This aluminium front C-hub kit has been produced for the Traxxas TRX-4 platform and is identified by JR-TRX411-BK. It replaces the original plastic hubs to deliver a sturdier steering mount and improved repeatability during technical driving.
Install as a direct-fit to TRX-4 mounting points but always confirm alignment with your knuckles and steering linkage. Because the component is metal, verify screw torque and steering clearance before first use and follow common RC fastening practice to protect threads and mating hardware.
Swapping to aluminium reduces local compliance at the hub interface, helping hold steering geometry under load and producing a more predictable steering response. Expect to re-check toe and steering endplay after fitting and adjust trims or link positions as necessary to suit your setup.
