This premium upgrade set is engineered to replace the standard plastic servo saver assembly found in Kyosho's iconic Optima series of 1/10th scale buggies and trucks. Crafted from high-grade, CNC-machined aluminum, it offers significantly enhanced durability and rigidity over the stock component, effectively minimizing flex and improving steering precision during aggressive driving. Integrated precision ball bearings further refine the steering linkage by reducing slop and friction, providing smoother operation and extending the lifespan of your steering servo by absorbing impactful forces from landings and collisions.
