Westar Suspension Solenoid

Westar Suspension Solenoids: Precision Air Flow Control for Your Vehicle

When an air suspension system loses its ability to self-level or maintain ride height, a failed suspension solenoid is often the culprit. As the electromechanical “gatekeeper” of your vehicle’s air suspension, the solenoid valve regulates how air flows into and out of the air bag — and a worn or defective one can bring the entire system to its knees. Westar has built a focused reputation in this space, offering purpose-engineered replacement solenoids as part of its broader suspension solenoid lineup.

Why Westar in the Suspension Solenoid Category?

Founded in 1986 and headquartered in Maryland, Westar Distribution has grown from a small warehouse operation into a nationally recognized aftermarket air suspension specialist. Their suspension solenoids are designed to meet or exceed OEM specifications on quality, fit, and function — a standard Westar applies across every product they manufacture. All components are produced to strict ISO, QS, and TS industry standards, with each unit subjected to real-time load testing to verify machine endurance and catch any factory defects before a part reaches a vehicle.

Westar’s solenoid valves are engineered around how these components actually work in the field. Suspension solenoids can be mounted in one of three configurations: directly on the air bag, on a separate block within the air line, or integrated into the compressor assembly. Westar’s product lineup accounts for all three installation types, ensuring the replacement matches the vehicle’s original routing and mounting setup precisely.

Product Lines & Vehicle Coverage

Westar’s suspension solenoid catalog includes part numbers such as the SO-7590 and SO-7593 air spring solenoids, as well as solenoid valve units in the CV-series (including CV-0004, CV-0009, and CV-0012). These parts cover a wide range of domestic and import applications — from the 2007–2012 Lincoln Navigator to vehicles from Ford, GM, Audi, BMW, Jaguar, Land Rover, Mercedes-Benz, and Volkswagen. With over 200 active part numbers in the air suspension category and new numbers added regularly, Westar continues to expand fitment coverage across the most common air-suspended passenger cars and light trucks.

All Westar air suspension products, including their suspension solenoids, are sold as 100% new units — not remanufactured — and are backed by a 12-month / 12,000-mile limited warranty. For drivers and technicians who need a reliable, OE-quality solenoid without the dealership price tag, Westar represents a well-established choice in the aftermarket.
