This premium upgrade component is designed to replace the fragile stock plastic rear hub carriers on Kyosho Optima series 1/10 scale buggies, including the recent re-release and vintage models. Precision CNC-machined from high-grade aluminum, each carrier is finished with a durable gunmetal anodizing that not only enhances its aesthetic appeal but also provides superior resistance to wear and corrosion. Upgrading to these aluminum carriers significantly boosts the strength and rigidity of the rear suspension, minimizing flex and play for more consistent handling, improved power transfer, and unmatched durability crucial for competitive racing or aggressive bashing.
