Kyosho Optima 2016 Steering Knuckle Upgrade JR-OT01 by Jazrider  [JR-OT01]

Precision aluminium steering knuckle for Optima 2016

This aluminium replacement knuckle is designed specifically for the Kyosho Optima 2016 chassis and replaces the original plastic unit to provide a more rigid steering mount and steadier geometry under load. The write up concentrates on compatibility, fitment approach, and tuning function rather than bold performance claims.

Installation notes: the part mounts to the same upright and suspension tower points used on the Optima 2016, keeping original bore spacing. Before final tightening, check steering link connections and confirm hex screw and ball stud thread sizes. Carefully remove the factory item, align the new knuckle to the upright, and fasten with the factory hardware or suitable equivalents that match thread and length.

Tuning role: swapping to an aluminium knuckle alters pivot flex characteristics and can change steering feedback and response to bumps. Use this upgrade when experimenting with toe settings, camber link placement, or different shock valving to fine tune steering feel while retaining chassis geometry.
