G11 RA Extension Kit is used to allow a Meridian Flip Through. This is done by adding an 1.5" to the RA body and also raising the Saddle Plate by 0.6" . With this kit the motors will not interfere when doing a Meridian Flip Through. An added feature with this kit is the ability to easily remove the DEC axis. This is useful when transporting the G11 to break down the G11 into lighter more manageable pieces.
