a housing defining a main compartment extending along a center axis between a first end and a second end; and
a hydraulic rebound stop (HRS) assembly disposed within the housing adjacent to the first end and including an HRS sleeve having a tubular portion and a flange portion extending radially outwardly from the tubular portion at a first axial end thereof and configured to engage a corresponding ledge for locating the HRS assembly in the main compartment and preventing the HRS assembly from moving toward the second end, the tubular portion defining a plurality of recesses each extending axially from a second axial end of the tubular portion opposite the first axial end and having a depth that gradually decreases along a length of the tubular portion toward the flange portion, wherein the flange portion of the HRS sleeve further extends radially inwardly from the tubular portion.
