TRAXXAS TRX4 Trail Crawler Aluminum Front+Rear C-Hub and Knuckle Set by GPM TRX419211322  [TRX419211322]

Aluminum front and rear steering components

This 104pcs aftermarket kit converts the TRX-4 steering and rear knuckle assemblies to a metal-based setup intended for 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 aluminum alternatives while keeping the original geometry.

Key functional roles covered by the kit include linking the front gearbox to the knuckles within the steering assembly, stabilizing inner gears on both front and rear knuckles, securing the rear gearbox to the knuckle arms, and providing alternate damper lower-mount positions to change damper height and angle for tuning.

Adjustment is retained: the damper lower eye can be fixed into different hole positions to alter ride height and the damper cant. The kit supplies stainless steel king pins to replace plastic originals and Delrin collars pre-installed to reduce play between rotating parts.

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