I use them and Daystar. I belive they are the same as the look, feel, and part numbers seem to be the same.
As a side note, I find poly bushings work best in the springs (main eye and shackles), transmission mounts, and sway bar mounts. I still use rubber for the engine and body mounts. Better feel and less vibrations.
