a compensated elevator link is described. in at least one aspect, the compensated elevator link comprises a plurality of cylinder housings and a rod having a plurality of ends, each end comprising a piston head adapted to be slidable received within one of the cylinder housings to define the first and the second hydraulic cylinders. each hydraulic cylinder has at least one annular space for receiving a non-compressible fluid. the stem comprises a passage for receiving a compressible fluid, with each piston head comprising at least one passage to allow selective displacement of the non-compressible fluid between the annular space of the cylinder housing and the passage within the stem during the selective displacement of the hydraulic cylinders between a contracted condition and an extended condition for compression or expansion of the compressible fluid by the non-compressible fluid.
