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

Precision machined TRX-4 knuckles

This JR-TRX412-GU front knuckle arms set serves as an RC-scale replacement crafted for Traxxas TRX-4 chassis use. CNC-machined from aluminum with a gun metal finish, the parts are made to act as direct-fit knuckle arms for the TRX-4 front steering assembly on scale trail rigs.

The objective of the design is to provide consistent steering geometry and enhanced durability during slow-speed crawling. Replacing the stock plastic knuckles gives a firmer mounting surface for steering links and hub components, aiding repeatable alignment across technical obstacles.

Installation notes: confirm spindle interface on your TRX-4 and check for clearance with adjacent suspension links and axle components before final torque. Verify thread engagement and test full-range steering movement after fitting.

Compatibility

• Designed for Traxxas TRX-4 chassis only.

Intended as a replacement or upgrade for TRX-4 scale trail and rock crawling builds where a more rigid steering mounting point is desired; always validate fitment and steering clearance during installation.
