TAMIYA XV01 Alloy Rear Knuckle Arm by GPM XV022  [XV022]

Aluminium rear knuckle for XV-01

This is an aftermarket alloy rear knuckle arm produced by GPM for the TAMIYA XV-01 chassis. Designed as an RC-scale replacement for the stock rear knuckle arm, the part focuses on improving durability and offering a firmer mounting point in the rear suspension and steering linkage area without altering basic geometry.

Material choice and construction: the arm is described as alloy, intended to resist wear compared with typical plastic components used in stock assemblies. Installation is intended to use the XV-01 rear knuckle mounting points; verify fit and fastener compatibility before final assembly on your model.

Tuning role: fitment of an alloy rear knuckle arm is commonly part of chassis upgrade paths aimed at reducing flex at the rear upright, enabling more consistent rear-end response during setup changes such as roll centre adjustments, camber link length, or shock mounting tweaks on 1/10 touring car setups.
