The AccuAir SwitchSpeed™management kits offer all of the standard functions that you’ve come to expect from a traditional switchbox, but that’s where the similarities stop. AccuAir’s proprietary Advanced Burst-Control-Technology™ allows you to choose between three different modes of adjustment; precise, moderate, and full speed. The burst speeds for each of these modes are user-tunable to achieve improved precision from even the largest valves on the market. All of our full air ride kits are engineered to improve ride quality, increase performance and add maximum height adjustability. Now you can get over those annoying speed bumps while still retaining the ability to roll as low as possible.

Description of the VU4-Corner Valve Unit:

The AccuAir VU4 4-Corner Valve Unit is engineered to provide the cleanest installation and most reliable operation on the market. This electronic solenoid valve unit inflates and deflates up to (4) individual Air Springs and has built-in push-to-connect 3/8” D.O.T. approved air fittings for all of it’s plumbing connections. The robust internal solenoid valve architecture maximizes flow rates, provides bubble-tight sealing, and guarantees operation up to 200 psi for millions of cycles. All of this technology is housed in a unique enclosure design which routes each of the solenoid wires to a single weatherproof connector, eliminating typically loose wires. This not only improves the appearance, but it also guarantees proper operation for every installation. With an overall size of only 5”x 3”x 3” and the ability to survive harsh under vehicle environments, this product is ideal for any application.


Features of the VU4-Corner Valve Unit:

- Pre-wired & port numbered for reduced installation time

- 3/8" push-to-connect D.O.T. fittings eliminate pipe threads for 100% leak free operation

- Dual inlet & exhaust ports for maximum flow (plug extra inlet if not required)

- Compact layout for minimal space usage

- Four built-in 1/4" gauge/sensor ports

- Anodized aluminum manifold to prevent corrosion

- 100% weather resistant for harsh under vehicle environments
