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

Aluminum front knuckles engineered for TRX-4

This JR-TRX412-GU front knuckle arms set is an RC-scale replacement part built for Traxxas TRX-4 chassis applications. Machined from aluminum with a gun metal finish, the pieces act as direct-style knuckle arms for the TRX-4 front steering assembly on scale and trail crawler rigs.

The upgrade focuses on increasing mounting stiffness and improving steering geometry retention under crawling loads. Replacing the factory plastic knuckles gives a more rigid surface for steering linkages and hubs, helping to preserve alignment during technical driving.

Installation notes: confirm compatibility with your TRX-4 steering spindle and inspect for clearance to suspension components and axle links before final tightening. Check thread engagement and ensure smooth steering travel through full lock-to-lock after installation.

Compatibility

• Designed for Traxxas TRX-4 chassis only.

Use as a replacement or upgrade on TRX-4 scale trail and rock crawling vehicles where a firmer steering mount is desired; always validate fitment and steering clearance during installation.
