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

Front knuckle arm replacement for XV-01

This aluminium front knuckle arm set is intended specifically for the Tamiya XV-01 chassis and carries the part designation XV01-13400-LB. The components occupy the steering knuckle positions and serve the wheel hub and steering link mounting functions on the XV-01 platform.

Installation steps include removing the wheel and hub carrier, disconnecting the steering link, replacing the knuckle arms and reassembling while verifying steering geometry and rotor clearance. Reuse the original screws and bushings where appropriate and confirm fitment before driving.

In competitive tuning, aluminium knuckles are selected to cut flex in the steering system and provide a more rigid connection for the steering link and wheel hub. That stiffness can make steering feedback more consistent when making fine adjustments to caster and toe settings.
