The SuperPro TRC6680 Steering Knuckle is the complete fix for bump steer on all 2019+ Isuzu D-Max, MU-X, and Mazda BT-50 models. Isuzu and Mazda's 2024 suspension update only addressed around 45% of the bump steer problem — the TRC6680 eliminates up to 95% of it by fixing the actual cause: raising the steering rack pickup point.

Why the TRC6680?

  • Fixes the root cause of bump steer — upper control arms alone cannot do this
  • Reduces tyre wear and improves road contact
  • Enhances driving stability, comfort, and safety
  • Suitable for standard and lifted vehicles
  • Direct OE-style fitment — no modifications required

What's Included

  • SuperPro TRC6680 Front Steering Knuckle Kit — Bump Steer Correction
  • Professional Installation at our workshop
  • Wheel Alignment

Construction & Compliance

  • Hot-forged 4140 AISI Steel, heat-treated and black e-coated
  • Tested to 1,650kg front axle loads using FEA analysis
  • VSB14 Approved — no engineer sign-off or mod plate required
  • ADR Compliant — meets OE design standard
  • Suitable for use with any GVM upgrade

Professionally Installed: $2,637.00
