We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It isolates the primary and secondary air circuits, ensuring that a leak in one circuit does not deplete the other, so you always have some braking capability. It opens at a preset pressure to allow air to flow into a secondary system and closes when pressure drops, protecting the primary system. Usually replaced when it fails to hold pressure, leaks externally, or does not open/close within specification.
