The JR-TRX411-GU front C-hub kit is an aftermarket aluminium option for the Traxxas TRX-4 chassis finished in gun metal. It replaces plastic hubs to reduce steering pivot flex and improve resistance to wear over time.
These hubs are produced to align with the TRX-4 knuckle and spindle mounting points and are intended to be used with the stock TRX-4 hardware in typical installations. No special adaptors are required for standard fitment.
Switching to aluminium hubs helps stabilise steering geometry when under load, which can affect toe and caster during tight maneuvers and slow crawling. The goal is consistent alignment and reduced deformation for reliable trail performance.
Before installation clean mating surfaces, remove any burrs, check bearing fit and clearances with suspension and steering links, and torque fasteners to the vehicle manufacturer's specifications. A mild threadlocker is often recommended for fasteners exposed to repeated shock.
