The Kyosho UM510-01 is a purpose-made 62.5mm swing shaft built to suit the RB5 chassis, providing dependable performance for club and competitive use. It is a practical spare for runners who need consistent handling and minimal drivetrain lash.
With careful machining and robust material choice, this swing shaft resists wear and keeps the car feeling stable through corner exits. Its design helps deliver predictable power transfer under braking and acceleration.
Built to integrate with RB5 setups, the UM510-01 also pairs with many LAZER series parts, making it a useful component when refreshing drivetrain pieces on a raced car.
