Front steering-knuckle correction kit for late-model Isuzu D-Max, MU-X and Mazda BT-50.

The SuperPro TRC6680 kit changes the steering-rack pickup geometry at the knuckle to reduce bump steer, inconsistent alignment and premature tyre wear. It suits standard-height and raised vehicles and is designed as a direct OE-style replacement without chassis modification.

The paired knuckles are manufactured from hot-forged 4140 AISI steel, post-machined, heat-treated and finished with a black e-coat for corrosion resistance. SuperPro states that the design is VSB 14 approved, ADR compliant and FEA tested to a 1650 kg front axle load.

Key features

• Corrects front bump-steer geometry
• Suitable for standard height and approximately 30–50 mm raised vehicles
• Direct replacement using the vehicle’s existing hubs, seals and related hardware
• Hot-forged 4140 AISI steel construction
• Includes left and right steering knuckles

Fitment

Fits applicable Isuzu D-Max 2019/2020-on, Isuzu MU-X 2021-on and Mazda BT-50 2020-on models. Professional installation and a post-fit wheel alignment are required. For a raised vehicle, SuperPro recommends pairing this kit with TRC6590 upper control arms for the greatest geometry correction.
