Traxxas TRX-4 Aluminum Front Knuckle Arms by JAZRIDER JR-TRX412-BK  [JR-TRX412-BK]

Aluminum front knuckle arms for TRX-4

This is an RC-scale front knuckle arm upgrade designed for Traxxas TRX-4 vehicles. The JR-TRX412-BK replaces the stock front knuckle arms with machined aluminum components intended to increase wear resistance and maintain steering geometry under trail and scale crawling loads.

The parts are presented as a like-for-like replacement for TRX-4 mounting points, so no chassis modifications are expected beyond standard knuckle removal and reassembly. The alloy construction focuses on dimensional stability and repeated-use durability compared to typical molded alternatives.

For tuning and setup the knuckle arms play a role in steering feel and response; users often assess toe and draglink alignment after installation and verify there is no binding through full suspension travel. These components integrate with the existing TRX-4 steering linkage and wheel hub interfaces when fitted to compatible units.

Use this aluminum front knuckle arm set when seeking a durable, dimensionally stable replacement for TRX-4 front steering components, especially for scale trail and technical crawling where steering precision and longevity matter.
