A hydraulic cylinder assembly having a first portion connected to a first bar. A rod is constrained within a cylindrical recess by a first end and a second end of housing. A maximum travel of a first end of the rod within the housing defines a stroke of the hydraulic cylinder assembly. At least two structures are coupled with each other along a first edge and a second edge to form a space therewithin. A second surface of the structures having a first profile being at a first predetermined distance, and a second profile being at a second predetermined distance, from an axis of each of the at least two structures. The second predetermined distance is greater than the first predetermined distance. The structures are mounted over rod proximate to second end of rod to form a collar for limiting the stroke of the hydraulic cylinder assembly of a machine.
