Standard Senior Axle Keys

Precision Standard Senior Axle Keys are precision-machined keyways designed to lock the axle to the sprocket carrier and other rotating components on senior karts, available in 2-pin 34mm (compatible with OTK), 3-pin 34mm (compatible with KR) and 2-pin 30mm fitments. Manufactured to tight tolerances for a secure, reliable fit that resists shearing under the loads of racing, they're an essential maintenance item for keeping your drivetrain properly located. A small part that plays a big role in transferring power safely and consistently to the wheels.
