Valves

Valves control the flow and pressure of air or fluid in key truck systems, helping your commercial truck brake, ride level, and operate safely. Our selection covers common needs like air brake valves and quick release valves, hand and trailer hand valves, cab leveling valves, and even related parts like heavy duty tire valve stems and valve stem extensions for easier inflation and better sealing. Because correct fitment matters, we help match parts to your truck’s make and model, the system type (air brake, suspension, hydraulic), and details like port size, thread type, and mounting style, so you get the right valve for Freightliner and other top brands without guesswork.
