One. Solid. Block.


Our V8-200 is manufactured with premium aluminum alloy, bringing durability and quality. Our objective with this unity is to provide the maximum efficiency and command response. And we did it!


The Solenoid is literally the heart of the air valve system. It controls the system air flow that enters amd the the air that is exhausted from the system. So every time you command the air system to raise or lower, the system will respond perfectly with any of the 8 valves that enable the individual corners, also, the various selection of colors add sophistication and premium quality to an already highly engineered product.


When you combine the best material with a system that works flawlessly, the result can only be one thing: exceeded expectations.
