The Bendix Relay Valve, part number 800305, is a genuine Bendix brake system component for heavy-duty truck air brake systems. Relay valves control brake chamber response by delivering and exhausting air pressure locally at the axle, reducing brake lag on longer wheelbase vehicles and trailers. This part is sold by Pro Gear and Transmission. Call us to confirm proper fitment for your specific vehicle and brake system configuration before ordering.
A factory handling fee of $20.00 per unit is added at checkout.
