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

Optima 2016 aluminum knuckle overview

This aluminium front knuckle is a scale replacement designed for the Kyosho Optima 2016 chassis. It is intended to take the place of the stock plastic knuckle and provide a firmer steering mount and more stable geometry under load, with emphasis on fitment and setup implications rather than bold performance claims.

Installation notes: the unit mounts to the same steering upright and suspension tower locations used on the Optima 2016 and matches the original bore positions. Confirm steering linkage alignment and check hex screws and ball studs for correct threads prior to final assembly. Remove the factory component carefully, align the replacement to the upright, and secure using factory hardware or equivalent fasteners of the correct thread and length.

Tuning role: fitting an aluminium knuckle changes pivot compliance, which can affect steering feedback and how the car reacts to bumps. Use this part when refining toe settings, camber link placement, or when adjusting shock valving to hone steering response without altering chassis geometry.
