This 3-piece flywheel nut assembly is precision-machined from durable steel for reliable engagement with SG-shaft crankshafts commonly found in Kyosho nitro engines. Its robust construction ensures a secure connection to the flywheel, preventing slippage under high RPM and heat, which is critical for consistent engine starting and smooth power delivery. This component is essential for maintaining optimal engine performance and preventing drivetrain damage in nitro-powered RC vehicles.
