In one embodiment, an impact-absorbing shock module comprises two pylons telescopingly engaged to permit axial and rotational motion therebetween. A resilient element, preferably a spring-fluid combination, provides axial shock absorption. A tubular torque-resisting cuff provides rotational resistance, or torsion-resistance. A fluid valve is provided so that the fluid pressure may be varied to adjust the torsion resistance. In another embodiment, a shock module comprises two pylons maintained in a colinear alignment via a guide pin attached to the lower pylon. A resilient element provides shock absorption, and a torque-resisting cuff provides torsion-resistance. In another embodiment, a shock module comprises two pylons telescopingly engaged to permit axial motion therebetween. The pylons also have a polygonal interface to prevent relative rotation therebetween.
