These Titanium Nitride (TiN) coated shock shafts are designed as a high-performance upgrade or direct replacement for the Kyosho Optima Mid 1/10 scale buggy's suspension system. The advanced TiN coating significantly reduces friction between the shaft and the shock seals, resulting in noticeably smoother dampening action and improved suspension response over rough terrain. This enhanced lubrication not only optimizes consistent handling but also extends the lifespan of internal shock components by minimizing wear and tear. Manufactured from a durable base metal, these shafts are engineered to provide superior strength and reliability, making them ideal for competitive racing or rigorous bashing where consistent, top-tier suspension performance is paramount.
