GPM TRX-4 Front and Rear C-Hub and Knuckle Kit 6061 T6 - TRX419211322 - RC Spare Part  [TRX419211322]

Aluminum steering and knuckle upgrade

This 104pcs aftermarket kit converts the TRX-4 steering and rear knuckle assemblies to a metal-based setup aimed at RC scale trail crawling. The set groups front and rear C-hubs, inner and outer knuckle components, king pins, Delrin collars, and a full complement of stainless steel fasteners so builders can replace the factory plastic parts with aluminium alternatives while keeping the original geometry.

The kit handles steering link connections to the front gearbox, supports inner gears on both front and rear knuckles, secures the rear gearbox to the knuckle arms, and provides alternate lower damper mount positions so you can alter shock height and angle for tuning.

Adjustment options are preserved: the damper lower eye can be secured in different holes to change ride height and damper cant. Stainless steel king pins replace plastic originals and Delrin collars are fitted to reduce play between rotating parts.

Use this kit when you want a metal upgrade path for TRX-4 scale trail builds while retaining the stock layout; the parts give alternate damper mounts, metal king pins, and Delrin collars to reduce play.
