Precision machined front knuckle for TRAXXAS GT4 TEC 2.0

The GT021 front knuckle arm is engineered as a CNC machined replacement to interface with steering tie rods and deliver repeatable steering geometry on TRAXXAS GT4 TEC 2.0 4WD platforms. Manufactured from 6061 T6 aluminium, the component prioritises dimensional stability and reduced deflection under lateral loads.

Supplied as a 2pcs set to replace standard plastic knuckles, the GT021 is finished with a hard-anodize available in multiple colours to enhance surface wear resistance while maintaining tolerances. Tight machining controls are employed to keep steering ackermann and wheel alignment consistent once installed.

Use this component for track-focused setups where predictable steering feedback and sustained geometry are required. The installation is a direct replacement using the OEM mounting points and hardware; final checks of linkage length, toe and camber are recommended to ensure optimal handling.

Parts are very nice. Fit very well. Easy to install. But screws are sometimes to short. And piece was not drilled and tapped deep enough. But overall excellent workmanship. Your shipping leaves a lot to be desired. And it seems tha you got a little confus

What tolerances are targeted during machining?

Machining targets tight concentricity and hole positional tolerances to preserve steering ackermann and minimise alignment shifts compared with molded plastic parts.

How does material selection affect fatigue life?

6061 T6 delivers superior fatigue resistance under cyclic loads relative to common engineering plastics, which reduces dimensional drift and helps maintain geometry over time.

Are finish options functional or cosmetic?

The hard-anodized finish is primarily protective, offering improved surface hardness and wear resistance while being applied thinly enough to preserve dimensional fit with mating parts.
