Tenneco Inc. | Monroe Shocks and Struts | Hydraulic vs. Gas Charged Shocks
Depending on the application, some units have high hydraulic control and lower gas pressure, low hydraulic control and lower gas pressure or no gas pressure at all. The hydraulic part of the shock is what provides performance while the gas portion allows hydraulic fluid to perform more consistently. Tenneco offers the right hydraulic control and gas pressurization for each application, delivering the correct ride profile for that vehicle.
Most shocks and struts are designed to function in a vertical or up and down position. However, before they are installed, they are generally stored on their side. Prior to installation, it is important to prime the shocks or strut. How to prime units can be found at 3:35. (Video — Tenneco Inc.)
