction via replacement knuckles is possible, it is often cost-prohibitive. Reducing bump steer by 40% using this rack drop kit offers a significant improvement in handling and tyre wear at a realistic price point.
Important Notice
Do not combine bump steer correction components from multiple brands.
