The JAZRIDER TT02-13101-LB front knuckle arms are provided as a metal alternative to the TAMIYA TT-02 plastic knuckles, with a light blue anodized finish. These aluminium components reduce flex at the wheel mounting points and are aimed at hobbyists refining steering and suspension performance.
Installation notes: they match the standard TT-02 mounting pattern and usually use the same hardware positions as the original parts. When replacing plastic knuckles, check ball stud fit and pin clearances and verify the suspension geometry after fitting.
Tuning role: aluminium knuckles deliver a firmer wheel-end connection that can enhance steering precision and repeatability, which helps during iterative setup work on toe, caster, and damping settings.
