TRX-4 Trail C-Hub and Knuckle Set Aluminium 6061 T6 - TRX419211322 by GPM  [TRX419211322]

6061-T6 C-hub and knuckle upgrade for trail use

This 104pcs aftermarket kit converts the TRX-4 steering and rear knuckle assemblies from plastic to a metal-focused setup intended for scale trail use. The package includes front and rear C-hubs, inner and outer knuckle halves, king pins, Delrin collars, and a full set of stainless fasteners so you can swap out original plastic components while retaining the stock layout.

The components perform key roles: linking steering to the front gearbox, supporting inner gears on knuckles, anchoring the rear gearbox to knuckle arms, and providing alternative damper lower-mount positions so you can tune shock height and cant.

You keep adjustability: the damper lower eye can be fixed in various holes to change ride height and damper angle. Stainless king pins replace the factory plastic items and Delrin collars limit play at rotating interfaces.

Fit this conversion for a stronger metal steering and knuckle setup on TRX-4 scale rigs while keeping stock geometry; extra damper mounts, stainless king pins, and Delrin collars help reduce play and fine tune handling.
