TAMIYA XV-01 Front Knuckle Arms Aluminum Upgrade - JR-XV100-GU by Jazrider  [JR-XV100-GU]

XV-01 alloy front knuckles

This RC-scale aluminum front knuckle arm set is designed for the XV-01 platform and is identified by the JR-XV100-GU model number. The component works as a direct-style replacement or hop-up for XV-01 steering assemblies where alloy knuckles are preferred over stock plastic to increase rigidity and deliver more consistent steering response.

Installation follows standard XV-01 steering geometry and uses the original mounting points and hardware from the chassis. Expect straightforward fitment: transfer existing pivot balls, spacers, and any applicable bearings from the stock knuckles. The alloy construction and gun metal finish focus on mechanical stiffness and wear resistance rather than visual modification.

From a setup standpoint, aluminum knuckles change feedback and can reduce flex under load, which alters steering precision and camber stability during aggressive driving or suspension changes. After swapping to alloy knuckles, recheck toe and camber and confirm that suspension articulation is free of binding through full steering travel.
