The XRAY 305070 Composite Differential Locknut Set is designed to hold external ball diff settings firmly and shield the internals from dirt and debris. These locknuts are useful for drivers who want consistent diff behaviour across runs.
Beyond clamping the adjuster screw, the composite cap acts as a barrier to contaminants, helping to preserve bearing and ball condition in the differential. That protects performance on loose or dusty surfaces.
The composite material gives a sensible compromise between strength and weight, making these locknuts suitable for drivers trimming every gram from their setup without losing durability.
