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

Front knuckle arms for XV-01

This is an RC-scale aluminum front knuckle arm set designed around the XV-01 naming, supplied under the JAZRIDER JR-XV100-GU designation. The component is intended as a direct-style replacement or hop-up for XV-01 steering assemblies where alloy knuckles are preferred to stock plastic for increased rigidity and consistent steering response.

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

From a tuning perspective, aluminum knuckles alter feedback and can reduce flex under load, which affects steering precision and camber stability during aggressive driving or suspension changes. When swapping to alloy knuckles, re-check toe and camber settings and verify that suspension articulation remains free of binding across the steering travel.
