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

Aluminum front knuckle arms for TRX-4

This JAZRIDER JR-TRX412-GU front knuckle arms set is an RC-scale replacement part made for Traxxas TRX-4 chassis use. Machined from aluminum with a gun metal finish, the components serve as direct-style knuckle arms for the front steering assembly on TRX-4 scale and trail crawlers.

The part focuses on chassis durability and steering geometry consistency under crawling loads. In practice it replaces the stock plastic knuckles to provide a rigid mounting surface for steering linkages and hub assemblies, helping to maintain alignment during low-speed technical driving.

Installation considerations: verify fitment to the TRX-4 steering spindle and check clearance against suspension components and axle links before final tightening. Inspect thread engagement and any mating hardware for wear, and confirm smooth steering travel through full lock-to-lock movement after installation.

Compatibility

• Designed for Traxxas TRX-4 chassis only.

Use as a replacement or upgrade for scale trail and rock crawling setups on TRX-4 vehicles where a firmer steering mount is preferred, while confirming fitment and steering clearance during installation.
