TRX-4 Scale C-Hub and Knuckle Upgrade 6061 T6 - TRX419211322 by GPM  [TRX419211322]

Metal front and rear steering components

This 104pcs aftermarket kit converts the TRX-4 steering and rear knuckle assemblies into a metal-based package suited to RC trail crawling. The complete set groups front and rear C-hubs, inner and outer knuckle parts, king pins, Delrin collars, and an extensive set of stainless fasteners so builders can swap out the factory plastic pieces for aluminium without changing basic geometry.

Functionally the kit links the front gearbox to the knuckles, stabilises inner gears on both front and rear knuckles, secures the rear gearbox to knuckle arms, and offers extra lower shock mount holes to vary damper height and cant for tuning.

Adjustment features remain: the damper lower eye can be secured in alternate positions to alter ride height and shock angle. Stainless king pins replace plastic items and Delrin collars are used to reduce rotational play.

Fit this aluminium conversion to add metal C-hubs and knuckles to TRX-4 builds while preserving factory geometry; the kit supplies different damper lower mounts, metal king pins, and Delrin collars for reduced slack.
