Tamiya XV-01 Front Aluminum Knuckle Arms - XV01-13400-LB by Jazrider  [XV01-13400-LB]

CNC aluminum front knuckles for the XV-01

These front knuckle arms are produced as aluminum replacement parts for the Tamiya XV-01 chassis. Identified as the XV01-13400-LB set, they are intended to mount at the hub carrier and steering link locations on the XV-01 platform without altering the intended suspension geometry.

Installation follows standard front-hub service: remove the wheel and hub carrier, unfasten the steering link from the knuckle, swap the knuckle arms for the aluminum pieces, then reassemble while confirming steering geometry and clearance. Use the original screw sizes and bushings recommended by your chassis manual and verify fitment before running the car.

In tuning, aluminum knuckle arms reduce flex in the steering assembly and provide a firmer anchor for the steering link and wheel hub. That stability can deliver more repeatable steering feedback when adjusting caster, toe, or other front-end settings.
