Two coaxially disposed rigid tubes are interconnected by a radially secured elastomeric spring member with a fluid chamber formed in the inner tube as well as in the outer tube. The elastomeric member is effective upon relative axial movement between the two tubes to change the volumetric relationship between the two chambers by causing fluid to flow through differently sized orifices within the inner tube. An elastomeric compression bumper is disposed axially between the tubes and upon movement between the tubes of a certain magnitude, the bumper progressively covers some or all of the orifices. The elastomeric spring member provides one or more dissimilar spring rates. Additional load carrying capacity is provided by a gas pressure chamber within the inner tube.
