Is your vehicle showing signs of worn-out struts such as poor ride control and handling, fluid leaks, suspension noise, and a variety of steering problems? If you’ve observed or experienced most of these signs, it’s time to take a look at your vehicle’s struts. Once you’ve confirmed that the culprit behind these car problems is a worn-out strut assembly, replace it as soon as you can. But before you grab the first strut kit you see, you need to know first which type will suit your vehicle and needs best. To help you on this, here’s the lowdown on the two basic types of strut assemblies:
As its name suggests, this assembly uses two tubes or cylinders—inner and outer. The inner cylinder, also known as the working cylinder, is where the shaft and piston are located. The outer cylinder, on the other hand, functions as a hydraulic fluid reservoir. This strut design involves several valves that offer additional damping force and control the flow of fluids between the two cylinders. A twin-tube assembly is used on a variety of non-performance vehicles as a factory built kit. So if you’re looking for a replacement strut assembly for your car’s factory struts, a twin tube type is a good choice.
A monotube assembly features a single tube or cylinder. This cylinder is then divided into two parts: a gas chamber and a fluid chamber. The fluid chamber is similar to a twin tube’s inner cylinder this is where the piston and shaft move up and down. Compared to a twin tube, a monotube has a larger diameter. To separate the monotube’s two parts, a seal and floating piston is used. Because of its design, this type of strut assembly offers a more aggressive movement. This is why this design is included as a factory kit on certain performance and racing vehicles. It’s also the perfect kit if you wish to upgrade a suitable vehicle that originally came with twin tube struts since it offers higher performance capabilities. However, before you upgrade to a monotube assembly, make sure first that your vehicle’s suspension system can handle more aggressive struts.
