The JAZRIDER Aluminum Rear Hubs Carrier JR-OT13 is a practical upgrade for Kyosho Optima 2016 owners seeking better rear support. Built to suit the Optima 4WD series, it provides a stronger mounting point and helps protect the rear end during demanding driving.
Using aluminium construction improves resistance to wear compared to stock plastic carriers. The design focuses on longevity and consistent fitment so hobbyists can expect fewer replacements and steadier rear performance over time.
Installation is aimed at field convenience, requiring only basic tools and a short workshop session. This makes the JR-OT13 a good choice for drivers who swap parts between practice and race days and want dependable rear stiffness without a long setup process.
