Unit bearing trucks require a reliable way to keep the axle shafts fully engaged—especially under heavy throttle or high impact trail conditions. OEM locking hubs are known to fail when pushed hard. A drive flange kit eliminates that weak link, providing a direct mechanical connection between the wheel hub and the axle shaft at all times.
Crane’s design uses an alloy steel slug for unmatched strength and pairs it with a lightweight yet durable aluminum cap. This ensures a dependable interface that survives high torque, high-RPM abuse common in rock bouncing and aggressive trail riding.
