Here is a comparative look at Maximum’s Sport Series front strut (left) and the Tokico drag strut (right). Notice the difference in thickness? The road-race strut is larger due to its inverted-piston, monotube design (the fluid is in the upper, polished portion), which provides lower unsprung weight for improved handling. The piston-housing’s large diameter and bushings that separate the strut’s inner and outer tubes reduce friction, and greatly improve the strut’s resistance to bending during cornering. By contrast, the Tokico strut is a twin-tube design, having two concentric tubes that are separated by oil (the piston is mounted to the hollow strut shaft, which comes down from the top).
