The JAZRIDER JR-OT01 front knuckles are a straightforward aluminium replacement designed for the Kyosho Optima 2016. They reduce flex compared to stock plastic parts and give a more stable front end for routine driving and hobbyist use.
Aluminium offers improved impact resistance and longer service life, lowering the frequency of part swaps. For day to day running the result is steady steering feel and fewer interruptions for repairs.
Manufactured to match the Kyosho Optima 2016 mounting points, the JR-OT01 set installs with standard RC tools. This makes the upgrade accessible to most hobbyists without special machining or adapters.
