The JR-TRX411-GU front C-hub kit is an aftermarket replacement for the Traxxas TRX-4 platform, finished in gun metal anodise. It replaces the plastic hubs with a metal option to reduce steering pivot flex and enhance longevity during heavy trail sessions.
Compatibility focuses on the TRX-4 layout; the hubs align with the standard TRX-4 spindle and knuckle mounting points. Most installations use the existing hardware so no bespoke adaptors are normally needed for standard TRX-4 vehicles.
Practically, metal C-hubs preserve steering geometry under load, which can change toe and caster characteristics during tight maneuvers and crawler work. Their main benefit is predictable alignment and reduced deformation after repeated impacts.
When fitting these hubs, inspect threads and bearing seats, clear any casting flash, verify suspension and linkage clearance, and torque fasteners to published specs. Applying a light threadlocker is a common practice to prevent loosening on rough trails.
