ABSTRACT:
A suspension component (300) has a pair of elongated slidably coupled in a telescoping arrangement. A pair of attachment plates (305, 306) are fixed to the respective suspension components (311, 314) inside an outer tube of one of the suspension components (314). An elastomeric section (303) is bonded to attachment plates (305, 306), so that collapsing the suspension components (311, 314) results in an extension of the elastomeric section (303). An adjustment mechanism is provided in the form of a rotatable threaded boss (316) mounted on one of the suspension components (314) and rotatably journaled to one of the attachment plates (306). Rotation of the suspension components causes attachment plate (306) to move axially along the length of the suspension component (314).
