MONOTUBE SHOCK TECHNOLOGY
AST's monotube design translates into a bigger piston. When you put AST shocks on your car, you know that those big pistons can handle much larger loads. This translates directly into the ability to fine tune your shock. Other shocks that use twin tubes have much smaller pistons; and that means less ability to handle performance loads and less flexibility when it comes to adjustments.
These are high-pressure gas shocks with only one tube, the pressure tube. Inside the pressure tube there are two pistons: a dividing piston and a working piston. The working piston and rod are very similar to the twin tube shock design. The difference in actual application is that a mono-tube shock absorber can be mounted upside down or right side up and will work either way. In addition to its mounting flexibility, mono-tube shocks are a significant component, along with the spring, in supporting vehicle weight.
