This conversion set provides a significant upgrade for the steering system of Kyosho Optima re-release series vehicles, replacing the standard plastic servo saver with a robust, precision-machined metal assembly. Crafted from durable aluminum alloy, often finished with a distinctive anodized coating, it vastly improves steering response and offers superior protection for your servo's internal gears against impacts and stress during aggressive driving. RC enthusiasts seeking enhanced reliability and a more precise feel on the track or trail will find this conversion an essential modification to withstand the rigors of high-performance off-road action.
