Heavy off-road large vehicle suspension strut

Abstract From the Canadian patent

A shock absorber strut that includes an inner and an outer tube which slide one over the other. The combination of a keeper ring and a series of key stops secures the tubes while allowing independent motion therebetween. An elastomeric material contained within the tubes functions as the shock obsorber material and bearing surfaces allow for easy movement between the tubes. A method is also provided for replacement of one of the bearing surfaces without removal of the entire strut from the vehicle even though the elastomeric material is under preload.
