The Large Bore Valve System is the oldest of the four off-road tyre valve systems. There are three components that make up the system:
rim spud, swivel valve, and extension.

All large Bore Valves can be serviced with any of the large bore air chucks, gauges and tools found in the Haltec catalogue. As with all off-road valve systems, there are many customised products available. You will also find many customised bent extensions in use.
